Android: Http post with parameters not working -

i need create http post request parameters. know there many examples out there, have tried using httpparams, namevaluepair etc cant seem correct format server.

server type: rest based api utilizing json data transfer
content-type: application/json
accept: application/json
content-length: 47
{"username":"abcd","password":"1234"}

i can pass these headers cant seem pass these params "username","password". here code:

    httpclient client = new defaulthttpclient();       httppost post = new httppost("http://www.mymi5.net/api/auth/login");        list<namevaluepair> pairs = new arraylist<namevaluepair>();       pairs.add(new basicnamevaluepair("username","abcd"));       pairs.add(new basicnamevaluepair("password","1234"));       post.setheader("content-type", "application/json");     post.setheader("accept", "application/json");     urlencodedformentity entity = new urlencodedformentity(pairs,"utf-8");       post.setentity(entity);       httpresponse response = client.execute(post);   

i tried debug, cant see if entity attached or not... doing wrong?
