Android showStatusIcon on inactive InputConnection异常
在开发的时候突然发现在输入文本框中点击输入法的删除按钮，发现app莫名其妙退出 了。log信息如下：
01-31 16:57:59.524: W/IInputConnectionWrapper(1259): clearMetaKeyStates on inactive InputConnection 01-31 16:57:59.624: W/IInputConnectionWrapper(1259): clearMetaKeyStates on inactive InputConnection 01-31 16:57:59.624: W/IInputConnectionWrapper(1259): beginBatchEdit on inactive InputConnection 01-31 16:57:59.624: W/IInputConnectionWrapper(1259): getTextBeforeCursor on inactive InputConnection 01-31 16:57:59.624: W/IInputConnectionWrapper(1259): endBatchEdit on inactive InputConnection 01-31 16:57:59.624: W/IInputConnectionWrapper(1259): sendKeyEvent on inactive InputConnection 01-31 16:57:59.624: W/IInputConnectionWrapper(1259): sendKeyEvent on inactive InputConnection 01-31 16:57:59.624: W/IInputConnectionWrapper(1259): clearMetaKeyStates on inactive InputConnection 01-31 16:57:59.684: W/IInputConnectionWrapper(1259): showStatusIcon on inactive InputConnection
后来各种查找，发现原来自己在Activity中重写了onKeyDown方法直接退出了Activity。
所以出现了这种Warn的时候请看看自己代码是否重写了onKeyDown或onKeyUp方法，检查下是否有逻辑上的错误。
