all class

public class splashscreen extends activity {     static context context;     connectivitymanager connectivitymanager;     networkinfo wifiinfo, mobileinfo;     boolean connected = false;     private static splashscreen instance = new splashscreen();      public static splashscreen getinstance(context ctx) {         context = ctx.getapplicationcontext();         return instance;     }      public boolean isonline() {         try {             connectivitymanager = (connectivitymanager) context                     .getsystemservice(context.connectivity_service);              networkinfo networkinfo = connectivitymanager.getactivenetworkinfo();             connected = networkinfo != null && networkinfo.isavailable() &&                     networkinfo.isconnected();             return connected;           } catch (exception e) {             system.out.println("checkconnectivity exception: " + e.getmessage());             log.v("connectivity", e.tostring());         }         return connected;     }      @override     protected void oncreate(bundle savedinstancestate) {         // todo auto-generated method stub         super.oncreate(savedinstancestate);         setcontentview(r.layout.splash);          thread timerthread = new thread(){             public void run(){                 try{                     sleep(3000);                  }catch(interruptedexception e){                     e.printstacktrace();                 }finally{                      if (splashscreen.getinstance(this).isonline()) {                          intent = new intent(splashscreen.this, mainactivity.class);                         startactivity(i);                      } else {                          //toast t = toast.maketext("test").show();                         //log.v("home", "############################you not online!!!!");                         intent = new intent(splashscreen.this, chatonly.class);                         startactivity(i);                     }                  }             }         };         timerthread.start();     }      @override     protected void onpause() {         // todo auto-generated method stub         super.onpause();         finish();     }    } 

use this,

new handler().postdelayed(new runnable() {              @override             public void run() {                 if (isonline()) {                             intent = new intent(splashscreen.this, mainactivity.class);                         startactivity(i);                      } else {                          //toast t = toast.maketext("test").show();                         //log.v("home", "############################you not online!!!!");                         intent = new intent(splashscreen.this, chatonly.class);                         startactivity(i);                     }             }         }, 3000);
