I had an old project, but I wanted to rename it, so I made a duplicate of the old project then renamed the new project's gradle applicationId and created a new signing file for it. But now why can't the new project and the old project be installed on the same device together?

Error:

The reason is that you are using the same provider name/id in two different apps. See this stack overflow post

Basically make sure your provider ids are based on the app id.

Check your package name in build.gradle and in your manifest.. and check if you are using something like facebook or anything that is connected to your old project or package name.
