Here is my code:

 private void doFileUpload(){
            HttpURLConnection conn = null;
            DataOutputStream dos = null;
            DataInputStream inStream = null;
            String lineEnd = "\r\n";
            String twoHyphens = "--";
            String boundary =  "*****";
            int bytesRead, bytesAvailable, bufferSize;
            byte[] buffer;
            int maxBufferSize = 8*1024*1024;
            Cursor c = (MainscreenActivity.JEEMAHWDroidDB).query((MainscreenActivity.TABLE_Name), new String[] {
                     (MainscreenActivity.COL_HwdXml)}, null, null, null, null,
                              null);
             if(c.getCount()!=0){
             c.moveToLast();
             for(int i=c.getCount()-1; i>=0; i--) {
                  value=c.getString(0);           
             }
             }
            String urlString = value+"/upload_file.php";
            try
            {
             //------------------ CLIENT REQUEST

Call new loadVideo().execute(); where ever you needed.
And add the following class to do the video loading.

public class loadVideo extends AsyncTask<Void, Void, Void>
    {

        private final ProgressDialog dialog = new ProgressDialog(
                YourActivity.this);
        protected void onPreExecute() {
            this.dialog.setMessage("Loading...");
            this.dialog.setCancelable(false);
            this.dialog.show();
        }
        protected void onPostExecute(Void result) {

            if (this.dialog.isShowing()) {
                this.dialog.dismiss();
            }

                }
            });



        }

        @Override
        protected Void doInBackground(Void... params) {
 HttpURLConnection conn = null;
            DataOutputStream dos = null;
            DataInputStream inStream = null;
            String lineEnd = "\r\n";
            String twoHyphens = "--";
            String boundary =  "*****";
            int bytesRead, bytesAvailable, bufferSize;
            byte[] buffer;
            int maxBufferSize = 8*1024*1024;
            Cursor c = (MainscreenActivity.JEEMAHWDroidDB).query((MainscreenActivity.TABLE_Name), new String[] {

                              null);
             if(c.getCount()!=0){
             c.moveToLast();
             for(int i=c.getCount()-1; i>=0; i--) {
                  value=c.getString(0);
