Calling new activity after facebook login | Android -

i have 2 activities in android application. on first one, ask user login facebook. after user logs in, collect user data such email, name , call new activity passing these parameters it. below facebook authorize method:

 public void loginfb(final view v)     {                    facebook.authorize(this, new string[] { "email", "read_stream" }, new dialoglistener() {              @override             public void oncomplete(bundle values) {                 this.getlogininfo(v);             }             private void getlogininfo(view v) {                 // todo auto-generated method stub                 logininfo(v);                                }              @override             public void onfacebookerror(facebookerror error) {}              @override             public void onerror(dialogerror e) {}              @override             public void oncancel() {}      });                 } 

below logininfo() method:

public void logininfo(final view v){     masyncrunner.request("me", new requestlistener(){             @override         public void oncomplete(string response, object state) {             try{                 log.d("profile", response.tostring());                 jsonobject json = util.parsejson(response);                 final string fname1 = json.getstring("first_name");                 final string lname1 = json.getstring("last_name");                 final string email = json.getstring("email");                  intent fblogged = new intent();                 bundle passdata = new bundle();                 passdata.putstring("fname", fname1);                 passdata.putstring("lname", lname1);                 passdata.putstring("email", email);                 fblogged.putextras(passdata);                 fblogged.setclass(v.getcontext(), requestfb.class);                 startactivity(fblogged);                 }             catch(jsonexception e){                 log.w("this", "eror");             }                        }             @override         public void onioexception(ioexception e, object state) {             // todo auto-generated method stub          }          @override         public void onfilenotfoundexception(filenotfoundexception e,                 object state) {             // todo auto-generated method stub          }          @override         public void onmalformedurlexception(malformedurlexception e,                 object state) {             // todo auto-generated method stub          }          @override         public void onfacebookerror(facebookerror e, object state) {             // todo auto-generated method stub          }                });   }      

so, new activity starting on oncomplete() of getting user data.

this works perfectly, when user clicks login, , logs in facebook, first activity page remains on screen few seconds , next activity called. there lag. how can fix lag? when user clicks login , after login authorized, should take user directly second activity. suggestions?

thanks!

it's simple, running fb graph request in new thread (using asyncrunner) when request completed start new activity , that's why "lag".

you should run graph request in new activity instead of first one, like:

public void loginfb(final view v) {     facebook.authorize(this, new string[] { "email", "read_stream" }, new dialoglistener() {         @override         public void oncomplete(bundle values) {             intent fblogged = new intent(v.getcontext(), requestfb.class);             startactivity(fblogged);         }          @override         public void onfacebookerror(facebookerror error) {}          @override         public void onerror(dialogerror e) {}          @override         public void oncancel() {}     }); }  public class requestfb extend activity {     protected void oncreate(bundle savedinstancestate) {         facebook facebook = new facebook("your_app_id");         asyncfacebookrunner asyncrunner = new asyncfacebookrunner(facebook);          asyncrunner.request("me", new requestlistener(){             try {                 final jsonobject json = util.parsejson(response);                 final string fname1 = json.getstring("first_name");                 final string lname1 = json.getstring("last_name");                 final string email = json.getstring("email");                  runonuithread(new runnable() {                     public void run() {                         // use data                     }                 });             }             catch(jsonexception e) {                 log.w("this", "eror");             }         });      } }
