      // Do nothing for now
      }

 /* startActivityForResult(Intent.createChooser(intent, "Select Picture"),
    PICK_IMAGE);
 }*/


 /**
  * Retrives the result returned from selecting image, by invoking the method
  * <code>selectImageFromGallery()</code>
  */
 @Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  super.onActivityResult(requestCode, resultCode, data);

  if (requestCode == PICK_IMAGE && resultCode == RESULT_OK
    && null != data) {
   Uri selectedImage = data.getData();
   String[] filePathColumn = { MediaStore.Images.Media.DATA };

   Cursor cursor = getContentResolver().query(selectedImage,
     filePathColumn, null, null, null);
   cursor.moveToFirst();

   int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
   String picturePath = cursor.getString(columnIndex);
   cursor.close();

   decodeFile(picturePath);

  }
