今天想利用本地图片资源的Uri来使用ImageLoader加载图片
结果报了这么一个错误：
You should implement this support yourself (BaseImageDownloader.getStreamFromOtherSource(...))

在经过了一些博客的指点之后我总结了一下：
不同的路径有不同的方法，如果是在assets里，则在路径前加上“assets://”
还有以下情况：
String imageUri = "http://site.com/image.png"; // from Web
String imageUri = "file:///mnt/sdcard/image.png"; // from SD card
String imageUri = "content://media/external/audio/albumart/13"; // from content provider
String imageUri = "assets://image.png"; // from assets
String imageUri = "drawable://" + R.drawable.image; // from drawables (only images, non-9patch)
实例：
android如何获取一个SD卡指定文件夹的图片Uri：
String a="file://"+Environment.getExternalStorageDirectory().getPath()+"/DCIM/Camera/";
