Hello @Pablo4h
Thanks for writing this issue.
But when does this exception occur?
What exactly are you doing, and can you reproduce this issue?

Good afternoon when I open the MapActivity

This is confusing.
It is an error that never should happen, if the app is installed correctly.
How did you install pocketmaps?
Playstore or FDroid or self-compiled-apk?
Maybe you can try to clear cache of app, and/or reinstall the app?
Also interesting: What is your android version?
