Android Gradle plugin 3.0.0 and later support all Java 7 language features anda subset of Java 8 language features that vary by platform version. Whenbuilding your app using Android Gradle plugin 4.0.0 and higher, you can use anumber of Java 8 language APIs without requiring a minimum API level for yourapp.
This page describes the Java 8 language features you can use, how to properlyconfigure your project to use them, and any known issues you may encounter.Also see the following video for an overview.
Note: When developing apps for Android, using Java 8language features is optional. You can keep your project's source and targetcompatibility values set to Java 7, but you still need to compile using JDK 8.
The Android Gradle plugin provides built-in support for using certain Java 8language features and third-party libraries that use them. As shown in figure 1,the default toolchain implements the new language features by performingbytecode transformations, called desugar, as part of the D8/R8 compilationof class files into dex code.

Java 8 language feature support (Android Gradle Plugin 3.0.0+)
To start using supported Java 8 language features,update the Android pluginto 3.0.0 (or higher). After that, for each module that uses Java 8language features (either in its source code or through dependencies),update the module's build.gradle file, as shown below:
When building your app using Android Gradle plugin 3.0.0 and higher, the plugindoes not support all Java 8 language features. The following language featuresare now available on any API level:

| Java 8 language feature | Notes |
|---|---|
| Lambda expressions | Note that Android does not support the serialization of lambda expressions. |
| Method references | |
| Type annotations | Type annotation information is only available at compile time, and not at runtime. Also, the platform supports TYPE in API level 24 and below, but not ElementType.TYPE_USE or ElementType.TYPE_PARAMETER. |
| Default and static interface methods | |
| Repeating annotations |
In addition to the Java 8 language features above, plugin versions 3.0.0and later extend support fortry-with-resources to all Android API levels.
Desugar currently doesn't supportMethodHandle.invoke orMethodHandle.invokeExact.If your source code or one of your module dependencies use one of these methodsyou need to specify minSdkVersion 26 or higher. Otherwise, you get thefollowing error:
In some cases, your module may not be using the invoke or invokeExactmethods even when they're included in a library dependency. So, to keep usingthat library with minSdkVersion 25 or lower,enable code shrinking to removeunused methods. If that doesn't work, consider using an alternative library thatdoesn't use the unsupported methods.

Java 8+ API desugaring support (Android Gradle Plugin 4.0.0+)
If you're building your app using Android Gradle plugin 4.0.0 or higher, theplugin extends support for using a number of Java 8 language APIs withoutrequiring a minimum API level for your app.
This additional support for older platform versions is possible because plugin4.0.0 and higher extend the desugaring engine to also desugar Java language APIs.So, you can include standard language APIs that were available only inrecent Android releases (such as java.util.streams) in apps that support olderversions of Android.

To support these language APIs, the plugin compiles a separate DEX filethat contains an implementation of the missing APIs and includes it in your app.The desugaring process rewrites your app’s code to instead use this library atruntime.

To enable support for these language APIs on any version of the Android platform,update the Android pluginto 4.0.0 (or higher) and include the following in your module’s build.gradlefile:
