title: MapActivity could not be found. Android Studio 0.5.1
body: <p>I am setting up google map v2 in Android. I am using the new technique on adding dependency using this link."<a href="https://stackoverflow.com/questions/16624827/android-studio-with-google-play-services">Android Studio with Google Play Services</a>"</p>
  
  <p>It did nice after synchronization, clean project and rebuild project. However I could not find the MapActivity. What seems to be the problem?</p>
  
  <p>Build.gradle</p>
  
  <pre><code>apply plugin: 'android'
  
  android {
      compileSdkVersion 19
      buildToolsVersion "19.0.3"
  
      defaultConfig {
          minSdkVersion 8
          targetSdkVersion 19
          versionCode 1
          versionName "1.0"
      }
      buildTypes {
          release {
              runProguard false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
          }
      }
  }
  
  dependencies {
      compile 'com.android.support:appcompat-v7:+'
      compile fileTree(dir: 'libs', include: ['*.jar'])
      compile 'com.google.android.gms:play-services:4.2.42'
  }
  </code></pre>
