單擊從谷歌登錄登出時的Android強制停止。單擊從谷歌登錄登出時的Android強制停止
時，在註銷按鈕我的應用程序的用戶點擊，然後我打電話功能confirmationbox，如果用戶點擊ya或ok所以用戶將註銷，但現在它強制停止當用戶點擊ya或ok
這是我的代碼
private void confirmationBox() {
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Apakah Anda Yakin?")
.setCancelable(false)
.setPositiveButton("Ya", new DialogInterface.OnClickListener() {
public void onClick(@SuppressWarnings("unused") final DialogInterface dialog, @SuppressWarnings("unused") final int id) {
Auth.GoogleSignInApi.revokeAccess(mGoogleApiClient).setResultCallback(
new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
}
});
session.logoutUser();
Intent intent = new Intent(getApplicationContext(),LoginActivity.class);
startActivity(intent);
finish();
}
})
.setNegativeButton("Tidak", new DialogInterface.OnClickListener() {
public void onClick(final DialogInterface dialog, @SuppressWarnings("unused") final int id) {
dialog.cancel();
}
});
final AlertDialog alert = builder.create();
alert.show();
}
GoogleSignInOption
private void setGoogleSignInAccount() {
// Configure sign-in to request the user's ID, email address, and basic profile. ID and basic profile are included in DEFAULT_SIGN_IN.
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.build();
// Build a GoogleApiClient with access to the Google Sign-In API and the options specified by gso.
mGoogleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
