Android Question [Solved] AndroidX SDK / Beta 9.30#3 / issue "package ....widget.RecyclerView does not exist"

After switching to the B4A IDE beta 9.30 including changing the SDK to AndoidX the following error message appears when compiling:

The author of the Recyclerview lib is not reachable looking into this at the moment,
so how can I restore the "before SDK"?

I got the same error with this library:

@alimanam3386 is not reachable?

android-support-v4.jar is a very old version. You should delete it.

Can you upload a small project that demonstrates this error?

 

[fredo]

Can you upload a small project...

The libs involved:

They are from @alimanam3386 's "Amir_RecyclerView fullpackage":

[Erel]

Why aren't you using xCustomListView?

Can you send me Amir_RVExpandable library?

 

[Erel]

It compiles fine here after I jetified the library. I'm running an unreleased version that includes a fix for the inner classes conversion. I will release it.

 

[Erel]

Test it with beta #4.

 

[fredo]

Test it with beta #4.

This solved the issue.
Thank you for your quick response!
