android - how i can intent from notification? -

why intent notification null?

intent resultintent = new intent(context, myclass.class);         resultintent.addflags(intent.flag_activity_new_task |                 intent.flag_activity_single_top);         bundle extras=new bundle();         extras.putstring("key","value");         pendingintent resultpendingintent =                 pendingintent.getactivity(                         context,                         0,                         resultintent,                         pendingintent.flag_update_current                 );             notificationcompat.builder n = new notificationcompat.builder(context)                     .setcontenttitle("test")                     .setcontenttext(text)                     .setsound(sound)                     .setcontentintent(resultpendingintent)                     .setautocancel(true)                     .setextras(extras)                     .setsmallicon(android.r.drawable.ic_media_play);             notificationmanager notificationmanager = (notificationmanager) context.getsystemservice((context.getapplicationcontext().notification_service));             notificationmanager.notify(0, n.build());     } 

but in onstart() of myclass when call getintent().getextras() result null, why? how can getextras() notification intent ?

i think u forgot call.

resultintent.putextras(extras); 

before calling it.
