    final int THUMBNAIL_SIZE = 64;
    //InputStream is=getAssets().open("apple-android-battle.jpg");
    FileInputStream fis = new FileInputStream("/sdcard/apple.jpg");
    Bitmap imageBitmap = BitmapFactory.decodeStream(fis);

    Float width = new Float(imageBitmap.getWidth());
    Float height = new Float(imageBitmap.getHeight());
    Float ratio = width/height;
    imageBitmap = Bitmap.createScaledBitmap(imageBitmap, (int)(THUMBNAIL_SIZE * ratio), THUMBNAIL_SIZE, false);

    ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
    imageBitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
    imageData = baos.toByteArray();
    im.setImageBitmap(imageBitmap);
