android 获取assets目录下文件的路径

 String path = "file:///android_asset/icon_wm.png";

String path = null;
InputStream abpath = getClass().getResourceAsStream("/assets/icon_wm.png");
 try {
         path = new String(InputStreamToByte(abpath));
 }catch (Exception e){
        e.printStackTrace();
 }
 
private byte[] InputStreamToByte(InputStream is) throws IOException {
        ByteArrayOutputStream bytestream = new ByteArrayOutputStream();
        int ch;
        while ((ch = is.read()) != -1) {
            bytestream.write(ch);
        }
        byte imgdata[] = bytestream.toByteArray();
        bytestream.close();
        return imgdata;
    }
