my code:

private static void generatenotification(context context, string message) {     int icon = r.drawable.ic_stat_gcm;     long when = system.currenttimemillis();     notificationmanager notificationmanager = (notificationmanager)             context.getsystemservice(context.notification_service);     notification notification = new notification(icon, message, when);     string title = context.getstring(r.string.app_name);     intent notificationintent = new intent().setclass(context.getapplicationcontext(), demoactivity.class);     // set intent not start new activity     notificationintent.setflags(intent.flag_activity_multiple_task);                          notificationintent.setflags(intent.flag_activity_new_task);       notificationintent.setflags(intent.flag_activity_clear_top |             intent.flag_activity_single_top);     pendingintent intent =             pendingintent.getactivity(context, 0, notificationintent, 0);     notification.setlatesteventinfo(context, title, message, intent);     notification.flags |= notification.flag_auto_cancel;     notificationmanager.notify(0, notification);     notificationintent.putextra("url", message);     // launch new activity , add additional flags intent     context.getapplicationcontext().startactivity(notificationintent);      /*intent = new intent().setclass(context.getapplicationcontext(), demoactivity.class);       i.setflags(intent.flag_activity_multiple_task);                          i.setflags(intent.flag_activity_new_task);       i.putextra("url", message);     // launch new activity , add additional flags intent     context.getapplicationcontext().startactivity(i);*/ } 

activity demo

 public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     checknotnull(server_url, "http://10.0.2.2:8080/gcm-demo-server/");    // checknotnull(sender_id, "972801588344");     // make sure device has proper dependencies.     gcmregistrar.checkdevice(this);     // make sure manifest set - comment out line     // while developing app, uncomment when it's ready.     gcmregistrar.checkmanifest(this);     setcontentview(r.layout.main);     bundle extras = getintent().getextras();     if (extras != null) {         url = extras.getstring("url");     }     web=(webview) findviewbyid(r.id.webview1);     if(url==null)     {             web.loadurl("http://kqxs.vn/trang_chu");     }else     {         web.loadurl(url);     } } 

i fixed following by

 private static void generatenotification(context context, string message) {     int icon = r.drawable.ic_stat_gcm;     long when = system.currenttimemillis();     notificationmanager notificationmanager = (notificationmanager)             context.getsystemservice(context.notification_service);     notification notification = new notification(icon, message, when);     string title = context.getstring(r.string.app_name);     intent notificationintent = new intent(context, demoactivity.class);     // set intent not start new activity     notificationintent.setflags(intent.flag_activity_clear_top |             intent.flag_activity_single_top);     notificationintent.putextra("url", message);     pendingintent intent =             pendingintent.getactivity(context, 0, notificationintent, 0);     notification.setlatesteventinfo(context, title, message, intent);     notification.flags |= notification.flag_auto_cancel;     notificationmanager.notify(0, notification); } 

but have problem, application load correct url first time, 2nd, after receiving new url server, application loaded url of first time. have tried , tried many times still getting results so...

please see following question:

android:what difference between setflags , addflags intent

intent.setflags : means replacing old flags adding new flags intent

intent.addflags : means appending new flags added intent

so, need use notificationintent.addflags instead of notificationintent.setflags appending intent.flag_activity_new_task flag notificationintent intent as:

....... notificationintent.setflags(intent.flag_activity_multiple_task);                   notificationintent.addflags(intent.flag_activity_new_task);   notificationintent.addflags(intent.flag_activity_clear_top |         intent.flag_activity_single_top); .......
