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

问题描述

我已经在Android Studio中创建了一个虚拟Android项目，可以运行它，但是Editor本身找不到R类.实际上我找不到gen文件夹.我认为也许应该将该文件夹作为源文件夹或类依赖项添加，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.

任何人都可以帮忙吗?

推荐答案

@joe_deniable让我想到了在build文件夹中仔细查看的方法，然后我发现了一个被intellij 排除的文件夹，我的R高兴地在那里吃冰淇淋.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:

build/source/aidl/debug

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，最后才能在此新IDE中开始编码.

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
