I can't compile a default new project for Android 2.1 because(?) the JDK used by Android Studio is JDK 1.7 but it should be JDK 1.6. To change it I go to File- Project Structure and try to find the JDK 1.6 location. But when I select its directory and press OK I get the following error: Please choose a valid JDK directory. Xamarin.Android uses the Java Development Kit (JDK) to integrate with the Android SDK for building Android apps and running the Android designer. The latest versions of the Android SDK (API 24 and higher) require JDK 8 (1.8) or the Microsoft Mobile OpenJDK Preview. Because the Android SDK tools available from Google are not yet compatible with.

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.

2. Java SE Development Kit 8u291 Demos and Samples Downloads. Demos and samples of common tasks and new functionality available on JDK 8. JavaFX 8 demos and samples are included in the JDK 8 Demos and Samples packages. The source code provided with demos and samples for the JDK is meant to illustrate the usage of a given feature or technique.
3. Java 8 language feature support (Android Gradle Plugin 3.0.0+) To start using supported Java 8 language features, update the Android plugin to 3.0.0 (or higher). After that, for each module that uses Java 8 language features (either in its source code or through dependencies), update the module's build.gradle file, as shown below: Groovy Kotlin.

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.

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:

Jdk 8 For Android Studio

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:

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+ language features desugaring that is available from Android GradlePlugin 3.0.0 does not make any additional classes and APIs (such asjava.util.stream.*) available for use on older Android releases. Support forpartial Java API desugaring is available from Android Gradle Plugin 4.0.0 orhigher and is described in the following section.

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.

The following set of APIs are supported when building your app using AndroidGradle plugin 4.0.0 or higher:

• Sequential streams (java.util.stream)
• A subset of java.time
• java.util.function
• Recent additions to java.util.{Map,Collection,Comparator}
• Optionals (java.util.Optional, java.util.OptionalInt andjava.util.OptionalDouble) and some other new classes useful with the aboveAPIs
• Some additions to java.util.concurrent.atomic (new methods onAtomicInteger, AtomicLong and AtomicReference)
• ConcurrentHashMap (with bug fixes for Android 5.0)

For a complete list of supported APIs, visitJava 8+ APIs available through desugaring.

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 app module’sbuild.gradle file:

Note that you may also need to include the above code snippet in a librarymodule's build.gradle file if:

• The library module's instrumented tests use these language APIs (eitherdirectly or through the library module or its dependencies). This is so thatthe missing APIs are provided for your instrumented test APK.

• You want to run lint on the library module in isolation. This is to helplint recognize valid usages of the language APIs and avoid reporting falsewarnings.

Also note that API desugaring can be combined with shrinking, but onlywhen using the R8 shrinker.
