Affected by scoped storage

../../app/src/main/AndroidManifest.xml:34: WRITE_EXTERNAL_STORAGE no longer provides write access when targeting Android 11+, even when using requestLegacyExternalStorage

 31         tools:ignore="ProtectedPermissions" />
 32     <uses-permission android:name="android.permission.WRITE_SYNC_SETTINGS" />
 33     <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
 34     <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
                   
 35     <uses-permission
 36         android:name="android.permission.REQUEST_INSTALL_PACKAGES"
 37         tools:ignore="ProtectedPermissions" />

Scoped storage is enforced on Android 10+ (or Android 11+ if using requestLegacyExternalStorage). In particular, WRITE_EXTERNAL_STORAGE will no longer provide write access to all files; it will provide the equivalent of READ_EXTERNAL_STORAGE instead.

The MANAGE_EXTERNAL_STORAGE permission can be used to manage all files, but it is rarely necessary and most apps on Google Play are not allowed to use it. Most apps should instead migrate to use scoped storage. To modify or delete files, apps should request write access from the user as described at https://developer.android.com/reference/android/provider/MediaStore#createWriteRequest.

To suppress this error, use the issue id "ScopedStorage" as explained in the Suppressing Warnings and Errors section.

 643 }

Calling String#toLowerCase() or #toUpperCase() without specifying an explicit locale is a common source of bugs. The reason for that is that those methods will use the current locale on the user's device, and even though the code appears to work correctly when you are developing the app, it will fail in some locales. For example, in the Turkish locale, the uppercase replacement for i is not I.

If you want the methods to just perform ASCII replacement, for example to convert an enum name, call String#toUpperCase(Locale.US) instead. If you really want to use the current locale, call String#toUpperCase(Locale.getDefault()) instead.

To suppress this error, use the issue id "DefaultLocale" as explained in the Suppressing Warnings and Errors section.

Using android.media.ExifInterface

../../app/src/main/java/com/w3engineers/unicef/util/helper/ContentUtil.java:11: Avoid using android.media.ExifInterface; use android.support.media.ExifInterface from the support library instead

   8 import android.graphics.Bitmap;
   9 import android.graphics.BitmapFactory;
  10 import android.graphics.Matrix;
  11 import android.media.ExifInterface;                                                                 
  12 import android.media.MediaPlayer;
  13 import android.media.ThumbnailUtils;
  14 import android.net.Uri;

The android.media.ExifInterface implementation has some known security bugs in older versions of Android. There is a new implementation available of this library in the support library, which is preferable.
To suppress this error, use the issue id "ExifInterface" as explained in the Suppressing Warnings and Errors section.

Target SDK attribute is not targeting latest version

../../app/build.gradle:18: Not targeting the latest versions of Android; compatibility modes apply. Consider testing and updating this version. Consult the android.os.Build.VERSION_CODES javadoc for details.

  15     defaultConfig {
  16         applicationId "com.w3engineers.unicef.telemesh"
  17         minSdkVersion 21
  18         targetSdkVersion 30
                                                                        
  19         versionCode 13
  20         versionName "0.1.2-beta"
  21         testInstrumentationRunner 'androidx.test.runner.AndroidJUnitRunner'

When your application runs on a version of Android that is more recent than your targetSdkVersion specifies that it has been tested with, various compatibility modes kick in. This ensures that your application continues to work, but it may look out of place. For example, if the targetSdkVersion is less than 14, your app may get an option button in the UI.

To fix this issue, set the targetSdkVersion to the highest available value. Then test your app to make sure everything works correctly. You may want to consult the compatibility notes to see what changes apply to each version you are adding support for: https://developer.android.com/reference/android/os/Build.VERSION_CODES.html as well as follow this guide:
https://developer.android.com/distribute/best-practices/develop/target-sdk.html

If an application has more than one locale, then all the strings declared in one language should also be translated in all other languages.

