There are some combinations of libraries, or tools and libraries, that are incompatible, or can lead to bugs. One such incompatibility is compiling with a version of the Android support libraries that is not the latest version (or in particular, a version lower than your <code>targetSdkVersion</code>).<br/>Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.<br>

Calling <code>String#toLowerCase()</code> or <code>#toUpperCase()</code> <b>without specifying an explicit locale</b> 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 <code>i</code> is <b>not</b> <code>I</code>.<br/>
|
<br/>
|
If you want the methods to just perform ASCII replacement, for example to convert an enum name, call <code>String#toUpperCase(Locale.US)</code> instead. If you really want to use the current locale, call <code>String#toUpperCase(Locale.getDefault())</code> instead.<br/><div class="moreinfo">More info: <a href="http://developer.android.com/reference/java/util/Locale.html#default_locale">http://developer.android.com/reference/java/util/Locale.html#default_locale</a>

This check scans through libraries looking for calls to APIs that are not included in Android.<br/>
|
<br/>
|
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.<br/>
|
<br/>
|
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.<br/>To suppress this error, use the issue id "InvalidPackage" as explained in the <a href="#SuppressInfo">Suppressing Warnings and Errors</a> section.<br/>

When your application runs on a version of Android that is more recent than your <code>targetSdkVersion</code> 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 <code>targetSdkVersion</code> is less than 14, your app may get an option button in the UI.<br/>
|
<br/>
|
To fix this issue, set the <code>targetSdkVersion</code> 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: <a href="http://developer.android.com/reference/android/os/Build.VERSION_CODES.html">http://developer.android.com/reference/android/os/Build.VERSION_CODES.html</a> as well as follow this guide:<br/>

This detector looks for usages of libraries where the version you are using is not the current stable release. Using older versions is fine, and there are cases where you deliberately want to stick with an older version. However, you may simply not be aware that a more recent version is available, and that is what this lint check helps find.<br/>Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.<br>

The given layout_param is not defined for the given layout, meaning it has no effect. This usually happens when you change the parent layout or move view code around without updating the layout params. This will cause useless attribute processing at runtime, and is misleading for others reading the layout so the parameter should be removed.<br/>Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.<br>

A static field will leak contexts.<br/>
|
<br/>
|
Non-static inner classes have an implicit reference to their outer class. If that outer class is for example a <code>Fragment</code> or <code>Activity</code>, 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.<br/>
|
<br/>
|
Similarly, direct field references to activities and fragments from these longer running instances can cause leaks.<br/>
|
<br/>

ViewModel classes should never point to Views or non-application Contexts.<br/>To suppress this error, use the issue id "StaticFieldLeak" as explained in the <a href="#SuppressInfo">Suppressing Warnings and Errors</a> section.<br/>

Since this Handler is declared as an inner class, it may prevent the outer class from being garbage collected. If the Handler is using a Looper or MessageQueue for a thread other than the main thread, then there is no issue. If the Handler is using the Looper or MessageQueue of the main thread, you need to fix your Handler declaration, as follows: Declare the Handler as a static class; In the outer class, instantiate a WeakReference to the outer class and pass this object to your Handler when you instantiate the Handler; Make all references to members of the outer class using the WeakReference object.<br/>To suppress this error, use the issue id "HandlerLeak" as explained in the <a href="#SuppressInfo">Suppressing Warnings and Errors</a> section.<br/>

Icons will look best if a custom version is provided for each of the major screen density classes (low, medium, high, extra high). This lint check identifies icons which do not have complete coverage across the densities.<br/>

Low density is not really used much anymore, so this check ignores the ldpi density. To force lint to include it, set the environment variable <code>ANDROID_LINT_INCLUDE_LDPI=true</code>.

Non-textual widgets like ImageViews and ImageButtons should use the <code>contentDescription</code> attribute to specify a textual description of the widget such that screen readers and other accessibility tools can adequately describe the user interface.<br/>
|
<br/>
|
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.<br/>
|
<br/>
|
Note that for text fields, you should not set both the <code>hint</code> and the <code>contentDescription</code> attributes since the hint will never be shown. Just set the <code>hint</code>. See <a href="http://developer.android.com/guide/topics/ui/accessibility/checklist.html#special-cases">http://developer.android.com/guide/topics/ui/accessibility/checklist.html#special-cases</a>.<br/>Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.<br>

