Log
onConnectionSuspended gets called when your app gets disconnected from the Google Play services package (not necessarily the Internet). The callback gets invoked for instance when you go to Settings > Apps > Google Play services > Force Stop. Another example is when you would uninstall Google Play services. You would get onConnectionSuspended followed by onConnectionFailed after a couple of seconds (because a reconnection attempt would fail).
Also do not call mGoogleApiClient.connect() from onConnectionSuspended(...). Reconnection is handled automatically.
