In this example uploading an image from sdcard to web server.

      2.  place sdcard image path and image name in UploadToServer.java. ( see below )
      3.  create a php script (UploadToServer.php) at server. ( see below )
      4.  place php script path in UploadToServer.java. ( see below )
      5.  create folder name uploads on server where you have placed php script.
      6.  give permission 777 (read/write/execute) to uploads folder.