If the string should not be translated, you can add the attribute translatable="false" on the <string> element, or you can define all your non-translatable strings in a resource file called donottranslate.xml. Or, you can ignore the issue with a tools:ignore="MissingTranslation" attribute.

You can tell lint (and other tools) which language is the default language in your res/values/ folder by specifying tools:locale="languageCode" for the root <resources> element in your resource file. (The tools prefix refers to the namespace declaration http://schemas.android.com/tools.)
To suppress this error, use the issue id "MissingTranslation" as explained in the Suppressing Warnings and Errors section.

Potential Plurals

../../app/src/main/res/values/strings.xml:211: Formatting %d followed by words ("new"): This should probably be a plural rather than a string

 208     <string name="no_user_available">No User Found Yet</string>
 209     <string name="only_admin_can_change_group_name">Only admin can change group name</string>
 210 
 211     <string name="broadcast_notification">You have %d new broadcast message</string>                
 212     <string name="favourit_button_image">favourit button image</string>
 213     <string name="expanded_image_holder">Expanded image holder</string>
 214     <string name="create_new_wallet">Create New Wallet</string>

This lint check looks for potential errors in internationalization where you have translated a message which involves a quantity and it looks like other parts of the string may need grammatical changes.

For example, rather than something like this:

  <string name="try_again">Try again in %d seconds.</string>

you should be using a plural:

   <plurals name="try_again">
        <item quantity="one">Try again in %d second</item>
        <item quantity="other">Try again in %d seconds</item>
    </plurals>

This will ensure that in other languages the right set of translations are provided for the different quantity classes.

(This check depends on some heuristics, so it may not accurately determine whether a string really should be a quantity. You can use tools:ignore to filter out false positives.

Obsolete SDK_INT Version Check

 32         } else {
 33             free = (statFs.getAvailableBlocks() * statFs.getBlockSize()) / UNIT;

This check flags version checks that are not necessary, because the minSdkVersion (or surrounding known API level) is already at least as high as the version checked for.

Similarly, it also looks for resources in -vNN folders, such as values-v14 where the version qualifier is less than or equal to the minSdkVersion, where the contents should be merged into the best folder.
Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.

Static Field Leaks

../../app/src/main/java/com/w3engineers/unicef/telemesh/data/helper/RmDataHelper.java:85: Do not place Android context classes in static fields (static reference to MeshDataSource which has field context pointing to Context); this is a memory leak

   82 public class RmDataHelper implements BroadcastManager.BroadcastSendCallback {

   84     private static RmDataHelper rmDataHelper = new RmDataHelper();
   85     protected static MeshDataSource rightMeshDataSource;                                            
   86 
   87     protected DataSource dataSource;

A static field will leak contexts.

Non-static inner classes have an implicit reference to their outer class. If that outer class is for example a Fragment or Activity, then this reference means that the long-running handler/loader/task will hold a reference to the activity which prevents it from getting garbage collected.

Similarly, direct field references to activities and fragments from these longer running instances can cause leaks.

ViewModel classes should never point to Views or non-application Contexts.
To suppress this error, use the issue id "StaticFieldLeak" as explained in the Suppressing Warnings and Errors section.

Node can be replaced by a TextView with compound drawables

../../app/src/main/res/layout/item_group_info.xml:6: This tag and its children can be replaced by one <TextView/> and a compound drawable

  8         android:layout_width="match_parent"
  9         android:layout_height="wrap_content"

A LinearLayout which contains an ImageView and a TextView can be more efficiently handled as a compound drawable (a single TextView, using the drawableTop, drawableLeft, drawableRight and/or drawableBottom attributes to draw one or more images adjacent to the text).

If the two widgets are offset from each other with margins, this can be replaced with a drawablePadding attribute.

There's a lint quickfix to perform this conversion in the Eclipse plugin.
To suppress this error, use the issue id "UseCompoundDrawables" as explained in the Suppressing Warnings and Errors section.

Providing an inputType attribute on a text field improves usability because depending on the data to be input, optimized keyboards can be shown to the user (such as just digits and parentheses for a phone number).

