gistfile1.txt

    Bitmap bitmap = loadBitmapAsset("my_nine_patch_image.9.png", this);

    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    bitmap.compress(CompressFormat.PNG, 0 /* ignored for PNG */, bos);
    byte[] bitmapdata = bos.toByteArray();
    ByteArrayInputStream bs = new ByteArrayInputStream(bitmapdata);

    BitmapFactory.Options options = new BitmapFactory.Options();
    options.inSampleSize = 2;
    Bitmap preview_bitmap = BitmapFactory.decodeStream(bs, null, options);

    NinePatchDrawable drawable = NinePatchBitmapFactory
        .createNinePatchDrawable(getResources(), preview_bitmap);//bitmap will be fine.
    mTarget.setBackgroundDrawable(drawable);
