2. connect();
3. onConnectionFailed() result.startRe

Answer 1

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();
    }

}
