I was having a similar issue. However, the comments did not assist me in the solution to this issue. This answer from this question actually solved my problem.

Summary:

Go to "File > Project Structure > Modules", click "add" and then click "android" and "apply/ok". That should solve anyone having a similar problem but the comments for this question are not helping you.

Answer 3

Some special characters not allowed here. Directly to assign text then with warning

android:text="value"

@string file from get then avoid warning

android:text="@string/hello"

res/values/strings.xml

 <?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="hello">Hello!</string>
</resources>

Answer 4

I got the same error for a long time and none of the answers I found online really helped me, or probably I wasn't looking the right way. At the end what I found out was the way I named the directory. So, I was trying to make the landscape layout for my app and named it layout_land. That kept showing me the URI is not registered error. I just had to change the directory name to layout-land.

Summary: No underscores in directory names!

My issue was creating new resource directory for some animation work. The files were .xml and I chose file type as "xml". I got this problem. Changing the file type to "values" and the problem went away. No idea why, could someone explain this to me? I'm using Android Studio on an iMac.

GO to settings >Language&Framework >Schemas&DTD here add Uri used in your code.
