Using AuthenticatorActivity as application signin

Question

My app requires a sync adapter and therefore requires some authentication to take place before an account can be added to the Accounts & Sync.

I have followed the sample sync adapter app and have my app setup. I can for instance now verify a user on my server and have an account added to the Accounts & Sync section.

The thing is I would prefer this precedure of adding an account via the AuthenticatorActivity to take place inside my app for a better user experience.

So far I have added the AuthenticatorActivity when my app launches. As soon as authentication is successful it launches the Accounts & Sync settings section which completely ruins the applications signin/signup experience.

How can I stop this behaviour (launch of the Accounts & Sync setting on success) and allow my app to move to my next chosen step?

It is relatively simple procedure:

Make sure instead of using startActivity you use startActivityForResult.

Intent intent = new Intent(this, ClassYouAreLaunching.class);
startActivityForResult(intent, 0); // 0 reflects the requestCode seen in onActivityResult

Then you make sure you can capture the intent once it is sent back to you from the origin intent.

onActivityResult(int requestCode, int resultCode, Intent intent) {

    if( resultCode == Activity.RESULT_CANCELED ) {

        finish();
    } else {
        // MAYBE        
        switch( requestCode ) {
            ...     

        }
    }

}