The lint detector also looks at the id of the view, and if the id offers a hint of the purpose of the field (for example, the id contains the phrase phone or email), then lint will also ensure that the inputType contains the corresponding type attributes.

If you really want to keep the text field generic, you can suppress this warning by setting inputType="text".

Specify an autofillHints attribute when targeting SDK version 26 or higher or explicitly specify that the view is not important for autofill. Your app can help an autofill service classify the data correctly by providing the meaning of each view that could be autofillable, such as views representing usernames, passwords, credit card fields, email addresses, etc.

The hints can have any value, but it is recommended to use predefined values like 'username' for a username or 'creditCardNumber' for a credit card number. For a list of all predefined autofill hint constants, see the AUTOFILL_HINT_ constants in the View reference at https://developer.android.com/reference/android/view/View.html.

You can mark a view unimportant for autofill by specifying an importantForAutofill attribute on that view or a parent view. See https://developer.android.com/reference/android/view/View.html#setImportantForAutofill(int).

Non-textual widgets like ImageViews and ImageButtons should use the contentDescription attribute to specify a textual description of the widget such that screen readers and other accessibility tools can adequately describe the user interface.

Note that elements in application screens that are purely decorative and do not provide any content or enable a user action should not have accessibility content descriptions. In this case, just suppress the lint warning with a tools:ignore="ContentDescription" attribute.

Note that for text fields, you should not set both the hint and the contentDescription attributes since the hint will never be shown. Just set the hint.

Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.
To suppress this error, use the issue id "ContentDescription" as explained in the Suppressing Warnings and Errors section.

When calling TextView#setText
* Never call Number#toString() to format numbers; it will not handle fraction separators and locale-specific digits properly. Consider using String#format with proper format specifications (%d or %f) instead.
* Do not pass a string literal (e.g. "Hello") to display text. Hardcoded text can not be properly translated to other languages. Consider using Android resource strings instead.
* Do not build messages by concatenating text chunks. Such messages can not be properly translated.

 36                 app:layout_constraintTop_toTopOf="parent"

Using Gravity#LEFT and Gravity#RIGHT can lead to problems when a layout is rendered in locales where text flows from right to left. Use Gravity#START and Gravity#END instead. Similarly, in XML gravity and layout_gravity attributes, use start rather than left.

For XML attributes such as paddingLeft and layout_marginLeft, use paddingStart and layout_marginStart. NOTE: If your minSdkVersion is less than 17, you should add both the older left/right attributes as well as the new start/end attributes. On older platforms, where RTL is not supported and the start/end attributes are unknown and therefore ignored, you need the older left/right attributes. There is a separate lint check which catches that type of error.

(Note: For Gravity#LEFT and Gravity#START, you can use these constants even when targeting older platforms, because the start bitmask is a superset of the left bitmask. Therefore, you can use gravity="start" rather than gravity="left|start".)
Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.
To suppress this error, use the issue id "RtlHardcoded" as explained in the Suppressing Warnings and Errors section.

RtlHardcoded Bidirectional Text Internationalization Warning Priority 5/10

Disabled Checks

One or more issues were not run by lint, either because the check is not enabled by default, or because it was disabled with a command line flag or via one or more lint.xml configuration files in the project directories.

AppLinksAutoVerifyError

Disabled By: Default

Ensures that app links are correctly set and associated with website.

More info: https://g.co/appindexing/applinks

To suppress this error, use the issue id "AppLinksAutoVerifyError" as explained in the Suppressing Warnings and Errors section.

AppLinksAutoVerifyWarning

Disabled By: Default

Ensures that app links are correctly set and associated with website.

More info: https://g.co/appindexing/applinks

To suppress this error, use the issue id "AppLinksAutoVerifyWarning" as explained in the Suppressing Warnings and Errors section.

Assert

Disabled By: Default

Assertions will never be turned on in Android. (It was possible to enable it in Dalvik with adb shell setprop debug.assert 1, but it is not implemented in ART, the runtime for Android 5.0 and later.)

