本文介绍了一种解决Launcher在添加视频插件后因语言设置变化导致应用异常终止的问题。通过调整onRestoreInstanceState方法的异常处理策略，确保了不同类型的视图使用唯一ID，避免了错误状态类异常。

在launcher上添加播放视频的插件后，改变当前的语言设置，返回到主界面后会出现异常终止的bug，以下是Log：

Error Log:java.lang.IllegalArgumentException: Wrong state class, expecting View State but received class android.appwidget.AppWidgetHostView$ParcelableSparseArray instead. This usually happens when two views of different type have the same id in the same hierarchy. This view's id is id/0xff0000. Make sure other views do not use the same id.

以下是launcher对应的代码：

if (mSavedInstanceState != null) { super.onRestoreInstanceState(mSavedInstanceState); mSavedInstanceState = null; }我不知道咋么进行修改，看了下ADWLauncher对应的代码，以下是它的处理方式及说明：

//ADW: sometimes on rotating the phone, some widgets fail to restore its states.... so... damn. try{ super.onRestoreInstanceState(mSavedInstanceState); }catch(Exception e){} mSavedInstanceState = null;我也这样进行修改后就没有出现过问题了～～
