Android Question [SOLVED] ACTIVITY_RECOGNITION permission Android 11

[roncoa]

After updating my phone to Android 11, my app using the permissions of ACTIVITY_RECOGNITION, no longer works.

Now the app crashes on startup.
I get this error in debug mode: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.Object java.lang.ref.WeakReference.get()' on a null object reference

Thank you to those who will help me.

You cannot call rp.CheckAndRequest from a service.

Solved, thank you.
I haven't had this problem in the past.
