Android Question error: package android.support.v7.app does not exist

[laguilar]

I know there have been several posts about this issue, and I've tried all the solutions mentioned but I am still getting the error "package android.support.v7.app does not exist".

Things I've done:
- Verified Java 8 installed
- Deleted old "Android" SDK folder.
- Updated Android SDK (downloaded from b4a.com/b4a.html)
- Download the latest AppCompat-4.0 that contains the artifact fixes
- Configured Paths (to use the android-30 jar)
- Ran all the latest updates in the Android SDK manager
- Ran Jetify (as administrator)
- Added Line (in Main): #AdditionalJar: com.android.support:appcompat-v7
- Added Line (in Main): #Extends: android.support.v7.app.AppCompatActivity
- Repeatedly restarted B4A (to potentially reload environment changes as i step through each step)
- Before each build I refreshed libraries and ran the "Clean project".

I've been using b4a for many years, I have a sizable project that I have not been able to compile this project since B4A version 9.90, I've been stuck compiling with B4A 9.00.

Any ideas? Thanks.

P.S.: I can offer remote access is someone would like to remote in and take a look.

First step is to update to B4A 11.0 with an updated SDK.

Sorry, I neglected to mention that above, that was of course step 1. See the build log here:

Do you know where AppCompatDelegate come from?

Download and run this example: https://www.b4x.com/android/forum/threads/appcompat-with-toolbar-minimal-example.79896/#content
Does it work?
