I get the following error:

请参考错误行（Gradle）：

调用类:
CustomMultipartRequest req = new CustomMultipartRequest(URL, //url where you want to send the multipart request
elistener, //instance of onErrorResponse Listener
rlistener, //instance of onResponse Listener
entityBuilder);
req.setShouldCache(false);
RequestQueue rq = Volley.newRequestQueue(context);
rq.add(req);
你能帮我解决这个错误吗？
提前感谢；）