This means that the assertion will never catch mistakes, and you should not use assertions from Java or Kotlin for debug build checking.

Instead, perform conditional checking inside if (BuildConfig.DEBUG) { } blocks. That constant is a static final boolean which will be true only in debug builds, and false in release builds, and the compiler will completely remove all code inside the if-body from the app.

For example, you can replace

    assert(speed > 0, { "Message" })    // Kotlin
    assert speed > 0 : "Message"        // Java

with

    if (BuildConfig.DEBUG && !(speed > 0)) {
        throw new AssertionError("Message")
    }

(Note: This lint check does not flag assertions purely asserting nullness or non-nullness in Java code; these are typically more intended for tools usage than runtime checks.)
To suppress this error, use the issue id "Assert" as explained in the Suppressing Warnings and Errors section.

BackButton

Disabled By: Default

According to the Android Design Guide,

"Other platforms use an explicit back button with label to allow the user to navigate up the application's hierarchy. Instead, Android uses the main action bar's app icon for hierarchical navigation and the navigation bar's back button for temporal navigation."
This check is not very sophisticated (it just looks for buttons with the label "Back"), so it is disabled by default to not trigger on common scenarios like pairs of Back/Next buttons to paginate through screens.

More info: https://material.io/design/

To suppress this error, use the issue id "BackButton" as explained in the Suppressing Warnings and Errors section.

ConvertToWebp

Disabled By: Default

The WebP format is typically more compact than PNG and JPEG. As of Android 4.2.1 it supports transparency and lossless conversion as well. Note that there is a quickfix in the IDE which lets you perform conversion.

Launcher icons must be in the PNG format.
Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.
To suppress this error, use the issue id "ConvertToWebp" as explained in the Suppressing Warnings and Errors section.

DalvikOverride

Disabled By: Default

The Dalvik virtual machine will treat a package private method in one class as overriding a package private method in its super class, even if they are in separate packages.

If you really did intend for this method to override the other, make the method protected instead.

If you did not intend the override, consider making the method private, or changing its name or signature.

Note that this check is disabled be default, because ART (the successor to Dalvik) no longer has this behavior.
To suppress this error, use the issue id "DalvikOverride" as explained in the Suppressing Warnings and Errors section.

DuplicateStrings

Disabled By: Default

Duplicate strings can make applications larger unnecessarily.

This lint check looks for duplicate strings, including differences for strings where the only difference is in capitalization. Title casing and all uppercase can all be adjusted in the layout or in code.

More info: https://developer.android.com/reference/android/widget/TextView.html#attr_android:inputType

To suppress this error, use the issue id "DuplicateStrings" as explained in the Suppressing Warnings and Errors section.

EasterEgg

Disabled By: Default

An "easter egg" is code deliberately hidden in the code, both from potential users and even from other developers. This lint check looks for code which looks like it may be hidden from sight.
To suppress this error, use the issue id "EasterEgg" as explained in the Suppressing Warnings and Errors section.

ExpensiveAssertion

Disabled By: Default

In Kotlin, assertions are not handled the same way as from the Java programming language. In particular, they're just implemented as a library call, and inside the library call the error is only thrown if assertions are enabled.

This means that the arguments to the assert call will always be evaluated. If you're doing any computation in the expression being asserted, that computation will unconditionally be performed whether or not assertions are turned on. This typically turns into wasted work in release builds.

This check looks for cases where the assertion condition is nontrivial, e.g. it is performing method calls or doing more work than simple comparisons on local variables or fields.

You can work around this by writing your own inline assert method instead:

@Suppress("INVISIBLE_REFERENCE", "INVISIBLE_MEMBER")
inline fun assert(condition: () -> Boolean) {
    if (_Assertions.ENABLED && !condition()) {
        throw AssertionError()
    }
}

In Android, because assertions are not enforced at runtime, instead use this:

inline fun assert(condition: () -> Boolean) {
    if (BuildConfig.DEBUG && !condition()) {
        throw AssertionError()
    }
}

To suppress this error, use the issue id "ExpensiveAssertion" as explained in the Suppressing Warnings and Errors section.

