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.

This check finds attributes set in XML files that were introduced in a version newer than the oldest version targeted by your application (with the minSdkVersion attribute).

This is not an error; the application will simply ignore the attribute. However, if the attribute is important to the appearance or functionality of your application, you should consider finding an alternative way to achieve the same result with only available attributes, and then you can optionally create a copy of the layout in a layout-vNN folder which will be used on API NN or higher where you can take advantage of the newer attribute.

Note: This check does not only apply to attributes. For example, some tags can be unused too, such as the new <tag> element in layouts introduced in API 21.
Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.
To suppress this error, use the issue id "UnusedAttribute" as explained in the Suppressing Warnings and Errors section.

FragmentContainerView replaces the <fragment> tag as the preferred way of adding fragments via XML. Unlike the <fragment> tag, FragmentContainerView uses a normal FragmentTransaction under the hood to add the initial fragment, allowing further FragmentTransaction operations on the FragmentContainerView and providing a consistent timing for lifecycle events.

The <activity> element should not be locked to any orientation so that users can take advantage of the multi-window environments and larger screens available on Android. To fix the issue, consider declaring the corresponding activity element with `screenOrientation="unspecified"or "fullSensor"` attribute.

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.

Android defines a number of different quantity strings, such as zero, one, few and many. However, many languages do not distinguish grammatically between all these different quantities.

This lint check looks at the quantity strings defined for each translation and flags any quantity strings that are unused (because the language does not make that quantity distinction, and Android will therefore not look it up).

For example, in Chinese, only the other quantity is used, so even if you provide translations for zero and one, these strings will not be returned when getQuantityString() is called, even with 0 or 1.

  83             android:launchMode="singleInstance"
  84             android:noHistory="true"

Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined. Otherwise, installation will fail. Set it to true to make this activity accessible to other apps, and false to limit it to be used only by this app or the OS. For launch activities, this should be set to true; otherwise, the app will fail to launch.

Previously, android:exported for components without any intent filters present used to default to false, and when intent filters were present, the default was true. Defaults which change value based on other values are confusing and lead to apps accidentally exporting components as a side-effect of adding intent filters. This is a security risk, and we have made this change to avoid introducing accidental vulnerabilities.

While the default without intent filters remains unchanged, it is now required to explicitly specify a value when intent filters are present. Any app failing to meet this requirement will fail to install on any Android version after Android 11.

We recommend setting android:exported to false (even on previous versions of Android prior to this requirement) unless you have a good reason to export a particular component.

When a LinearLayout is used to distribute the space proportionally between nested layouts, the baseline alignment property should be turned off to make the layout computation faster.

Inefficient layout weight

 19             android:gravity="center"

When only a single widget in a LinearLayout defines a weight, it is more efficient to assign a width/height of 0dp to it since it will absorb all the remaining space anyway. With a declared width/height of 0dp it does not have to measure its own size first.
Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.

Notification Launches Services or BroadcastReceivers

../../src/main/java/com/beemdevelopment/aegis/services/NotificationService.java:36: Notifications should only launch a BroadcastReceiver from notification actions (addAction)

 33              .setContentText(getString(R.string.vault_unlocked_state))
 34              .setPriority(NotificationCompat.PRIORITY_DEFAULT)

 37 
 38      NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
 39      notificationManager.notify(VAULT_UNLOCKED_ID, builder.build());

../../src/main/java/com/beemdevelopment/aegis/services/NotificationService.java:29

This BroadcastReceiver intent is launched from a notification; this is discouraged except as notification actions

 26 
 27   public void serviceMethod() {
 28       Intent intentAction = new Intent(CODE_LOCK_VAULT_ACTION);
 29       PendingIntent lockDatabaseIntent = PendingIntent.getBroadcast(this, 1, intentAction, 0);    
 30       NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CODE_LOCK_STATUS_ID)

 32               .setContentTitle(getString(R.string.app_name_full))

Notifications should only launch activities -- that's what users expect (and has been the guidance in both the Android SDK and Material Design documentation for a while).

A Service or a BroadcastReceiver should not be used as an intermediate, because this can lead to significant performance problems, and as a result, this will not be allowed in Android 12.

