i am using android volley framework for sending jsonobject request to my server.get request is working fine.now i would like to send a post request with request parameters which is nested hashmap< string,object >.i override the getparams method but it expects me to send hashmap< string,string >.

there is any way to pass hashmap as request parameter?

i have followed this link [enter link description here](http://www.androidhive.info/2014/05/android-working-with-volley-library-1/)
