If you excluded certain Libraries, issues are present.

[RoyTheReal]

Describe the bug If you exclude Sketchwares default Activity Library or Core Library you get errors even if you replace them with newer versions.

To Reproduce Steps to reproduce the behavior:

1. In the newest Sketchware Pro snapshot, Exclude the Default Activity 1.3.0 and/or CoreLibrary
2. Replace with newer version (ex. Activity 1.9.0) in local libraries
3. Try to build project
4. Notice that you get compile Errors OR the app crashes once built ...

Expected behavior You should be able to build the project with the new Activity version and Core version and if compiled, app shouldn't crash. Everything should work fine because new versions are present.

This happens when replacing other libraries as well.

Yeah I tried to do the same a lot of times, but all in vain. I had newer versions of the "AppCompat" and "AppCompat Resources" library and tried to exclude them with the newer versions enabled, but the app always freezed on startup.

I think you should add/update androidx.lifecycle dependency too.

Libraries have specific dependencies and they have specific versions too. You can try downloading e.g. AndroidX activity 1.3.0 with the Local library Downloader and it'll download the correct dependencies as well, e.g. the correct AndroidX lifecycle version.
