android app: load a local image into texture by WWW class

HELLO!

i make a android app that have to load a local image into texture.i can use WWW to load a url,but i can't use WWW to load a URi....

i use the following code to get android URi,and add my own intent fiter(action_send).when user open album,he can share the image to my app:

AndroidJavaObject activity = new AndroidJavaClass("com.unity3d.player.UnityPlayer").GetStatic("currentActivity");

AndroidJavaClass sintent = new AndroidJavaClass("android.content.Intent"); AndroidJavaObject intent = activity.Call("getIntent");

AndroidJavaObject uri = intent.Call("getParcelableExtra",sintent.GetStatic("EXTRA_STREAM"));

string appURL = uri.Call("toString");

i can receive a link like this:

content://media/external/images/media/47

but it seem that the WWW class don't know what is it.....

===edited====

i try to view the image Detail inside album,the image path is something like this:

/storage/sdcard0/Download/XXXXXX.JPG

i try to type this in to load the image: url="file://storage/sdcard0/Download/XXXXXX.JPG"; WWW www = new WWW(url); yield return www; plane.renderer.material.mainTexture = www.texture;

it still not working.....

and two type of link look very different:

file://storage/sdcard0/XXXXXXX.jpg content://media/external/images/media/47

but none of them work...........
