Custom android authenticator using Google App Engine

Question

I would like to write a custom authenticator for Android. I found this nice tutorial to do it, but instead of using Parse as authentication server, I want to use Google App Engine:

The problem is that I couldn’t find the way to do it. Do you know if that is possible?

All I can find is how to implement authentication using a Google account, but I’d rather prefer to allow users to use any email account.

Thanks.

You have plenty of choices, the first ones that come to mind:

1. You can use 3rd party OAuth providers which not all email providers are.
2. Implemment and use your own Authenticator.
3. (Recommended) Since you are not accessing user data through OAuth just implement a standard user/password authentication method using endpoints and secure the API using your android's app SHA fingersprint, as explained here
