TbmpSkeletonNative: The sample demonstrates how to use turn-based multiplayer gaming feature with C++ code with Google Play game services native SDK. A trivial turn-based-multiplayer game. In this thrilling game, you can invite many friends, then send a shared gamestate string back and forth until someone finishes, cancels, or the second-to-last player leaves. The sample is compatible to Android, iOS SkeletonTbmp sample, you can enjoy cross platform play between them.

1. Set up the project in Developer Console. For more info:

   https://developers.google.com/games/services/console/enabling

   Note your package name and the APP ID of the project.

2. Enable Turn-based multiplayer setting in MULTIPLAYER SETTINGS (see the ones that the sample needs in its res/values/ids.xml)

1. Start Eclipse
2. Import the Google Play Services library project (available for download through the SDK manager):
   1. Click File | Import | Android | Existing Android Code into Workspace
   2. Select SDK/extras/google/google_play_services/google_play_services_lib (where SDK stands for the path where you installed your Android SDK)
   3. Click Finish
3. Import the sample
4. Go into the project properties window for that project (right-click, Properties) and check that this project has a reference to the google_play_services_lib project.

Your project should now compile. However, don't run it yet, since you still need to adjust your game's IDs in order for the sample(s) to work.

Now jump to the Modify IDs, compile and run section and continue to follow the instructions there.

To set up a sample:

1. Change the package name from com.google.example.games.* to your own package name (the same one you registered in Developer Console!). To do that, open AndroidManifest.xml and put your package name in the "package" attribute of the manifest tag. You will need to fix some of the references (particularly to the generated R class) because of the package name change. Ctrl+Shift+O in Eclipse (and Alt+Enter in Android Studio) should take care of most of the work.
2. Modify res/values/strings.xml and place your IDs there, as given by the Developer Console (create the leaderboards and achievements necessary for the sample, if any). Remember that the App ID is only the numerical portion of your client ID, so use 123456789012 and not 123456789012.apps.gooogleusercontent.com.
3. Compile and run.

IMPORTANT: make sure to sign your apk with the same certificate as the one whose fingerprint you configured on Developer Console, otherwise you will see errors.

IMPORTANT: if you are testing an unpublished game, make sure that the account you intend to sign in with (the account on the test device) is listed as a tester in the project on your Developer Console setup (check the list in the "Testing" section), otherwise the server will act as though your project did not exist and return errors.
