<找不到符号R>重命名程序包名称后发生错误 [英] "Cannot find symbol R" error after renaming package name

问题描述

重命名我的项目包名称(使用Refactor)后，出现此错误:

After renaming my project package name (with Refactor), I got this error:

Error:(7, 44) error: cannot find symbol class R

我所有的 R 用法均无效.我尝试手动修复它，但对我不起作用.无效的追逐/重新启动也无济于事.

All of my R usages are invalid. I tried to fix it manually but it doesn't work for me. Invalidate chases/Restart doesn't help me, either.

推荐答案

尝试以下操作:

尝试删除您的R.java文件，Android Studio会重新生成它.

Try deleting your R.java file , android studio will regenerate it.

清洁项目

重建项目

然后检查:

检查AndroidManifest.xml，顶层元素上有一个package属性

Check the AndroidManifest.xml, there's a package attribute on the top-level element

(这取决于您如何重命名程序包名称)

(Well it depends on how you renamed your package name)
