的onDestroy（）并不总是被调用。如果调用，执行的code的一部分。 和大多数在LogCat中的时候，我只看到消息上摧毁GPS状态，被称为第一次。这是为什么呢？

 保护无效的onDestroy（）{
    super.onDestroy（）;
    Log.d（关于灭称为，GPS状态上摧毁被称为第一次）;

    editor.putBoolean（gpsOn，假）;
    Log.d（关于灭称为，GPS状态上摧毁所谓的第二）;
    editor.commit（）;

    Log.d（关于灭称为，GPS状态上摧毁所谓第三）;
    stopRouteTracking（）;
    Log.d（关于灭称为，GPS状态上摧毁所谓的第四次）;





}
 

解决方案

看看这个：

活动的OnDestroy从来不叫？

和这样的：

的http://developer.android.com/reference/android/app/Activity.html#onDestroy%28%29

基本上，从未有保证，的onDestroy（）将被调用，并在某些情况下，如你的应用程序将被直接打死，反正绕过方法调用。

onDestroy() is not always called. If called, only part of the code is executed. And most of the time in LogCat I only see the message "gps state on destroy called first". Why is that?

protected void onDestroy(){
    super.onDestroy();
    Log.d("on destroy called", "gps state on destroy called first");

    editor.putBoolean("gpsOn", false);
    Log.d("on destroy called", "gps state on destroy called second");
    editor.commit();

    Log.d("on destroy called", "gps state on destroy called third");
    stopRouteTracking();
    Log.d("on destroy called", "gps state on destroy called  fourth");      





}

Take a look at this:

Activity OnDestroy never called?

And this:

http://developer.android.com/reference/android/app/Activity.html#onDestroy%28%29

Basically, there's never a guarantee that onDestroy() will be called, and in some cases processes such as your app will be killed directly, bypassing the method call anyway.
