Build warning mapping new ns to old ns – Android

The “build warning mapping new ns to old ns android” error usually occurs when there is a conflict between the namespace of an Android project and the namespace of a library or dependency that is being used in the project. This can happen when the namespace of the library or dependency has changed, but the project is still using the old namespace.

To fix this error, you can try the following steps:

  1. Check the library or dependency that is causing the conflict and see if there is a newer version available. If so, update the library or dependency to the latest version and see if that resolves the error.
  2. If the library or dependency is not being actively maintained, you may need to remove it from your project and find an alternative solution.
  3. Make sure that you are using the correct namespace in your project. This can usually be found in the documentation or source code of the library or dependency.
  4. If you are using multiple libraries or dependencies, make sure that they are all compatible with each other. Conflicts can occur when different libraries or dependencies use the same namespace or when they are not compatible with the version of Android that you are using.
  5. Clean and rebuild your project to ensure that all of the dependencies and libraries are properly included and that there are no conflicts.

If these steps don’t help, you may need to consult the documentation or seek help from the community for the specific library or dependency that is causing the conflict.
