推荐答案

这是一个已知的问题.也许你应该试试这个:

It's a known issue. Maybe you should try this:

这里有同样的问题，为了避免每次都重建，我要去我的模块项目设置 -> 依赖项和我的库项目之一 -> 应用 -> 好的 -> 重新生成 R.java.

Same issue here, to avoid rebuild EACH TIME, i'm going to my module project settings -> Dependencies and up or down one of my library item -> Apply -> Ok -> Make regenerating R.java.

您也可以尝试在编译器设置中取消选中使用外部构建":

You could also try unchecking "Use external build" in compiler settings:

文件 -> 设置 (Ctrl+Alt+S) -> 编译器 -> 取消选中使用外部构建"

File -> Settings (Ctrl+Alt+S) -> Compiler -> Uncheck "Use external build"
