I am working on Android studio for quite a while and few days back I encountered a weird problem. 我在Android Studio上工作了一段时间，几天前我遇到了一个奇怪的问题。 While working on an app implementing a database, I clicked on run app to check, then the build stopped immediately and gave me an error gradle build finished with 3 errors . 在开发实现数据库的应用程序时，我单击了运行应用程序以进行检查，然后构建立即停止，并给了我一个错误gradle构建，其中包含3个错误 。

Another time, while the gradle was building the project, R.java class gets opened up in a new tab on its own and one of the variable's name gets an error. 还有一次，在gradle构建项目时， R.java类自己在新选项卡中打开，并且变量名之一出现错误。 Even though the screen showed that I should not tamper the R.java file contents. 即使屏幕显示我不应该篡改R.java文件的内容。

I tried renaming that mistyped variable to its correct name again (variable's correct name is et_linked_username and it showed et-linked-username in R.java class) and rebuilt the project but NOTHING WORKS, ITS ALL THE SAME. 我尝试再次将错误输入的变量重命名为其正确的名称（变量的正确名称为et_linked_username并且在R.java类中显示了et-linked-username ），并重新构建了项目，但没有任何效果，全部相同。

I believe something is wrong with the project itself, because its working absolutely fine on other projects. 我相信该项目本身存在问题，因为它在其他项目上的运行情况绝对良好。

You should never change the R.java file, its a system generated file. 您永远不要更改R.java文件，它是系统生成的文件。 Try to clean your project and rebuild it. 尝试清理您的项目并重建它。 You need to go to tools and access the options there. 您需要转到工具并在其中访问选项。
