In my case, I had a comment /* launch_screen.xml */ at the beginning of my launch_screen.xml file. After removing /* launch_screen.xml */ comment from my code I was able to solve this issue

Perform Build Clean and Rebuild Project did not work for me.

I had to manually delete .idea/caches, then rebuild project.

Old question but googling the error got me here.

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.

I am having the same problem What I did is,

You need to clear the cache data

Go to Build(Menu)--> Clean Project

Then

Go to Build(Menu)--> Rebuild Project

Then Run Your project

This may also help in refreshing data of android preview

Try the following steps

Go to the Build Menu.
Select the option Clean Project.
Once again, go to the Build Menu.
Select the option Rebuild Project.

It worked for me.

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.

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

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.

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

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

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.
