问题描述
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:
和这样的:
的
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");
}
解决方案
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.
