Hi all,
I am upgrading a simple app to targetSDK 31. With SDK 30 everything works correctly. But with version 31, I get the following error in the Google Dev console pre-launch report:
java.lang.reflect.InvocationTargetException:

Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

I found a thread, but the 11.81 core did not help me: [ SOLVED] Target SDK 31 widget crash

Can anyone help me with a solution?

Thank you!

It is not related to this issue.

Looks like you are using an old version of NB6. Are you using latest version of B4A?

I using the 11.80 (64bit) version with this modules:

Hi, I don't quite understand this thread, why should I request this special permission ?
