How do I switch accounts under the NEW Google Drive Android API

Question

My authorization flow in the new Google Drive Android API is as follows:

1. Menu: SELECT ACCOUNT
2. connect();
3. onConnectionFailed() result.startResolutionForResult() invokes AccountSelectDialog / DriveAuthorization
4. onConnected() do your stuff

Works like a charm. Now repeating with the aim to switch accounts:

1. Menu: SELECT ACCOUNT
2. connect();
3. onConnected()

Here, I have no chance to get to the AccountSelectDialog since I never get onConnectionFailed() with 'result' to invoke startResolutionForResult(). What am I missing this time?

Just call

mGoogleApiClient.clearDefaultAccountAndReconnect();

have a look at the docs.

This will call the onConnectionFailed callback that will present the layout to choose among the available Google accounts:

@Override
public void onConnectionFailed(ConnectionResult connectionResult) 
{
    if (connectionResult.hasResolution()) {
        try {                                              
            connectionResult.startResolutionForResult(this, RESOLVE_CONNECTION_REQUEST_CODE);
        } catch (IntentSender.SendIntentException e) {
            // Unable to resolve, message user appropriately
        }
    } else {                                           
        GooglePlayServicesUtil.getErrorDialog(connectionResult.getErrorCode(), this, 0).show();
    }

}