FieldGetter

Disabled By: Default

Accessing a field within the class that defines a getter for that field is at least 3 times faster than calling the getter. For simple getters that do nothing other than return the field, you might want to just reference the local field directly instead.

NOTE: As of Android 2.3 (Gingerbread), this optimization is performed automatically by Dalvik, so there is no need to change your code; this is only relevant if you are targeting older versions of Android.

More info: https://developer.android.com/training/articles/perf-tips#internal_get_set

To suppress this error, use the issue id "FieldGetter" as explained in the Suppressing Warnings and Errors section.

GoogleAppIndexingApiWarning

Disabled By: Default

Adds URLs to get your app into the Google index, to get installs and traffic to your app from Google Search.

More info: https://g.co/AppIndexing/AndroidStudio

Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.
To suppress this error, use the issue id "GoogleAppIndexingApiWarning" as explained in the Suppressing Warnings and Errors section.

GoogleAppIndexingWarning

Disabled By: Default

Adds URLs to get your app into the Google index, to get installs and traffic to your app from Google Search.

More info: https://g.co/AppIndexing/AndroidStudio

Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.
To suppress this error, use the issue id "GoogleAppIndexingWarning" as explained in the Suppressing Warnings and Errors section.

IconExpectedSize

Disabled By: Default

There are predefined sizes (for each density) for launcher icons. You should follow these conventions to make sure your icons fit in with the overall look of the platform.

More info: https://material.io/design/iconography/

To suppress this error, use the issue id "IconExpectedSize" as explained in the Suppressing Warnings and Errors section.

ImplicitSamInstance

Disabled By: Default

Kotlin's support for SAM (single accessor method) interfaces lets you pass a lambda to the interface. This will create a new instance on the fly even though there is no explicit constructor call. If you pass one of these lambdas or method references into a method which (for example) stores or compares the object identity, unexpected results may happen.
To suppress this error, use the issue id "ImplicitSamInstance" as explained in the Suppressing Warnings and Errors section.

InvalidPackage

Disabled By: Command line flag

This check scans through libraries looking for calls to APIs that are not included in Android.

When you create Android projects, the classpath is set up such that you can only access classes in the API packages that are included in Android. However, if you add other projects to your libs/ folder, there is no guarantee that those .jar files were built with an Android specific classpath, and in particular, they could be accessing unsupported APIs such as java.applet.

This check scans through library jars and looks for references to API packages that are not included in Android and flags these. This is only an error if your code calls one of the library classes which wind up referencing the unsupported package.
To suppress this error, use the issue id "InvalidPackage" as explained in the Suppressing Warnings and Errors section.

KotlinPropertyAccess

Disabled By: Default

For a method to be represented as a property in Kotlin, strict “bean”-style prefixing must be used.

Accessor methods require a ‘get’ prefix or for boolean-returning methods an ‘is’ prefix can be used.

More info: https://android.github.io/kotlin-guides/interop.html#property-prefixes

To suppress this error, use the issue id "KotlinPropertyAccess" as explained in the Suppressing Warnings and Errors section.

LambdaLast

Disabled By: Default

To improve calling this code from Kotlin,
parameter types eligible for SAM conversion should be last.

More info: https://android.github.io/kotlin-guides/interop.html#lambda-parameters-last

To suppress this error, use the issue id "LambdaLast" as explained in the Suppressing Warnings and Errors section.

LintImplPsiEquals

Disabled By: Default

You should never compare two PSI elements for equality with equals;
use isEquivalentTo(PsiElement) instead.
To suppress this error, use the issue id "LintImplPsiEquals" as explained in the Suppressing Warnings and Errors section.

