Android Activity onDestroy() 并不总是被调用，如果被调用，只会执行部分代码

Question

onDestroy() 并不总是被调用。如果调用，则只执行部分代码。在LogCat 中，大多数时候我只看到消息“gps state on destroy called first”。这是为什么呢？

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");
}

看看这个:

Activity OnDestroy never called?

还有这个:

基本上，永远无法保证会调用 onDestroy()，并且在某些情况下，诸如您的应用之类的进程将被直接杀死，无论如何都会绕过方法调用。
