onConfigurationChanged is not called&& 翻转屏幕不执行onConfigurationChanged方法&&onConfigurationChanged不执行

 

我总结出一句话：

如果target sdk>=13,必须使用如下方式声明activity：android:configChanges="orientation|screenSize" 否则不会调用onConfigurationChanged方法！！！

原文：

Caution: Beginning with Android 3.2 (API level 13), the "screen size" also changes when the device switches between portrait and landscape orientation. Thus, if you want to prevent runtime restarts due to orientation change when developing for API level 13 or higher (as declared by the minSdkVersion and targetSdkVersionattributes), you must include the "screenSize" value in addition to the "orientation" value. That is, you must decalare android:configChanges="orientation|screenSize". However, if your application targets API level 12 or lower, then your activity always handles this configuration change itself (this configuration change does not restart your activity, even when running on an Android 3.2 or higher device).
