Hope this helps example here using android handlers queues and runnables to upload 63 80K files to a cloud service in 3 seconds. The code uses apache httpclient threadpools and a technique for parallelizing and enqueing http requests covered here
Those ideas can be adapted to a service that can post runnables to a queue.

will be helpful for those in need Each file element must have a unique name, or use PHP's array shorthand:
code :
<input type="file" name="file1" />
<input type="file" name="file2" />
<input type="file" name="file[]" />
<input type="file" name="file[]" />
$_FILES = array(
    'fieldname' => array(
         'name' => array(
             0 => 'first file',
             1 => 'second file',

Does that help Edit: solved, scroll down ;) , Look at this bit of code:
code :
protected void onProgressUpdate(Integer... progress) {
    dialog.setProgress((int) (progress[0]));
     int progress_done=20;
     for (images_cursor.moveToFirst(); !images_cursor.isAfterLast(); images_cursor.moveToNext()) {


            //Get image and convert to byte array
            byte[] image_ba = images_cursor.getBlob(images_cursor.getColumnIndex("image"));
            long image_unit_id = images_cursor.getLong(images_cursor.getColumnIndex("unit_id"));
            String image_caption = images_cursor.getString(images_cursor.getColumnIndex("caption"));

            //add image to multipart
            entity.addPart("image" + counter, new ByteArrayBody(image_ba, "image" + counter + ".jpg"));

            //add unit _id to multipart
            entity.addPart("image_unit_id" + counter, new StringBody(String.valueOf(image_unit_id)));

            //add caption to multipart
            entity.addPart("image_caption" + counter, new StringBody(String.valueOf(image_caption)));

fixed the issue. Will look into that further Mistake lies where filePath is nulled. As Async task runs in background, so equating filePath to null gives file not found exception. Some sort of delay must be provided after new UploadFileToServer().execute(); to let the file upload complete and then load next file. Works!!!!!

wish help you to fix your issue File title is not unique in Drive API. However you can save the IDs of your newly created files in your app's local storage, so you can check against the IDs in the Drive side when you want to upload the file again.
You can use the CreateFileActvity.java from the Google Drive Demo GitHub page. It will return a file ID after you create a file successfully, so you can store the ID in your local storage.
