[android help] how to access resources in a android library project

I am building an android library project which need some static resources(images/xml and etc) internally.

Then I wonder where I can put these resources and how to access them?

Since I put the resources in the assets folder. And I use the AssetManager to access the resources:

    AssetManager am = Resources.getSystem().getAssets();
    InputStream is;
    try {
        is = am.open("t.jpg");
        Drawable dw = Drawable.createFromStream(is, null);
        Bitmap bm = ((BitmapDrawable) dw).getBitmap();
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bm.compress(Bitmap.CompressFormat.JPEG, 100, stream);
    } catch (IOException e) {
        e.printStackTrace();
    }

However I got the error: W/System.err(19583): java.io.FileNotFoundException: t.jpg

What is the problem?
