我工作的家长控制/成人内容过滤应用程序。这个程序连续监视对孩子的手机的通话和短信息，并记录所有的活动到服务器。对于这个我开始一个服务（MyService.java） 对BOOT_COMPLETED和服务的onCreate方法我注册一个contentobserver为callLog和短信URI（参见code段以下）。

现在的问题是，因为我要监控每个传出，呼叫进入S和短信我希望服务是时间可持续运行（而不会被停止/杀死）。此外，这种服务被只用于注册内容观察员和没有做任何其他处理（其OnstartCommand方法是假），所以之后的某个Android操作系统杀死服务。 我如何确保服务运行时间可持续，并保持contentobserver对象还活着吗？

谢谢 Srao

解决方案

您可以设置为在前台运行的服务。这会给你的服务被杀害的操作系统低得多的机会。

I am working on parental control/adult content filtering application. This app continuously monitors the calls and smses on a child's mobile and logs all the activity onto a server. For this I am starting a service (MyService.java) on BOOT_COMPLETED and in the onCreate method of the service I register a contentobserver for the callLog and sms uri ( refer to the code snippet below ) .

Now the issue is, Since I want to monitor every outgoing, incoming call s and sms I want the service to be continuosly running ( without being stopped/killed) . Moreover this Service is being just used for registering content observers and not doing any other processing(its OnstartCommand method is dummy ) , so android OS kills the service after sometime. How do I ensure that the service runs continuosly and keeps the contentobserver object alive ?

Thanks Srao

   
public class MyService extends Service {

    private CallLogObserver clLogObs = null;
    public void onCreate() {        
        super.onCreate();       
         try{                           
             clLogObs = new CallLogObserver(this);
             this.getContentResolver().registerContentObserver(android.provider.CallLog.Calls.CONTENT_URI, true, clLogObs);              
         }catch(Exception ex)
         {
             Log.e("CallLogData", ex.toString());
         }
        }

    @Override
    public IBinder onBind(Intent arg0) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public void onDestroy() {   
    if( clLogObs !=null  )
    {
        this.getContentResolver().unregisterContentObserver(clLogObs);
    }
     super.onDestroy();

    }



    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {  
        super.onStartCommand(intent, flags, startId);           

        return Service.START_STICKY;

    }

    @Override
    public boolean onUnbind(Intent intent) {

     return super.onUnbind(intent);
    }

you can set the service to run in the foreground . this will give your service a much lower chance of being killed by the OS .