LintImplUnexpectedDomain

Disabled By: Default

This checks flags URLs to domains that have not been explicitly allowed for use as a documentation source.
To suppress this error, use the issue id "LintImplUnexpectedDomain" as explained in the Suppressing Warnings and Errors section.

LogConditional

Disabled By: Default

The BuildConfig class provides a constant, DEBUG, which indicates whether the code is being built in release mode or in debug mode. In release mode, you typically want to strip out all the logging calls. Since the compiler will automatically remove all code which is inside a if (false) check, surrounding your logging calls with a check for BuildConfig.DEBUG is a good idea.

If you really intend for the logging to be present in release mode, you can suppress this warning with a @SuppressLint annotation for the intentional logging calls.
To suppress this error, use the issue id "LogConditional" as explained in the Suppressing Warnings and Errors section.

MangledCRLF

Disabled By: Default

On Windows, line endings are typically recorded as carriage return plus newline: \r\n.

This detector looks for invalid line endings with repeated carriage return characters (without newlines). Previous versions of the ADT plugin could accidentally introduce these into the file, and when editing the file, the editor could produce confusing visual artifacts.

More info: https://bugs.eclipse.org/bugs/show_bug.cgi?id=375421

To suppress this error, use the issue id "MangledCRLF" as explained in the Suppressing Warnings and Errors section.

MinSdkTooLow

Disabled By: Default

The value of the minSdkVersion property is too low and can be incremented without noticeably reducing the number of supported devices.
Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.
To suppress this error, use the issue id "MinSdkTooLow" as explained in the Suppressing Warnings and Errors section.

NegativeMargin

Disabled By: Default

Margin values should be positive. Negative values are generally a sign that you are making assumptions about views surrounding the current one, or may be tempted to turn off child clipping to allow a view to escape its parent. Turning off child clipping to do this not only leads to poor graphical performance, it also results in wrong touch event handling since touch events are based strictly on a chain of parent-rect hit tests. Finally, making assumptions about the size of strings can lead to localization problems.
To suppress this error, use the issue id "NegativeMargin" as explained in the Suppressing Warnings and Errors section.

NewerVersionAvailable

Disabled By: Default

This detector checks with a central repository to see if there are newer versions available for the dependencies used by this project. This is similar to the GradleDependency check, which checks for newer versions available in the Android SDK tools and libraries, but this works with any MavenCentral dependency, and connects to the library every time, which makes it more flexible but also much slower.
Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.
To suppress this error, use the issue id "NewerVersionAvailable" as explained in the Suppressing Warnings and Errors section.

NoHardKeywords

Disabled By: Default

Do not use Kotlin’s hard keywords as the name of methods or fields.
These require the use of backticks to escape when calling from Kotlin.
Soft keywords, modifier keywords, and special identifiers are allowed.

For example, Mockito’s when function requires backticks when used from Kotlin:

val callable = Mockito.mock(Callable::class.java)
Mockito.`when`(callable.call()).thenReturn(/* … */)

More info: https://android.github.io/kotlin-guides/interop.html#no-hard-keywords

To suppress this error, use the issue id "NoHardKeywords" as explained in the Suppressing Warnings and Errors section.

PermissionImpliesUnsupportedChromeOsHardware

Disabled By: Default

The <uses-permission> element should not require a permission that implies an unsupported Chrome OS hardware feature. Google Play assumes that certain hardware related permissions indicate that the underlying hardware features are required by default. To fix the issue, consider declaring the corresponding uses-feature element with required="false" attribute.

More info: https://developer.android.com/topic/arc/manifest.html#implied-features

Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.
To suppress this error, use the issue id "PermissionImpliesUnsupportedChromeOsHardware" as explained in the Suppressing Warnings and Errors section.

Registered

Disabled By: Default

Activities, services and content providers should be registered in the AndroidManifest.xml file using <activity>, <service> and <provider> tags.

If your activity is simply a parent class intended to be subclassed by other "real" activities, make it an abstract class.

