Android Question AppCompat problem

[josejad]

Hi all:

I'm having with the B4XDrawer sample the same issue others have had:
Error occurred on line: 217 (B4XDrawer)

Public Sub getCenterPanel As B4XView
    Return mCenterPanel 'Line 217
End Sub

I've searched the forum and I've found several threads with the same issues, and I've tested with no success the described solutions
- Redownload AppCompact 4, which include the jettified library.
- Re-jettify the libraries
- Delete AppCompat.androidx.aar and jetify again.
- There's no AppCompat library in internal libraries folder.
- Delete jetifier.map from the additional libraries folder and run jetifier again

The funny thing is I'm making a skeleton app reusing the Drawer. I had a couple activities working, and they still works. But yesterday I added another activity, and I get the error just in the new ones.
Main, PartesTrabajo, ChecklistNSN works.
CVEOrange and Test (added later): error.

Attached a small project with the error.

Thanks

These are completely different errors.

You forgot to add:

#Extends: android.support.v7.app.AppCompatActivity

to some of the activities.
