Android - 如何确保我的服务重新启动？ [英] Android - how to make sure my Service is restarted?

问题描述

我有一个带有后台运行服务的Android应用程序。

当服务崩溃或被Android杀死时，我可以看到Android尝试重新启动它。 / p>

但是，服务从未真正重新启动，我可以看到Android计划重新启动，但新的确实发生了。

代码如下：

---

  @Override 
 public void onCreate ）{
 String ns = Context.NOTIFICATION_SERVICE; 
 mNotificationManager =（NotificationManager）getSystemService（ns）; 
 mTelephonyManager =（TelephonyManager）getSystemService（Context.TELEPHONY_SERVICE）; 
 audio_service =（AudioManager）getSystemService（Context.AUDIO_SERVICE）; 
 
 
} 
 
 //这是旧的onStart方法，将在2.0之前的
 //平台上调用。在2.0或更高版本上，我们重写onStartCommand（），所以这个
 //方法不会被调用。 
 @Override 
 public void onStart（Intent intent，int startId）{
 handleCommand（intent）; 
} 
 
 @Override 
 public int onStartCommand（Intent intent，int flags，int startId）{
 handleCommand（intent）; 
 //我们希望此服务继续运行，直到显式
 //停止，因此返回sticky。 
 return START_STICKY; 
} 
 
 void handleCommand（Intent intent）{
 
 running = true; 
 mTelephonyManager.listen（new IncomingListener（），PhoneStateListener.LISTEN_CALL_STATE）; 
 
}

解决方案

您是否尝试过使用 startForeground ）？

I have an Android application with a background running Service.

When the Service crashes or gets killed by Android I can see that Android tries to restart it again.

However the Service never actually restarts, I can see Android scheduling the restart but it new actually happens.

My code is as follows:

---

@Override
public void onCreate() {
    String ns = Context.NOTIFICATION_SERVICE;
    mNotificationManager = (NotificationManager) getSystemService(ns);
    mTelephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
    audio_service = (AudioManager) getSystemService(Context.AUDIO_SERVICE);


}

// This is the old onStart method that will be called on the pre-2.0
// platform.  On 2.0 or later we override onStartCommand() so this
// method will not be called.
@Override
public void onStart(Intent intent, int startId) {
    handleCommand(intent);
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    handleCommand(intent);
    // We want this service to continue running until it is explicitly
    // stopped, so return sticky.
    return START_STICKY;
}

 void handleCommand(Intent intent) {

        running = true;
        mTelephonyManager.listen(new IncomingListener(), PhoneStateListener.LISTEN_CALL_STATE);

    }

Is there something missing in my code to allow the Service be restarted?

解决方案

Have you tried using startForeground()?
