title: How to use ActionBarActivity with Theme.Material
body: <p>I created a new project targeting the L preview. The starter activity that the sdk generates extends ActionBarActivity, however, when I try to run the bare-bone generated activity, it throws the following exception:</p>
  
  <pre><code>  Caused by: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.
              at android.support.v7.app.ActionBarActivityDelegate.onCreate(ActionBarActivityDelegate.java:110)
              at android.support.v7.app.ActionBarActivityDelegateICS.onCreate(ActionBarActivityDelegateICS.java:57)
              at android.support.v7.app.ActionBarActivity.onCreate(ActionBarActivity.java:99)
  </code></pre>
  
  <p>I've looked around but <code>Theme.AppCompat.Material</code> doesn't seem to exist. How do I make ActionBarActivity to take advantage of the new Material themes?</p>
  
  <p>My build.gradle:</p>
  
  <pre><code>apply plugin: 'com.android.application'
  
  android {
      compileSdkVersion 'android-L'
      buildToolsVersion '20.0.0'
      defaultConfig {
          applicationId 'com.sdchang.example'
          minSdkVersion 'L'
          targetSdkVersion 'L'
          versionCode 1
          versionName '1.0'
      }
      buildTypes {
          release {
              runProguard false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
      }
      productFlavors {
      }
  }
  
  dependencies {
      compile fileTree(dir: 'libs', include: ['*.jar'])
      compile 'com.android.support:appcompat-v7:21.+'
      compile 'com.mcxiaoke.volley:library:1.0.+@aar'
      compile 'com.google.code.gson:gson:2.2.+'
      compile 'com.squareup.okhttp:okhttp:2.0.+'
  }
  </code></pre>
