I am trying to upload one image on facebook wall from drawable folder of my android project. But I am failed … the message is showing on the wall but image is not on wall ..
my sample code is given below ..

    Drawable drawable =  ClassName.this.getResources().getDrawable(R.drawable.ic_launcher);
        Bitmap bitmap = (Bitmap)((BitmapDrawable) drawable).getBitmap();
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
        byte[] bitMapData = stream.toByteArray();


        Bundle params = new Bundle();

        params.putString("message", "Tarun Kumar");
        params.putString("name", "MY Image");
        params.putByteArray("picture", bitMapData);
        mAsyncFbRunner.request("me/feed", params, "POST", new WallPostListener());

It is showing some error on Log.. like

Answer 1

In case of posting image from app to fb you can’t use me/feed parameter , you have to use photos and request will be

mAsyncFbRunner.request("photos", parameters, 
                                    "POST", new WallPostListener());
