For my App I need to have a List sync with Google Drive. I have already implemented the SignIn and had my Main_Activity implement both:
com.google.android.gms.common.api.GoogleApiClient.ConnectionCallbacks,
com.google.android.gms.common.api.GoogleApiClient.OnConnectionFailedListener
Even though I read the whole Google Drive API for Android documentation, and more specifically the Store Application Data part. And looked through the example on GitHub, I wasn't able to get it to work. I personally think that this documentation is really confusing to read. It's not even clear what is the difference between the Google Drive API for android and the Google Drive REST API, and which one I should use for my scenario.
Also I noticed that the example on GitHub extends a custom Activity that has other methods in it.
Can any of you explain step by step how to use the android drive API?