More info: https://developer.android.com/guide/topics/manifest/manifest-intro.html

To suppress this error, use the issue id "Registered" as explained in the Suppressing Warnings and Errors section.

RequiredSize

Disabled By: Default

All views must specify an explicit layout_width and layout_height attribute. There is a runtime check for this, so if you fail to specify a size, an exception is thrown at runtime.

It's possible to specify these widths via styles as well. GridLayout, as a special case, does not require you to specify a size.
To suppress this error, use the issue id "RequiredSize" as explained in the Suppressing Warnings and Errors section.

SelectableText

Disabled By: Default

If a <TextView> is used to display data, the user might want to copy that data and paste it elsewhere. To allow this, the <TextView> should specify android:textIsSelectable="true".

This lint check looks for TextViews which are likely to be displaying data: views whose text is set dynamically. This value will be ignored on platforms older than API 11, so it is okay to set it regardless of your minSdkVersion.
Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.
To suppress this error, use the issue id "SelectableText" as explained in the Suppressing Warnings and Errors section.

StopShip

Disabled By: Default

Using the comment // STOPSHIP can be used to flag code that is incomplete but checked in. This comment marker can be used to indicate that the code should not be shipped until the issue is addressed, and lint will look for these. In Gradle projects, this is only checked for non-debug (release) builds.

In Kotlin, the TODO() method is also treated as a stop ship marker; you can use it to make incomplete code compile, but it will throw an exception at runtime and therefore should be fixed before shipping releases.
Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.
To suppress this error, use the issue id "StopShip" as explained in the Suppressing Warnings and Errors section.

SyntheticAccessor

Disabled By: Default

A private inner class which is accessed from the outer class will force the compiler to insert a synthetic accessor; this means that you are causing extra overhead. This is not important in small projects, but is important for large apps running up against the 64K method handle limit, and especially for libraries where you want to make sure your library is as small as possible for the cases where your library is used in an app running up against the 64K limit.
To suppress this error, use the issue id "SyntheticAccessor" as explained in the Suppressing Warnings and Errors section.

TypographyQuotes

Disabled By: Default

Straight single quotes and double quotes, when used as a pair, can be replaced by "curvy quotes" (or directional quotes). This can make the text more readable.

Note that you should never use grave accents and apostrophes to quote, `like this'.

(Also note that you should not use curvy quotes for code fragments.)

More info: https://en.wikipedia.org/wiki/Quotation_mark

Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.
To suppress this error, use the issue id "TypographyQuotes" as explained in the Suppressing Warnings and Errors section.

UnknownNullness

Disabled By: Default

To improve referencing this code from Kotlin, consider adding
explicit nullness information here with either @NonNull or @Nullable.

You can set the environment variable
ANDROID_LINT_NULLNESS_IGNORE_DEPRECATED=true
if you want lint to ignore classes and members that have been annotated with
@Deprecated.

More info: https://android.github.io/kotlin-guides/interop.html#nullability-annotations

To suppress this error, use the issue id "UnknownNullness" as explained in the Suppressing Warnings and Errors section.

UnpackedNativeCode

Disabled By: Default

This app loads native libraries using System.loadLibrary().

Consider adding android:extractNativeLibs="false" to the <application> tag in AndroidManifest.xml. Starting with Android 6.0, this will make installation faster, the app will take up less space on the device and updates will have smaller download sizes.
Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.
To suppress this error, use the issue id "UnpackedNativeCode" as explained in the Suppressing Warnings and Errors section.

UnsupportedChromeOsHardware

Disabled By: Default

The <uses-feature> element should not require this unsupported Chrome OS hardware feature. Any uses-feature not explicitly marked with required="false" is necessary on the device to be installed on. Ensure that any features that might prevent it from being installed on a Chrome OS device are reviewed and marked as not required in the manifest.

More info: https://developer.android.com/topic/arc/manifest.html#incompat-entries

Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.
To suppress this error, use the issue id "UnsupportedChromeOsHardware" as explained in the Suppressing Warnings and Errors section.

