Android Question B4A 12.2 problem with old projects, maybe it only concerns the camera

[vmag]

In version B4A 12.2, some old projects from among the examples stopped working, for example this one ...
Compilation and installation occur without errors,
but after launching the application does not work.
Tested on an emulator with android 7 and on a smartphone with android 9

Instead of making 15 posts saying "I have a problem", the correct approach is:

Step 1:
Post the error message:

2. Now it becomes trivial. Search for: "You must have the following declaration within"
You will immediately find that you need to add:

CreateResourceFromFile(Macro, FirebaseAnalytics.GooglePlayBase)

3. Everything works.

Thank you very much!
After adding the magic string to the manifest

CreateResourceFromFile(Macro, FirebaseAnalytics.GooglePlayBase)

the problematic project now works even on android 5 with the new android library-33+ sdk.
B4X is great!