When calling <code>TextView#setText</code><br/>
|
* Never call <code>Number#toString()</code> to format numbers; it will not handle fraction separators and locale-specific digits properly. Consider using <code>String#format</code> with proper format specifications (<code>%d</code> or <code>%f</code>) instead.<br/>
|
* 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.<br/>
|
* Do not build messages by concatenating text chunks. Such messages can not be properly translated.<br/><div class="moreinfo">More info: <a href="http://developer.android.com/guide/topics/resources/localization.html">http://developer.android.com/guide/topics/resources/localization.html</a>

|
Hardcoding text attributes directly in layout files is bad for several reasons:<br/>
|
<br/>
|
* When creating configuration variations (for example for landscape or portrait) you have to repeat the actual text (and keep it up to date when making changes)<br/>
|
<br/>
|
* The application cannot be translated to other languages by just adding new translations for existing string resources.<br/>
|
<br/>
|
There are quickfixes to automatically extract this hardcoded string into a resource lookup.<br/>To suppress this error, use the issue id "HardcodedText" as explained in the <a href="#SuppressInfo">Suppressing Warnings and Errors</a> section.<br/>

|
Using <code>Gravity#LEFT</code> and <code>Gravity#RIGHT</code> can lead to problems when a layout is rendered in locales where text flows from right to left. Use <code>Gravity#START</code> and <code>Gravity#END</code> instead. Similarly, in XML <code>gravity</code> and <code>layout_gravity</code> attributes, use <code>start</code> rather than <code>left</code>.<br/>
|
<br/>
|
For XML attributes such as paddingLeft and <code>layout_marginLeft</code>, use <code>paddingStart</code> and <code>layout_marginStart</code>. <b>NOTE</b>: If your <code>minSdkVersion</code> is less than 17, you should add <b>both</b> the older left/right attributes <b>as well as</b> the new start/right attributes. On older platforms, where RTL is not supported and the start/right 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.<br/>
|
<br/>
|
(Note: For <code>Gravity#LEFT</code> and <code>Gravity#START</code>, you can use these constants even when targeting older platforms, because the <code>start</code> bitmask is a superset of the <code>left</code> bitmask. Therefore, you can use <code>gravity="start"</code> rather than <code>gravity="left|start"</code>.)<br/>Note: This issue has an associated quickfix operation in Android Studio and IntelliJ IDEA.<br>

According to the Android Design Guide,<br/>

"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."<br/>

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.<br/><div class="moreinfo">More info: <a href="http://developer.android.com/design/patterns/pure-android.html">http://developer.android.com/design/patterns/pure-android.html</a>

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.<br/>

If you really did intend for this method to override the other, make the method <code>protected</code> instead.<br/>

If you did <b>not</b> intend the override, consider making the method private, or changing its name or signature.<br/>

The BuildConfig class (available in Tools 17) provides a constant, "DEBUG", which indicates whether the code is being built in release mode or in debug mode.

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.<br/>To suppress this error, use the issue id "NegativeMargin" as explained in the <a href="#SuppressInfo">Suppressing Warnings and Errors</a> section.<br/>

Lint errors can be suppressed in a variety of ways:<br/>
|
<br/>
|
1. With a <code>@SuppressLint</code> annotation in the Java code<br/>
|
2. With a <code>tools:ignore</code> attribute in the XML file<br/>
|
3. With a //noinspection comment in the source code<br/>
|
4. With ignore flags specified in the <code>build.gradle</code> file, as explained below<br/>
|
5. With a <code>lint.xml</code> configuration file in the project<br/>
|
6. With a <code>lint.xml</code> configuration file passed to lint via the --config flag<br/>
|
7. With the --ignore flag passed to lint.<br/>
|
<br/>
|
To suppress a lint warning with an annotation, add a <code>@SuppressLint("id")</code> 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 <code>"UnusedResources"</code> or <code>{"UnusedResources","UnusedIds"}</code>, or it can be <code>"all"</code> to suppress all lint warnings in the given scope.<br/>
|
<br/>
|
To suppress a lint warning with a comment, add a <code>//noinspection id</code> comment on the line before the statement with the error.<br/>
|
<br/>
|
To suppress a lint warning in an XML file, add a <code>tools:ignore="id"</code> 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 <code>xmlns:android</code> declaration:<br/>
|
<code>xmlns:tools="http://schemas.android.com/tools"</code><br/>
|
<br/>
|
To suppress a lint warning in a <code>build.gradle</code> file, add a section like this:<br/>
|
<br/>
|
android {<br/>
|
lintOptions {<br/>
|
disable 'TypographyFractions','TypographyQuotes'<br/>
|
}<br/>
|
}<br/>
|
<br/>
|
Here we specify a comma separated list of issue id's after the disable command. You can also use <code>warning</code> or <code>error</code> instead of <code>disable</code> to change the severity of issues.<br/>
|
<br/>
|
To suppress lint warnings with a configuration XML file, create a file named <code>lint.xml</code> and place it at the root directory of the module in which it applies.<br/>
|
<br/>
|
The format of the <code>lint.xml</code> file is something like the following:<br/>
|
<br/>
|
<?xml version="1.0" encoding="UTF-8"?><br/>
|
<lint><br/>
|
<!-- Ignore everything in the test source set --><br/>
