在特定時間後啓動服務android

Question

我已在我的項目中提供服務，並且我希望在每2分鐘後開始啓動。我正在使用下面的代碼，但它不能正常工作。

public class ScheduleSync extends BroadcastReceiver{ 

    @Override 
    public void onReceive(Context context, Intent intent) 
    { 
     AlarmManager service = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); 

     Intent i = new Intent(context, StartMyServiceReceiver.class); 
     PendingIntent pending = PendingIntent.getBroadcast(context, 0, i,PendingIntent.FLAG_CANCEL_CURRENT); 
     Calendar cal = Calendar.getInstance(); 
     service.setInexactRepeating(AlarmManager.RTC_WAKEUP,cal.getTimeInMillis(), 60000*2, pending); 

    } 

} 



public class StartMyServiceReceiver extends BroadcastReceiver 
{  
    public void onReceive(Context context, Intent intent) 
    { 
     Toast.makeText(context, "receive broadcast", Toast.LENGTH_LONG).show(); 
     Log.d("StartMyServiceReceiver", "receive broadcast"); 
     Intent service = new Intent(context, myservice.class); 
     context.startService(service); 
    } 
} 

好心幫我解決這個問題。當我看到taskmanager myservice正在後端運行時。

爲什麼要用AlarmManager？

只需使用Thread.sleep(xxxx)：

public class ScheduleSync extends BroadcastReceiver{ 
    private Context context; 
    private void startOtherService(){ 
     Intent i = new Intent(context, StartMyServiceReceiver.class); 
     context.startService(i); 
    } 
    @Override 
    public void onReceive(Context context, Intent intent) 
    { 
     this.context = context; 
     new Thread(new Runnable(){ 
      public void run(){ 
       try{ 
        Thread.sleep(2*60*1000); 
        startOtherService(); 
       }catch(InterruptedException e){ 
        e.printStackTrace(); 
       } 
      } 
     }).start(); 
    } 

}