UnusedIds

Disabled By: Default

This resource id definition appears not to be needed since it is not referenced from anywhere. Having id definitions, even if unused, is not necessarily a bad idea since they make working on layouts and menus easier, so there is not a strong reason to delete these.

The unused resource check can ignore tests. If you want to include resources that are only referenced from tests, consider packaging them in a test source set instead.

You can include test sources in the unused resource check by setting the system property lint.unused-resources.include-tests=true, and to exclude them (usually for performance reasons), use lint.unused-resources.exclude-tests=true.
Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.
To suppress this error, use the issue id "UnusedIds" as explained in the Suppressing Warnings and Errors section.

ValidActionsXml

Disabled By: Default

Ensures that an actions XML file is properly formed
To suppress this error, use the issue id "ValidActionsXml" as explained in the Suppressing Warnings and Errors section.

WrongThreadInterprocedural

Disabled By: Default

Searches for interprocedural call paths that violate thread annotations in the program. Tracks the flow of instantiated types and lambda expressions to increase accuracy across method boundaries.

More info: https://developer.android.com/guide/components/processes-and-threads.html#Threads

To suppress this error, use the issue id "WrongThreadInterprocedural" as explained in the Suppressing Warnings and Errors section.

Suppressing Warnings and Errors

Lint errors can be suppressed in a variety of ways:

1. With a @SuppressLint annotation in the Java code
2. With a tools:ignore attribute in the XML file
3. With a //noinspection comment in the source code
4. With ignore flags specified in the build.gradle file, as explained below
5. With a lint.xml configuration file in the project
6. With a lint.xml configuration file passed to lint via the --config flag
7. With the --ignore flag passed to lint.

To suppress a lint warning with an annotation, add a @SuppressLint("id") annotation on the class, method or variable declaration closest to the warning instance you want to disable. The id can be one or more issue id's, such as "UnusedResources" or {"UnusedResources","UnusedIds"}, or it can be "all" to suppress all lint warnings in the given scope.

To suppress a lint warning with a comment, add a //noinspection id comment on the line before the statement with the error.

To suppress a lint warning in an XML file, add a tools:ignore="id" attribute on the element containing the error, or one of its surrounding elements. You also need to define the namespace for the tools prefix on the root element in your document, next to the xmlns:android declaration:
xmlns:tools="http://schemas.android.com/tools"

To suppress a lint warning in a build.gradle file, add a section like this:

android {
    lintOptions {
        disable 'TypographyFractions','TypographyQuotes'
    }
}

Here we specify a comma separated list of issue id's after the disable command. You can also use warning or error instead of disable to change the severity of issues.

To suppress lint warnings with a configuration XML file, create a file named lint.xml and place it at the root directory of the module in which it applies.

The format of the lint.xml file is something like the following:

<?xml version="1.0" encoding="UTF-8"?>
<lint>
    <!-- Ignore everything in the test source set -->
    <issue id="all">
        <ignore path="\*/test/\*" />
    </issue>

    <!-- Disable this given check in this project -->
    <issue id="IconMissingDensityFolder" severity="ignore" />

    <!-- Ignore the ObsoleteLayoutParam issue in the given files -->
    <issue id="ObsoleteLayoutParam">
        <ignore path="res/layout/activation.xml" />
        <ignore path="res/layout-xlarge/activation.xml" />
        <ignore regexp="(foo|bar)\.java" />
    </issue>

    <!-- Ignore the UselessLeaf issue in the given file -->
    <issue id="UselessLeaf">
        <ignore path="res/layout/main.xml" />
    </issue>

    <!-- Change the severity of hardcoded strings to "error" -->
    <issue id="HardcodedText" severity="error" />
</lint>

To suppress lint checks from the command line, pass the --ignore flag with a comma separated list of ids to be suppressed, such as:
$ lint --ignore UnusedResources,UselessLeaf /my/project/path

For more information, see https://developer.android.com/studio/write/lint.html#config
