The error: duplicate value for resource 'attr/fontFamily' with config ''

Question

While building project I'm facing this error Android resource compilation failed

Android resource compilation failed

E:\Study\Android\Clients Projects\Smupp\Smupp 1.2.1\Smupp\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml:5397: error: duplicate value for resource 'attr/fontFamily' with config ''. E:\Study\Android\Clients Projects\Smupp\Smupp 1.2.1\Smupp\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml:5397: error: resource previously defined here.

Tried all previously asked similar questions, but they didn't helped. I'm stuck from 4 days.

May be you are using the same attribute name which is used by android system. Please check the attribute file and replace that attribute. — Mahavir Jain, Mar 20 '19 at 06:37

there is no attrs.xml folder – Mar 20 '19 at 06:37
check `values.xml` file. – shizhen Mar 20 '19 at 06:40
in values folder values.xml also not exists – Mar 20 '19 at 06:48
from file explorer I've checked the path and renamed `fontFamily` to `fontsFamily` but It doesn't solved the problem. after rebuilding the project it is again renamed to `fontFamily`. I think `values.xml` file is read only and regenerated on building/running project. – Mar 20 '19 at 11:51
values.xml is read only file, how you can suggest a change into a read only file. – Gaurav Bansal May 29 '20 at 16:51
