Question

我试图推翻一项服务的职能。我有一个服务,我正在利用另一个接见机。然而,产出不是预期的,但我怀疑,压倒String(String)失败! 谁能帮助? 增编

///////////////toString Function in the service !///////////////

public String toString() {
   return "Hello World";
}

//////////how I am calling the overridden function !////////////////////

ActivityManager am = (ActivityManager)this.getSystemService(ACTIVITY_SERVICE);

List<ActivityManager.RunningServiceInfo> rs = am.getRunningServices(50);

for (int i=0; i<rs.size(); i++) {
    ActivityManager.RunningServiceInfo rsi = rs.get(i);
    Log.i("Hello",rsi.getClass().toString());
    Log.i("Service", "Process " + rsi.process + " with component " + 
            rsi.service.getClassName());
}

Answer 1

You expect to have rsi.getClass().toString() return "Hello World" right? It doesn t work as expected above, because you call another toString method in another object. You call this function: http://developer.android.com/reference/java/lang/Class.html#toString()

Problem here is, that RunningServiceInfo only tells you about what Service is running. It doesn t actually give you the object of your service.

现在,你们如何能够纠正? 取决于你们想要做什么。

But the nicest way to access your service out of another application is to bind to it. If your Service is in the same app, you can follow this tutorial: http://www.androidcompetencycenter.com/2009/01/basics-of-android-part-iii-android-services/
