GooglePlayServicesUtil.getErrorDialog is null

Google suggests (also in docs) calling getErrorDialog() if the result code is SERVICE_MISSING, SERVICE_VERSION_UPDATE_REQUIRED or SERVICE_DISABLED. So it may be that the last possible status code (SERVICE_INVALID) is what’s causing trouble.

I’m using the following code and so far it seems to work ok (testing in emulator, platform 2.3.3):

int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(activity.getApplicationContext());
if (resultCode == ConnectionResult.SUCCESS) {
    activity.selectMap();
} else if (resultCode == ConnectionResult.SERVICE_MISSING ||
           resultCode == ConnectionResult.SERVICE_VERSION_UPDATE_REQUIRED ||
           resultCode == ConnectionResult.SERVICE_DISABLED) {
    Dialog dialog = GooglePlayServicesUtil.getErrorDialog(resultCode, activity, 1);
    dialog.show();
}
