How can I receive CameraActivities result in a DIFFERENT Activity (i.e. not in the launching one)?

Question

Hi,

I hope the title says it all: I've got Activity A which fires up the Camera intent via:

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, REQUEST_CAMERA);

After the picture is taken I can easily grab the picture in:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)

But I'd like to receive the result in Activity B in which the image can be edited. Right now I'm receiving the result in Activity A and pass it over to Activity B which results in showing the GUI of Activity A for a short while:

Intent i = new Intent().setAction("DisplayJPEG");
i.setClass(this, EditImageActivity.class);
i.putExtra("IMAGE_URI", uri);
startActivityForResult(i, REQUEST_EDIT_IMAGE);

Of course, I will need the result from Activity B in Activity A after the image has been edited. But that should work with:

setResult(resultCode, data);

So there has to be a way to do what I need. Please point me into the right direction.

Thanks in advance, steff

Answer 1

Have you tried launching ActivityB, and in ActivityB onCreate event launch the Camera Intent?

Answer 2

You technically can't do what you're asking. You'll need to find a way to continue passing it the way you are and hide the UI or do as Pentium says and do it the other way around.

Answer 3

Edit: Nevermind, I misread how this works. What actually happens is you can use Activity A to start Activity B for result, but then if Activity B needs to start Activity C to continue processing whatever Activity A wanted, you can use FLAG_ACTIVITY_FORWARD_RESULT to make Activity C return its result to Activity A not B.

I haven't looked into this more than a quick glance, but I noticed an Intent flag called FLAG_ACTIVITY_FORWARD_RESULT which according to the documentation:

If set and this intent is being used to launch a new activity from an existing one, then the reply target of the existing activity will be transfered to the new activity. This way the new activity can call setResult(int) and have that result sent back to the reply target of the original activity.

Like I said, I haven't experimented with this, but that seems to suggest that you could launch your camera intent from Activity A but have it forward its result to Activity B.
