Old version of package androidx.versionedparcelable

Bugs and Other Issues
1

On devices with newer Android versions I get the error that method ParcelUtils.putVersionedParcelable is not found. Looking at folder ...\appinventor-sources\appinventor\lib\android\support I find the files versionedparcelable-1.0.0.aar and versionedparcelable-1.0.0.aar. Version 1.0.0 is very old (2018) and indeed does not support method ParcelUtils.putVersionedParcelable. The current version of that package is 1.2.1. which has this function impemented.

I ask you to use a newer version of package androidx.versionedparcelable.

I already reported this on github some time ago. I got a response that it is not that simple and obvious. Androidx libraries have a specific minSdk. The latest ones have minSdk = 21. In turn, app inventor supports devices up to sdk 7. Probably this year the support will change and devices up to sdk14 will be supported. Then they will be able to change the library versions a bit. The oldest versionedparcelable library that has the putPersionedParcelable method is 1.1.1 with minSdk=14.
