TRIVIAL DRIVE - SAMPLE FOR IN-APP BILLING VERSION 3 Copyright (c) 2012 Google Inc. All rights reserved. Bruno Oliveira, 2012-11-29 This sample can't be run as-is. You have to create your own application instance in the Developer Console and modify this sample to point to it. Here is what you must do: ON THE GOOGLE PLAY DEVELOPER CONSOLE: 1. Create an application on the Developer Console. You must use version 2, available at https://play.google.com/apps/publish/v2/ or later. In-app billing version 3 is not available in the older versions of Developer Console. 2. In that app, create MANAGED in-app items with these IDs: premium, gas Set their prices to 1 dollar (or any other price you like, but make it a small price since this is just for testing purposes). 3. Make sure your test account (the one you will use to test purchases) is correctly listed in the "testing" section. Your test account CANNOT BE THE SAME AS THE PUBLISHER ACCOUNT. If it is, purchases won't go through. 4. Grab the application's public key (a base-64 string) -- you will need that next. Note that this is the *application's* public key, not the developer public key. You can find the application's public key in the "Services & API" page for your application. IN THE CODE 5. Open MainActivity.java and replace the placeholder key with your app's public key. 6. Change the sample's package name to your package name (you can do that using your favorite IDE's refactoring feature, or manually by changing the code directories and package declarations in .java files) 7. Don't forget to update the package name in AndroidManifest.xml. Many refactoring tools fail to do that automatically! 8. Make sure that AndroidManifest.xml lists the updated package name! 9. Export an APK, signing it with your PRODUCTION (not debug) developer certificate BACK TO GOOGLE PLAY DEVELOPER CONSOLE 10. Upload your APK to Google Play 11. Wait 2-3 hours for Google Play to process the APK (if you don't, you might see errors where Google Play says that "this version of the application is not enabled for in-app billing" or something similar) TEST THE CODE 12. Install the APK, signed with your PRODUCTION certificate, to a test device [*] 13. Run the app 14. Make purchases (make sure you're purchasing with an account that's NOT your developer account with which you uploaded the app to Google Play). Remember to refund any real purchases you make, if you don't want the charges to actually to through. [*]: it will be easier to use a test device that doesn't have your developer account logged in; this is because, if you attempt to purchase an in-app item using the same account that you used to publish the app, the purchase will not go through.
