今天在测试模块功能时，出现WindowLeaked的问题，Log如下：

问题是翻遍代码，也没有发现重启该activity的地方，相当诡异。
于是baidu google之后，终于有网友的慷慨提示说是不是横竖屏幕切换/软件盘/sim卡等原因引起configChanges，从而引起Activity生命周期重走导致的？
于是我在log中搜索change发现如下可疑log：

从如下关键log可以看出onConfigureChanged确实走了，由此可以确定确实是ConfigureChanged导致生命周期重走，而引起重走的原因是locale修改：
I/HwSystemManager(3625): HsmPackageManager:onConfigureChanged: zh_CNW/ws000(13240): Application#onConfigurationChanged() is invoked!!!...I/HwLauncher(26780): Model  onReceive intent=Intent { act=android.intent.action.CONFIGURATION_CHANGED flg=0x70000010 }I/PanelView(3267): Configuration orientation changed......而事实是中间没有进行任何与语言时区修改有关的操作，又陷入了抓狂中……一顿纠结之后，终于发现，在该activity的onCreate中判断某服务没有启动时，会跳转到一个splash页面启动服务，而该splash页面是竖屏的！在menifest中修改该splash页面的orentation与后面的一致，ok问题解决。
<activity android:name="com.screens.SplashActivity"           android:screenOrientation="landscape" />当然也可以重写Activity的onConfigurationChanged方法进行处理，这需要看具体情况。希望能给遇到类似问题的朋友一点灵感·～感谢网友的慷慨分享：http://blog.csdn.net/u013951778/article/details/52612083
