<p>The Android build system uses the Android Plugin for Gradle to support building Android
applications with the <a href="http://www.gradle.org/">Gradle</a> build toolkit. The plugin runs
independent of Android Studio so the plugin and the Gradle build system can be updated
independently of Android Studio.</p>

<p class="note"><strong>Note:</strong> When you update Android Studio or open a project in a
previous version of Android Studio, Android Studio prompts you to automatically update the plugin
and Gradle to the latest available versions. You can choose to accept these updates based
on your project's build requirements. </p>


<h2 id="revisions">Revisions</h2>

<p>The sections below provide notes about successive releases of
the Android Plugin for Gradle, as denoted by revision number. To determine what revision of the
plugin you are using, check the version declaration in the project-level
<strong>build.gradle</strong> file. </p>

    <dt>General Notes:</dt>
    <dd>
      <ul>
      <li>Enhanced support for running unit tests with Gradle.  </li>
        <ul>
          <li>Added support to include Java-style resources in the classpath when running unit
            tests directly from Gradle.
          </li>
          <li>Added unit test dependency support for Android ARchive (AAR) artifacts.
          </li>
          <li>Added support for the <code>unitTestVariants</code> property so unit test variants
            can be manipulated using the <code>build.gradle</code> file.
          </li>
          <li>Added the <code>unitTest.all</code> code block under <code>testOptions</code> to
            configure customized tasks for unit test. The following sample code shows how to add
            unit test configuration settings using this new option:
<pre>
android {
  testOptions {
    unitTest.all {
      jvmArgs '-XX:MaxPermSize=256m' // Or any other gradle option.
    }
  }
}
</pre>
           </li>
          <li>Fixed the handling of enums and public instance fields in the packaging of the
           <code>mockable-android.jar</code> file.
          </li>
          <li>Fixed library project task dependencies so test classes recompile after changes.
          </li>
          </ul>
        <li>Added the <code>testProguardFile</code> property to apply
          <a href="{@docRoot}tools/help/proguard.html">ProGuard</a> files when minifying a test APK.
        </li>
        <li>Added the <code>timeOut</code> property to the <code>adbOptions</code> code block
          for setting the maximum recording time for
          <a href="{@docRoot}tools/help/adb.html">Android Debug Bridge</a> screen recording.
        </li>
        <li>Added support for 280 dpi resources.
        </li>
        <li>Improved performance during project evaluation.
        </li>

      <ul>
       <li>Enabled
       <a href="{@docRoot}training/activity-testing/activity-unit-testing.html">unit tests</a> to
       run on the local JVM against a special version of the <code>android.jar</code> file that is
       compatible with popular mocking frameworks, for example Mockito. </li>
       <li>Added new test tasks <code>testDebug</code>, <code>testRelease</code>, and
       <code>testMyFlavorDebug</code> when using product flavors. </li>
       <li>Added new source folders recognized as unit tests: <code>src/test/java/</code>,
       <code>src/testDebug/java/</code>, <code>src/testMyFlavor/java/</code>.
       <li>Added new configurations in the <code>build.gradle</code> file for declaring test-only
       dependencies, for example, <code>testCompile 'junit:junit:4.11'</code>,
       <code>testMyFlavorCompile 'some:library:1.0'</code>.
        <p class="note"><strong>Note:</strong> Test-only dependencies are not currently compatible
        with Jack (Java Android Compiler Kit). </p>
       </li>
       <li>Added the <code>android.testOptions.unitTests.returnDefaultValues</code> option to
       control the behaviour of the mockable android.jar. </li>
      </ul>
      <li>Replaced <code>Test</code> in test task names with <code>AndroidTest</code>.
      For example, the <code>assembleDebugTest</code> task is now
      <code>assembleDebugAndroidTest</code> task. Unit test tasks still have <code>UnitTest</code>
      in the task name, for example <code>assembleDebugUnitTest</code>. </li>
      <li>Modified <a href="{@docRoot}tools/help/proguard.html">ProGuard</a> configuration files to
      no longer apply to the test APK. If minification is enabled, ProGuard processes the test APK
      and applies only the mapping file that is generated when minifying the main APK. </li>
      <li>Updated dependency management</li>
       <ul>
       <li>Fixed issues using <code>provided</code> and <code>package</code> scopes.
         <p class="note"><strong>Note:</strong> These scopes are incompatible with AAR
         (Android ARchive) packages and will cause a build with AAR packages to fail.</p>
       </li>
       <li>Modified dependency resolution to compare the dependencies of an app under test and the
       test app. If an artifact with the same version is found for both apps, it's not included with
       the test app and is packaged only with the app under test. If an artifact with a different
       version is found for both apps, the build fails.</li>
       </ul>

      <li>Added support for <code>anyDpi</code>
      <a href="{@docRoot}guide/topics/resources/providing-resources.html"> resource qualifier</a>
      in resource merger. </li>
      <li>Improved evaluation and IDE sync speeds for projects with a large number of

<h2>Updating the Android Plugin for Gradle Version</h2>
<p>The Android Plugin for Gradle version is specified in the
<strong>File &gt; Project Structure</strong> menu or the project-level
<code>build.gradle</code> file. The plugin version applies to all modules built in that
Android Studio project. This example updates the Android Plugin for Gradle to version 1.1.0:
<pre>
...
     dependencies {
         classpath 'com.android.tools.build:gradle:1.1.0'
     }
...
</pre>


<p class="caution"><strong>Caution:</strong> You should not use dynamic dependencies (+) in
version numbers. Using this feature can cause unexpected version updates and difficulty
resolving version differences. </p>

<p>If you're building with Gradle but using not Android Studio, the build process downloads the
latest Android Plugin for Gradle plugin when it runs. </p>



<h2>Updating the Gradle Version </h2>

<p>Android Studio requires Gradle version 2.2.1 or later. To view and
update the Gradle version, edit the Gradle distribution reference in the
<code>gradle/wrapper/gradle-wrapper.properties</code> file. This example shows the
Android Plugin for Gradle version set to 2.2.1.</p>

<pre>
...
distributionUrl=http\://services.gradle.org/distributions/gradle-2.2.1-all.zip
...
</pre>
