You can get Image size by file.length() method

protected void onActivityResult(int requestCode, int resultCode, Intent data)  {
   super.onActivityResult(requestCode, resultCode, data);
   if(requestCode==RESULT_LOADIMAGE&&resultCode==RESULT_OK&&null!=data)
    Uri selectedImages=data.getData();
    String[] filePathColon={MediaStore.Images.Media.DATA};
    Cursor cursr=getContentResolver().query(selectedImages, filePathColon, null, null, null);
    cursr.moveToFirst();
    int columnindex=cursr.getColumnIndex(filePathColon[0]);
    String picturepath=cursr.getString(columnindex);
    cursr.close();
    long size = new File(picturepath).length();//where size in bytes
  }

Now you can convert it on KB or MB as you want.
