Upload multiple images with Android



I am using following code to upload multiple images to Twitter and get the media_ids as response:

   for (int i = 0; i < list_image_paths.size(); i++) {
        Log.i("UPLOAD_CHECKER", "image-> " + list_image_paths.get(i));
        //get imagepath and create file
        String image_path = list_image_paths.get(i);
        File imagefile = new File(image_path);
        RequestBody file = RequestBody.create(MediaType.parse("image/*"), imagefile);

        //start upload
        mediaservice.upload(file, null, null).enqueue(new Callback<Media>() {
            public void success(Result<Media> result) {
                //Log.e("UPLOAD_CHECKER", "result ID: " + result.data.mediaId);
                // media_ids = result.data.mediaIdString;
                String got_media_id = result.data.mediaIdString;
                Log.e("UPLOAD_CHECKER", "media_id: " + got_media_id);

            public void failure(TwitterException e) {
                Log.e("UPLOAD_CHECKER", "error uploading image: " + e.toString());


Currently I am using


so I guess results are summerized before responding. But how can I start uploading and getting response for every for loop iteration? I saw that I can use .execute method but I could not implement it right…
