Graph Story Image Upload

I'm working on an Android app which lets you post a story and I want the user to upload a photo.

The app has the "publish_actions" permission and it has "user_generated", "fb:explicitly_shared".

My code is the following

ByteArrayOutputStream stream = new ByteArrayOutputStream();
    if(bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream)) {
        Log.i(TAG,"Bitmap compressed into stream successfully.");
    }

    postParams.putByteArray("image", stream.toByteArray());

    postParams.putString("user_generated", "true");
    postParams.putString(OBJECT,URL);
    postParams.putString("fb:explicitly_shared", "true");

Log.i(TAG,"Executing facebook graph story request...");

    Request request = new Request(session, "me/<appnamespace>:<action>", postParams, HttpMethod.POST, callback);
    RequestAsyncTask task = new RequestAsyncTask(request);
    task.execute();

When I check the test account timeline the story is posted, but there is no image. I suppose the problem is on this line:

postParams.putByteArray("image", stream.toByteArray());

I think the problem is either way the key is not "image" or that's not how you do it.

What's the right way to do this?

From my comment in your other question:

You can't upload an image to your me/: endpoint. You need to POST it to me/staging_resources first. See this how-to on using the Object API (specifically step 3 for image uploading).

https://developers.facebook.com/docs/howtos/androidsdk/3.0/share-using-object-api/

To add the image to your open graph action, do something like:

JSONObject obj = new JSONObject();
obj.put("url", <your staging uri here>);
obj.put("user_generated", true);
myAction.setImage(Arrays.asList(obj));
