If you choose to use Google Play Services, you need to know the following :

1. To test your app when using the Google Play services SDK, you must use either:

   • A compatible Android device that runs Android 2.3 or higher and includes Google Play Store.
   • The Android emulator with an AVD that runs the Google APIs platform based on Android 4.2.2 or higher.

2. To make the Google Play services APIs available to your app:

   1. Copy the library project at <android-sdk>/extras/google/google_play_services/libproject/google-play-services_lib/ to the location where you maintain your Android app projects.
   2. Import the library project into your Eclipse workspace (if you use Eclipse) : Click File > Import, select Android > Existing Android Code into Workspace, and browse to the copy of the library project to import it.
   3. In your app project, reference Google Play services library project.

      Note: You should be referencing a copy of the library that you copied to your development workspace—you should not reference the library directly from the Android SDK directory.

   4. Use the AndroidManifest.xml written below for GooglePlayServices integration
3. To prevent ProGuard from stripping away required classes, add the following lines in the<project_directory>/proguard-project.txt file:

    

   Code Block
   language text title ProGuard
