Merge "docs: Updated documentaion for data binding set up with new 1.5.0...

— it's a support library, so you can use it with all Android platform

versions back to <strong>Android 2.1</strong> (API level 7+).</p>

<p>To use data binding, Android Plugin for Gradle <strong>1.3.0-beta4</strong>

<p>To use data binding, Android Plugin for Gradle <strong>1.5.0-alpha1</strong>

or higher is required.</p>

<h4>Beta release</h4>

<p>To get started with Data Binding, download the library from the Support

repository in the Android SDK manager. </p>

<p>The Data Binding plugin requires Android Plugin for Gradle <strong>1.3.0-beta4

or higher</strong>, so update your build dependencies (in the top-level

<code>build.gradle</code> file) as needed.</p>

<p>Also, make sure you are using a compatible version of Android Studio.

<strong>Android Studio 1.3</strong> adds the code-completion and layout-preview

support for data binding.</p>

<p>

  <strong>Setting Up Work Environment:</strong>

</p>

<p>

  To set up your application to use data binding, add data binding to the class

  path of your top-level <code>build.gradle</code> file, right below "android".

</p>

<pre>

   dependencies {

       classpath <strong>"com.android.tools.build:gradle:1.3.0-beta4"</strong>

       classpath <strong>"com.android.databinding:dataBinder:1.0-rc1"</strong>

   }

</pre>

<p>

  Then make sure jcenter is in the repositories list for your projects in the top-level

  <code>build.gradle</code> file.

</p>

To configure your app to use data binding, add the <code>dataBinding</code> element to your

top-level <code>build.gradle</code> file with the following configuration: </p>

<pre>

allprojects {

   repositories {

       jcenter()

android {

    ....

    dataBinding {

        enabled = true

    }

}

</pre>

<p>

  In each module you want to use data binding, apply the plugin right after

  android plugin

</p>

<pre>

apply plugin: 'com.android.application'

apply plugin: 'com.android.databinding'

</pre>

<p>

  The data binding plugin is going to add necessary <strong>provided</strong>

  and <strong>compile configuration</strong> dependencies to your project.

</p>

<p>Also, make sure you are using a compatible version of Android Studio.

<strong>Android Studio 1.3</strong> adds the code-completion and layout-preview

support for data binding.</p>
