今天在測試模塊功能時，出現WindowLeaked的問題，Log如下：

問題是翻遍代碼，也沒有發現重啟該activity的地方，相當詭異。
于是baidu google之后，終于有網友的慷慨提示說是不是橫豎屏幕切換/軟件盤/sim卡等原因引起configChanges，從而引起Activity生命周期重走導致的？
于是我在log中搜索change發現如下可疑log：

從如下關鍵log可以看出onConfigureChanged確實走了，由此可以確定確實是ConfigureChanged導致生命周期重走，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......而事實是中間沒有進行任何與語言時區修改有關的操作，又陷入了抓狂中……一頓糾結之后，終于發現，在該activity的onCreate中判斷某服務沒有啟動時，會跳轉到一個splash頁面啟動服務，而該splash頁面是豎屏的！在menifest中修改該splash頁面的orentation與后面的一致，ok問題解決。
<activity android:name="com.screens.SplashActivity"           android:screenOrientation="landscape" />當然也可以重寫Activity的onConfigurationChanged方法進行處理，這需要看具體情況。希望能給遇到類似問題的朋友一點靈感·～感謝網友的慷慨分享：http://blog.csdn.net/u013951778/article/details/52612083
