How to start Activity for result from IME

Question

I'm developing an app that should return some text to the app that started the intent.

But the app that starts the intent is a IME/soft Keyboard. So StartActivityForResult is not available because an IME is a service.

How can I achieve this?

What I got so far:

Keyboard:

final Intent intent = new Intent("com.example.helloworld.GETTEXT");
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
intent.putExtra("keyboard", true);
startActivity(intent);

Other App:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Bundle extras = getIntent().getExtras();
    if (extras == null){                
        return;
    } else {
        finish();
    }
}

@Override
public void finish() {
    Intent data = new Intent();
    data.putExtra("test", "PASSED");
    setResult(RESULT_OK, data);
    super.finish();
}

Answer 1

You can use ResultReceiver. Look at this example, it's pretty clear explains how it works.

Answer 2

You could use a ResultReceiver for this is think.

ResultReceiver lReceiver = new KeyboardResultReceiver(aListener);
final Intent intent = new Intent("com.example.helloworld.GETTEXT");
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_MULTIPLE_TASK);
intent.putExtra(EXTRA_RESULT_RECIEVER, lReceiver);
intent.putExtra("keyboard", true);
startActivity(intent);

private static final class KeyboardResultReceiver extends ResultReceiver {

    public FileUploadResultReceiver() {
    }

    @Override
    protected void onReceiveResult(int aResultCode, Bundle aResultData) {
            //Do your thing here you can also use the bundle for your data transmission
    }
}
