How to submit a FQL query to Facebook on Android (thanks to http://stackoverflow.com/a/13163261/1107412)

facebookService.java

String fqlQuery = "select uid, name, pic_square, is_app_user from user where uid in (select uid2 from friend where uid1 = me())";
Bundle params = new Bundle();
params.putString("q", fqlQuery);

Session session = Session.getActiveSession();
Request request = new Request(session, 
    "/fql", 
    params, 
    HttpMethod.GET, 
    new Request.Callback(){ 
        public void onCompleted(Response response) {
        Log.i(TAG, "Got results: " + response.toString());
    }
});
Request.executeBatchAsync(request);
