Android Google Play Games Native Samples

These samples illustrate how to use Google Play Game Services with your Android game.

  • CollectAllTheStarsNative: Demonstrates how to use the Saved Games feature to save game data. The sample signs the user in, synchronizes their data from a named game save, and then updates the UI to reflect the saved game state.

  • TrivialQuestNative: Demonstrates how to use the Events and Quests features of Google Play Game Services. The sample displays a sign-in button and four buttons to simulate killing monsters. Clicking a button generates an event, and sends it to Google Play Game Services to track what the player is doing in the game.

  • minimalist: Demonstrates a minimal use case for the Google Play Game Services API.

  • TbmpSkeletonNative: A trivial, turn-based multiplayer game. Many players can play together in this thrilling game, in which they send a shared gamestate string back and forth until someone finishes or cancels, or the second-to-last player leaves. Be the last one standing!

  • Button-Clicker: Demonstrates real-time multiplayer using invites or quickmatch

  • Teapots: Demonstrates use of the Leaderboard and Achievement APIs.

Note: In samples with corresponding counterparts for iOS and Web (particularly, CollectAllTheStars and TypeANumber), the player can play a game seamlessly across phones of different platforms. For example, you can play some levels of CollectAllTheStars on your Android device, and then pick up your iOS device and continue where you left off! TypeANumber shows your achievements and leaderboards on all platforms; when you make progress on one platform, that progress is reflected on the other devices, as well.

Pre-requisites

  1. Change the applicationId inside each individual samples build.gradle to your own package name
  2. Modify res/values/ids.xml and place your IDs there, as given by the Developer Console (create the leaderboards and achievements necessary for the sample, if any). In the Developer console, select a resource type (Achievements, Events, Leaderboards) and click "Get Resources". Copy the contents from the console and replace the contents of res/values/ids.xml.
