No where it’s mentioned if you want to test the Achievements and or Leaderboards if the APK can be installed locally or it needs to be downloaded from the Google Play Store specifically.
So do we need a test APK in the Alpha/Beta stage in the developer console.
or
Can I install the game locally via the Batch file to test the Achievements and Leaderboards.
I don’t think the Engine includes support for google play integration. I’d recommend downloading the SDK separately and either link it statically or as a shared lib during build.
You can test locally after setting up a game on the dashboard; it just has to be signed with the proper key. You will need to register a linked program for your debug key if you don’t want to test a “for distribution” Shipping APK locally. You do not have to upload the APK to the store to test.
