Android Studio代码替换为自动生成的代码

Question

//This class was automatically generated by the
 * gradle plugin from the resource data it found. It
 * should not be modified by hand.//

当我重新打开Android Studio并打开所有文件时，我只获得此代码。没有其他代码显示，当我生成APK它的给予力量停止错误总是

我面临的另一个问题是

  

无法从第1行的Misc.xml加载设置错误，Prolog中不允许内容请更正文件内容
