在`finish()`之后没有调用onActivityResult - 调用被调用的活动

Question

I know, I know... This problem is all over SO already. None of those solutions worked for me / applied to me.

Here is how I try to do it.

From LoginActivity (Calling Activity ):

    private void loginSuccessful(LoggedInUserView model) {
        String welcome = String.format(getString(R.string.welcome), model.getDisplayName());
        Toast.makeText(getApplicationContext(), welcome, Toast.LENGTH_LONG).show();
        Intent intent = new Intent(this, PinCodeActivity.class);
        if (!model.isNewUser()) {
            intent.putExtra("prompt", "Enter your pin");
            startActivityForResult(intent, 102);
        } else {
            intent.putExtra("prompt", "Enter a pin");
            startActivityForResult(intent, 103);
        }
    }

Then in PinCodeActivity (Called Activity )

    private void handlePinEntered() {
        Intent intent = new Intent();
        intent.putExtra("hash", pin.getValue());
        setResult(Activity.RESULT_OK, intent);
        System.out.println("==================================="); // Is printed
        finish();
    }

Then LoginActivity.onActivityResult() EDIT: idk if important but it doesn't matter in my case whether super.onActivityResult() is called first or last. They both result in the same.

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        System.out.println(requestCode); // Is NOT printed
        if (resultCode == Activity.RESULT_OK)
            switch (requestCode) {
                case 101:
                    try {
                        // The Task returned from this call is always completed, no need to attach
                        // a listener.
                        Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
                        GoogleSignInAccount account = task.getResult(ApiException.class);
                        loginViewModel.login(account);
                    } catch (ApiException e) {
                        // The ApiException status code indicates the detailed failure reason.
                        Log.w(TAG, "signInResult:failed code=" + e.getStatusCode());
                    }
                    break;
                case 102:
                    System.out.println(data.getStringExtra("hash"));
                    break;
                case 103:
                    System.out.println(data.getStringExtra("hash"));
                    break;
            }
        super.onActivityResult(requestCode, resultCode, data);
    }

This is how LoginActivity is defined

public class LoginActivity extends AppCompatActivity {

    private static final String TAG = "LOGIN";

    @Inject
    DaggerViewModelFactory viewModelFactory;
    @Inject
    AppProperties appProperties;
    private LoginViewModel loginViewModel;

    private ProgressBar loadingProgressBar;

    private EditText usernameEditText;
    private EditText passwordEditText;

    private Button loginButton;
    private SignInButton googleLoginButton;
    private GoogleSignInClient googleSignInClient;
// more code...
}

And finally how PinCodeActivity is defined

public class PinCodeActivity extends AppCompatActivity implements View.OnClickListener {
    private List<RadioButton> unchecked;
    private List<RadioButton> checked = new LinkedList<>();
    private PinCode pin = new PinCode();
// more code...
}

Here is the logcat

2019-11-09 19:26:08.000 2462-2535/com.example.finance D/EGL_emulation: eglMakeCurrent: 0x7fb761429ae0: ver 3 0 (tinfo 0x7fb761418f40)
2019-11-09 19:26:08.009 2462-2535/com.example.finance D/EGL_emulation: eglMakeCurrent: 0x7fb761429ae0: ver 3 0 (tinfo 0x7fb761418f40)
2019-11-09 19:26:10.506 2462-2462/com.example.finance I/System.out: ===================================
2019-11-09 19:26:11.069 2462-2535/com.example.finance D/EGL_emulation: eglMakeCurrent: 0x7fb761429ae0: ver 3 0 (tinfo 0x7fb761418f40)

Note the line with all the === which is printed right before finish() and right after setResult() this means it was able to set the result. Also I don't see signs of errors/crashes looking at those logs.

Answer 1

My problem is as the title says, onActivityResult() is not called from activity that I started with startActivityForResult()

Maybe it's just the way you phrased that, but your code doesn't clarify, so let's be clear. onActivityResult() should NOT be called "from activity that [you] started". onActivityResult is called in the activity that you originally called startActivityForResult from .

So your onActivityResult should be declared in LogInActivity NOT in PinCodeActivity .

Hope that helps!