If a drawable resource appears as an .xml file in the drawable/ folder, it's usually not intentional for it to also appear as a bitmap using the same name; generally you expect the drawable XML file to define states and each state has a corresponding drawable bitmap.
To suppress this error, use the issue id "IconXmlAndPng" as explained in the Suppressing Warnings and Errors section.

Image defined in density-independent drawable folder

Found bitmap drawable res/drawable/app_icon.png in densityless folder
../../src/main/res/drawable/ic_aegis_iconx.png:

Found bitmap drawable res/drawable/ic_aegis_iconx.png in densityless folder

The res/drawable folder is intended for density-independent graphics such as shapes defined in XML. For bitmaps, move it to drawable-mdpi and consider providing higher and lower resolution versions in drawable-ldpi, drawable-hdpi and drawable-xhdpi. If the icon really is density independent (for example a solid color) you can place it in drawable-nodpi.

 10         android:checkable="true"

Using showAsAction="always" in menu XML, or MenuItem.SHOW_AS_ACTION_ALWAYS in Java code is usually a deviation from the user interface style guide.Use ifRoom or the corresponding MenuItem.SHOW_AS_ACTION_IF_ROOM instead.

If always is used sparingly there are usually no problems and behavior is roughly equivalent to ifRoom but with preference over other ifRoom items. Using it more than twice in the same menu is a bad idea.

This check looks for menu XML files that contain more than two always actions, or some always actions and no ifRoom actions. In Java code, it looks for projects that contain references to MenuItem.SHOW_AS_ACTION_ALWAYS and no references to MenuItem.SHOW_AS_ACTION_IF_ROOM.
Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.

Accessibility in Custom Views

../../src/main/java/com/beemdevelopment/aegis/ui/views/EntryAdapter.java:426: onTouch should call View#performClick when a click is detected

 423         });
 424         holder.itemView.setOnTouchListener(new View.OnTouchListener() {
 425             @Override
 426             public boolean onTouch(View v, MotionEvent event) {                                     
 427                 // Start drag if this is the only item selected
 428                 if (event.getActionMasked() == MotionEvent.ACTION_MOVE
 429                         && _selectedEntries.size() == 1

If a View that overrides onTouchEvent or uses an OnTouchListener does not also implement performClick and call it when clicks are detected, the View may not handle accessibility actions properly. Logic handling the click actions should ideally be placed in View#performClick as some accessibility services invoke performClick when a click action should occur.
To suppress this error, use the issue id "ClickableViewAccessibility" as explained in the Suppressing Warnings and Errors section.

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.

RtlSymmetry Bidirectional Text Internationalization Warning Priority 6/10

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.

AppLinksAutoVerify

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 "AppLinksAutoVerify" 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.

Previously, launcher icons were required to be in the PNG format but that restriction is no longer there, so lint now flags these.
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()
    }
}

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

InvalidPackage

Disabled By: Default

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.

LintDocExample

Disabled By: Default

Lint's tool for generating documentation for each issue has special support for including a code example which shows how to trigger the report. It will pick the first unit test it can find and pick out the source file referenced from the error message, but you can instead designate a unit test to be the documentation example, and in that case, all the files are included.

To designate a unit test as the documentation example for an issue, name the test testDocumentationExample, or if your detector reports multiple issues, testDocumentationExample<Id>, such as
testDocumentationExampleMyId.
To suppress this error, use the issue id "LintDocExample" 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.

MediaCapabilities

Disabled By: Default

In Android 12 and higher, an app that opens media files should explicitly specify media formats that it doesn't support, so the OS can provide a transcoded file instead.
To suppress this error, use the issue id "MediaCapabilities" 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.

MissingTranslation

Disabled By: Command line flag

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.)
Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.
To suppress this error, use the issue id "MissingTranslation" 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.

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.
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.
Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.
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.)

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

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

VectorDrawableCompat

Disabled By: Default

To use VectorDrawableCompat, you need to make two modifications to your project. First, set android.defaultConfig.vectorDrawables.useSupportLibrary = true in your build.gradle file, and second, use app:srcCompat instead of android:src to refer to vector drawables.

More info:

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

VulnerableCordovaVersion

Disabled By: Default

The version of Cordova used in the app is vulnerable to security issues. Please update to the latest Apache Cordova version.

More info: https://cordova.apache.org/announcements/2015/11/20/security.html

To suppress this error, use the issue id "VulnerableCordovaVersion" 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
