ActivityResultLauncher pass custom requestcode

Question

I've got a simple ActivityResultLauncher implementation, where I can select an image from the gallery:

ActivityResultLauncher<Intent> actResLauncher;
actResLauncher = registerForActivityResult(   new ActivityResultContracts.StartActivityForResult(),this);
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
actResLauncher.launch(intent);

And the result:

@Override
public void onActivityResult(ActivityResult  result) {
    if(result.getResultCode()== Activity.RESULT_OK){

    }
}

The issue is with this code is that I rely on the predefined Resultcodes like Activity.RESULT_OK or Activity.RESULT_CANCELED. Is there a way to pass custom Requestcodes when launching the intent?

First of all, you do not need onActivityResult(). That way was old. You now have launchers for specific purposes. So no more request codes You now do it like below. Create a function like this:

ActivityResultLauncher<String> imageActivityResultLauncher = registerForActivityResult(
            new ActivityResultContracts.GetContent(),
            uri -> 
               //do something with uri
            });

And then wherever you want to launch this, just write:

imageActivityResultLauncher.launch("image/*");
