<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

plugin you are using, check the version declaration in the project-level
<strong>build.gradle</strong> file. </p>

<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:
<pre>
...
     dependencies {
         classpath 'com.android.tools.build:gradle:1.1'
     }
...
</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>
