OnActivityResult non chiamato dopo startIntentSenderForResult

Question

Sto utilizzando una pagina di avvio per "Accedi con Google". Quando l'utente ha più account ... dopo aver selezionato l'account con cui desiderano accedere, sto tentando di avviare l'attività principale delle app, ma per qualche motivo lo onActivityResult non viene mai chiamato nel mio frammento.

Im the Activity, chiamo onActivityResult e lo faccio chiamare super in modo che il frammento possa gestirlo, ma non spara mai.

Qualche suggerimento?

Ecco il frammento che è in questione:

Answer 1

La chiave era chiamare il metodo seguente nella prima attività.

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
} 

Answer 2

Per risolvere correttamente il problema È possibile utilizzare già preparato soluzione accountPicker.
Tuttavia - Se si vuole mettere a punto una soluzione personalizzata - Un'idea è quella di iniziare la vostra seconda attività (dalla prima attività, ovviamente) con:

Intent intent = this.getIntent(); 
intent.putExtra(... /* some code that will control second activity */ 
startActivityForResult(intent, request_code); 

e poi, quando l'attività ha fatto tutto quello che doveva fare si permettono di ritorno:

Intent intent = this.getIntent(); 
intent.putExtra(... /* all needed results to return */); 
this.setResult(RESULT_OK, intent); 
finish(); 

finalmente è la tua prima attività che quindi ottiene risultato nel suo onActivityResult.

Answer 3

Aggiungere questo nella vostra attività esterna:

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.change_to_your_id); 
    fragment.onActivityResult(requestCode, resultCode, data); 
}
