in "res" directory I create new "database" directory

在“res”目录中我创建了新的“数据库”目录

That is not supported. You cannot invent new resource directories.

这是不支持的。你不能发明新的资源目录。

Please put the files in res/raw/(and use via getResources().openRawResource()) or assets/(and use via getAssets().open()).

请将文件放入res/raw/（并使用 via getResources().openRawResource()）或assets/（并使用 via getAssets().open()）。

In my case, I had accidentally entered a random character right before the beginning of my strings.xml file.

就我而言，我不小心在strings.xml 文件开头之前输入了一个随机字符。

I removed the "f" character before the xml declaration and all was well again.

我在 xml 声明之前删除了“f”字符，一切又好了。

Old question but googling the error got me here.

老问题，但谷歌搜索错误让我在这里。

This was fixed for me by deleting the (empty) "navigation" folder from res, it was left over when checking out a different branch from a repository, appears it can't be empty or it will cause this error.

这是通过从 res 中删除（空的）“导航”文件夹为我解决的，它在从存储库检出不同的分支时遗留下来，看起来它不能为空，否则会导致此错误。

I faced the same error when I created assets folder inside app/src/main/res/

当我在 app/src/main/res/ 中创建资产文件夹时，我遇到了同样的错误

We shouldn't create folders anywhere at our will. To create new folders, make sure that you go to
File -> Folder and consequently ,choose one of the folders among the options displayed. This way the IDE creates the folder at appropriate locations and thus accessing them doesn't raise any errors.

我们不应该随意在任何地方创建文件夹。要创建新文件夹，请确保转到
文件 -> 文件夹，然后在显示的选项中选择文件夹之一。这样，IDE 会在适当的位置创建文件夹，因此访问它们不会引发任何错误。

You can only have predefined set of folder inside res folder. so you are creating database folder inside res folder which is invalid. Either put database files inside assets folder or raw folder.

您只能在 res 文件夹中拥有一组预定义的文件夹。所以你在 res 文件夹中创建了无效的数据库文件夹。将数据库文件放在 assets 文件夹或 raw 文件夹中。

I removed all of the compile statements. Then, I deleted the jar files from libs (and selected 'safe delete'). Once that was done, I dragged the jar file back into libs. Once there, I right clicked on libs selected to add it as a library. Now the gradle builds fine and everything works.

我删除了所有的编译语句。然后，我从库中删除了 jar 文件（并选择了“安全删除”）。完成后，我将 jar 文件拖回库中。在那里，我右键单击所选的库以将其添加为库。现在 gradle 构建良好，一切正常。
