i followed proper documentation of facebook used code generate sha key , placed on console disable sand box enable face book login disable deep linking still no luck code used face book following

facebookbtn.setonclicklistener(new view.onclicklistener() {          @override         public void onclick(view arg0) {             // todo auto-generated method stub             session.openactivesession(signin_rewards.this, true, new session.statuscallback() {                  // callback when session changes state                 @override                 public void call(session session, sessionstate state,                         exception exception) {                      log.v("log_tag", "token=" + session.getaccesstoken());                     log.v("log_tag", "token=" + session.isopened());                      session currentsession = session.getactivesession();                      if (currentsession == null || currentsession.getstate().isclosed())                      {                          session = new session.builder(signin_rewards.this).build();                         session.setactivesession(session);                         currentsession = session;                     }                       else if(!currentsession.isopened())                     {                         //ask username , password                         openrequest op = new session.openrequest(signin_rewards.this);                          op.setloginbehavior(sessionloginbehavior.sso_with_fallback);                         op.setcallback(null);                          list<string> permissions = new arraylist<string>();                         permissions.add("publish_stream");                         permissions.add("user_likes");                         permissions.add("email");                         permissions.add("user_birthday");                         permissions.add("user_location");                         op.setpermissions(permissions);                           session = new session.builder(signin_rewards.this).build();                         session.setactivesession(session);                         session.openforpublish(op);                     }                     else if (session.isopened()) {                             // make request /me api                         request.executemerequestasync(session,                                 new request.graphusercallback() {                                      // callback after graph api response user                                     // object                                     @override                                     public void oncompleted(graphuser user,                                             response response) {                                         if (user != null) {                                            /* textview welcome = (textview) findviewbyid(r.id.welcome);                                             welcome.settext("hello "                                                     + user.getname() + "!");*/                                             finish();                                              log.d("user name",""+user.getname()+"     "+user.getfirstname()+"    "+user.getlastname()+"    "+user.getproperty("email")+user.getbirthday()+user.getlocation().getproperty("name"));                                         }                                     }                                 });                     }                 }             });           }     }) ; 

please correct me wrong

i've seen problem happen because of wrong hash key generation. rather doing keytool stuff try pasting code in 1 of oncreate generate right key , paste app section on facebook.

packageinfo info; try {     info = getpackagemanager().getpackageinfo("com.you.name", packagemanager.get_signatures);     (signature signature : info.signatures) {         messagedigest md;         md = messagedigest.getinstance("sha");         md.update(signature.tobytearray());         string = new string(base64.encode(md.digest(), 0));         //string = new string(base64.encodebytes(md.digest()));         log.e("hash key", something);     } } catch (namenotfoundexception e1) {     log.e("name not found", e1.tostring()); } catch (nosuchalgorithmexception e) {     log.e("no such algorithm", e.tostring()); } catch (exception e) {     log.e("exception", e.tostring()); } 

this generate key in logcat. check this more ways generate hash key correctly
