 ByteArrayOutputStream buffer = new ByteArrayOutputStream(bitmap.getWidth() * 
     bitmap.getHeight());

Doesn't hackbook example do exactly what you want?

                Bundle params = new Bundle();
                try {
                    params.putByteArray("photo",
                            Utility.scaleImage(getApplicationContext(), photoUri));
                } catch (IOException e) {
                    e.printStackTrace();
                }
                params.putString("caption", "FbAPIs Sample App photo upload");
                Utility.mAsyncRunner.request("me/photos", params, "POST",
                        new PhotoUploadListener(), null);

This may help you:

 Bundle params = new Bundle();
 try

 }
 catch (IOException e) 
 {
     e.printStackTrace();
 }
 params.putString("caption", "Through My Android Application");
 Utility.mAsyncRunner.request("me/photos", params, "POST",new PhotoUploadListener(), null);
