xamarin.android - Android Scheduled Timer - Mono for Android or Java -

i need run method every 5 seconds using mono android. there scheduled timer in android? have tried code, however, fails start:

using system; using system.collections.generic; using system.linq; using system.text; using android.app; using android.content; using android.os; using android.runtime; using android.views; using android.widget; using glass.core.interfaces; using glass.core; using java.util;  namespace glass.ui.an { [application(label = "glass", icon = "@drawable/icon")] public class glassapplication : application {     context context;      public glassapplication (intptr handle, jnihandleownership transfer)         : base(handle, transfer)     {         this.context = basecontext;     }      public override void oncreate ()     {         base.oncreate ();         timer timer = new timer ();         timer.scheduleatfixedrate (new customtimertask(context), new date(datetime.now.year, datetime.now.month,          datetime.now.day, datetime.now.hour, datetime.now.minute), 5000);     } }  public class customtimertask: timertask {     context context;      public customtimertask(context context)     {         this.context = context;     }      public override void run ()     {         glasswebserviceprovider p = new glasswebserviceprovider (context);         p.sendcardreaders ();     } } 

}

why not use system.timers.timer?

var timer = new timer(); //what when time elapses timer.elapsed += (sender, args) => firethemissiles(); //how (5 sec) timer.interval = 5000; //start it! timer.enabled = true;  private void firethemissiles() {     //but i'm le tired... } 

another approach make new task or thread , let sleep 5 seconds every time:

task.factory.startnew(() =>     {         while (true)         {             // stuff             thread.sleep(timespan.fromseconds(5));         }     });  threadpool.queueuserworkitem(thread =>     {         while (true)         {             // stuff             thread.sleep(timespan.fromseconds(5));         }     });
