【安卓笔记】res/raw与assets区别

Bitmap bitmap = BitmapFactory.decodeResource(this.getResources(),R.raw.demo);
            iv_show.setImageBitmap(bitmap);
            bitmap = null;

InputStream is = this.getResources().openRawResource(R.raw.demo);
            Bitmap image = BitmapFactory.decodeStream(is);
            iv_show.setImageBitmap(image);
            image = null;

AssetManager manager = this.getAssets();
            try
            {
                InputStream in = manager.open("image/image.jpg");//注意路径
                Bitmap bitmap = BitmapFactory.decodeStream(in);
                iv_show.setImageBitmap(bitmap);
                bitmap = null;
                System.gc();
            } catch (IOException e)
            {
                e.printStackTrace();
            }
