android - My Intent.Extras is always null when I click a notification. How can I get the Intent data? -

i'm unable intent's extras data when view notification. following how build notification, , intent data pass it. there wrong it? i've seen other examples similar appeared work.

    protected override void onmessage(context context, intent intent)     {             // irrelevant stuff removed              string title = "notification";             string message = "the notification message";              bundle valuesforactivity = new bundle();             valuesforactivity.putint("panelid", (int)panelid);              intent pendingintent = new intent(context, typeof (tabcontainer));             pendingintent.putextras(valuesforactivity);             pendingintent.setflags(activityflags.singletop);             pendingintent.putextra("panelid", (int)panelid);              //neither pendingintentflags.cancelcurrent or pendingintentflags.updatecurrent works             pendingintent resultpendingintent = pendingintent.getactivity(context, 0, pendingintent, pendingintentflags.cancelcurrent);             //pendingintent resultpendingintent = pendingintent.getactivity(context, 0, pendingintent, pendingintentflags.updatecurrent);              var builder = new notificationcompat.builder(context);             builder.setcontenttitle(title);             builder.setautocancel(true);             builder.setsmallicon(resource.drawable.icon24);                 builder.setlargeicon(bitmapfactory.decodestream(context.resources.openrawresource(resource.drawable.icon96)));                 builder.setcontenttext(message);             builder.setcontentintent(resultpendingintent);             builder.setticker(title);             builder.setvibrate(new long[] { 100, 200, 300 });              var notificationmanager = getsystemservice(context.notificationservice) notificationmanager;             notificationmanager.notify(1, builder.build());     } 

then in tabcontainer activity, never have data need:

public class tabcontainer : tabactivity {     protected override void onresume()     {         base.onresume();          int panelid = intent.getintextra("panelid", 0); // 0          var extras = intent.extras; // null      } } 

this worked:

public class tabcontainer : tabactivity {     protected override void onnewintent(intent intent)     {         base.onnewintent(intent);          try         {             var panelid = intent.getintextra("panelid", 0);              // things need panelid.         }         catch (exception ex)         {             dealwitherror(ex);         }     } }
