AGP 7.2 - java.lang.NoClassDefFoundError: Failed resolution of: Lorg/jacoco/agent/rt/internal_3570298/Offline; for instrumentation tests

When running android instrumentation tests with AGP 7.2 (android studio chipmunk) I am seeing the following error:

I have jacoco 0.8.8 setup as well, but when I turn debug.testCoverageEnabled to false, the instrumentation tests pass successfully.
Using jacoco 0.8.7 has the same issue, but both 0.8.7 and 0.8.8 work correctly on AGP 7.1.3 (bumblebee).

Unity 2019 - Android - NoClassDefFoundError with custom library and Google Play Service dependencies

I'm working on an App for Android which uses a custom library. This library needs the
implementation 'com.google.android.gms:play-services-ads:17.1.2'
I generate a plugin for unity with Android Studio and build the App. Everything works fine until I start using functions of the custom library. The app crashes with the following error message. What do I have to do to fix this NoClassDefFoundError for the Google Play Service stuff. I'm really stuck.

How to solve a problem which causes app to crash when new dependency is added to gradle?

I am trying to integrate paynow api to my application, I have not done much, so far I have just added this dependance to gradle: implementation 'zw.co.paynow:java-sdk:1.1.1'
Supprisingly the app crashes, if I remove it the app does not crash, so adding it is crashing my app. So my question is, what could be missing that causes this crash?

First clean the project, then invalidate android studio from File -> Invalidate Caches / Restart.. -> Invalidate and Restart.

RxJava 3.0.0 crashes a default Empty Activity project?

I create a new project in Android Studio 3.6 with default Empty Activity.
By just adding this to my gradle, sync and compile,
implementation "io.reactivex.rxjava3:rxjava:3.0.0"
The example app fail to even start, and crash as below

Is this expected (i.e. I miss something), or is it a bug?
Note, adding implementation "io.reactivex.rxjava2:rxjava:2.2.18" compiles fine.

You need to use Android Studio 4.0 or newer (and more importantly, AGP 4.0 or newer) to use RxJava3 in Android projects, because that is what adds the new desugaring capabilities that RxJava3 relies on.

FATAL EXCEPTION: java.lang.ClassNotFoundException: Didn't find class "MainAcitivity" on path: DexPathList

I have searched extensively to find a solution for this issue and tried what I see has been suggested in the past.
Things I tried:
Deleted *.iml files locally
Deleted .idea files locally
Removed the project
Closed Android Studio and re-imported
Invalidated cached
Cleaned and re-builded.
I'm assuming what caused the problem is moving MainActivity to a newly created package. Any suggestions would be greatly appreciated.
