无法解析符号 R，Android Studio 中的 gen 文件夹在哪里? [英] Cannot resolve Symbol R, where is gen folder in Android Studio?

问题描述

我在 Android Studio 中创建了一个虚拟的 Android 项目，我可以让它运行，但编辑器本身无法找到 R 类.事实上，我找不到 gen 文件夹.我想也许应该将该文件夹添加为源文件夹或类依赖项，但我找不到它.

I have created a dummy Android project from within Android studio, and I can make it run, but the Editor itself fails to find the R class. In fact I can't find the gen folder. I thought that maybe that folder should be added as a source folder or a classes dependency, but I just can't find it.

有人可以帮忙吗?

推荐答案

@joe_deniable 给了我在 build 文件夹中仔细查看的想法，我发现了一个被 intellij 排除 的文件夹，在那里我的 R 很高兴地吃着冰淇淋.这是在这里:

@joe_deniable gave me the idea to look closer in the build folder, and I found a folder that had been excluded by intellij, where my R was happily having an ice cream. This was here:

构建/源代码/辅助/调试

build/source/aidl/debug

我必须从排除列表中删除此文件夹并将其添加到源中，然后终于可以在这个新的 IDE 中开始编码了.

I had to remove this folder from the exclusion list and add it to the sources, and could finally start coding in this new IDE.

谢谢
