Ciao io uso il login di Google nella mia app funziona, ma ogni volta che mi disconnetto ho provato molte soluzioni per la disconnessione ma non funziona per me e se faccio altri clic sul pulsante di accesso Google, l'app si arresta in modo anomalo.Errore nel re-login con Google dopo il logout su Android
Ecco il mio codice di accesso
public class LoginActivity extends Activity implements AsyncInterface,

Questo metodo non funziona per me. Anche se cancello la preferenza e provo per un nuovo accesso con google, l'app si blocca.
Logcat errore
java.lang.NullPointerException: Attempt to invoke virtual method 'boolean com.google.android.gms.common.ConnectionResult.hasResolution()' on a null object reference
Grazie per la risposta. Ma non funziona per me. Penso che se uso altre attività per effettuare il logout, ecco perché succede. Ho aggiornato il mio codice di logout con tutta l'attività in cui applico il tuo codice ... Va bene? – Sam
sì va bene ... –
Ma non funziona per me, ogni volta che clicco sul pulsante di accesso dopo il logout, l'app si blocca con l'errore sopra definito ... – Sam
