everything can get.here code.

 private callbackmanager callbackmanager;  private loginbutton loginbutton;    in oncreate(){    loginbutton = (loginbutton) findviewbyid(r.id.login_button);    // don't forget give this.     loginbutton.setreadpermissions(arrays.aslist("public_profile,email,user_birthday"));       loginbutton.setonclicklistener(new view.onclicklistener() {        @override       public void onclick(view v) {         getdetails();       }      });       }   private void getdetails() { //for facebook // facebooksdk.sdkinitialize(getapplicationcontext());  callbackmanager = callbackmanager.factory.create(); //register callback object facebook result   loginmanager.getinstance().registercallback(callbackmanager, new facebookcallback<loginresult>() {             @override             public void onsuccess(loginresult loginresult) {                  graphrequest request = graphrequest.newmerequest(accesstoken.getcurrentaccesstoken(),                         new graphrequest.graphjsonobjectcallback() {                             @override                             public void oncompleted(jsonobject jsonobject, graphresponse graphresponse) {                                 try {                                     profile profile = profile.getcurrentprofile();                                     if (profile != null) {                                        string facebook_id = profile.getid();                                         string f_name = profile.getfirstname();                                        string l_name = profile.getlastname();                                         profile_image = profile.getprofilepictureuri(400, 400).tostring();                                     }                                    string email_id = jsonobject.getstring("email"); //email id                                 } catch (jsonexception e) {                                     logger.logerror(e);                                 }                             }                          });
