### Android Studio
```
Android Studio 4.0 Beta 4
Build #AI-193.6911.18.40.6348893, built on March 30, 2020
Runtime version: 1.8.0_242-release-1644-b3-6222593 amd64
VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
Linux 5.4.30-1-MANJARO
GC: ParNew, ConcurrentMarkSweep
Memory: 1246M
Cores: 4

```

### Details of the issue:
When I build an app bundle with the following settings, I do not have the problem with
ClassNotFoundException for OnUnhandledKeyEventListener when running in the emulator or a device.

```
project.ext {
minSdkVersion = 21
compileSdkVersion = 29
buildToolsVersion = '29.0.3'
}
```

However, when running the app bundle, it shows the stacktrace error as an information message in Logcat.

_i.e. Rejecting re-init on previously-failed class java.lang.Class<android.support.v4.view.ViewCompat$OnUnhandledKeyEventListenerWrapper>: java.lang.NoClassDefFoundError: Failed resolution of: Landroid/view/View$OnUnhandledKeyEventListener;_

Please advice what can be the possible cause, and provide a solution if any.

Application get crashed when Recylerview reach at end(last page). Inside GithubRemoteMediator.kt I have set val endOfPaginationReached = page > 2 to allow maximum 2 pages for testing. So, the problem is when I reach at the last page of list, application get crashed as remoteKeys.nextKey is null(as we have set nextKey=null for last page of list).

Do you have a stack trace for the crash you could share?

Offline cache broken How to support caching when application is open without internet connection. currently it is showing retry button. How to show previously loaded data. I have tried to fix this by removing

This might be due to loadStateFlow / listener logic on the PagingDataAdapter which hides / shows UI elements based on load state. You'll want to modify that logic to only listen to remote errors and not the local ones as well.

1. stack for remoteKeys.nextKey gets null

2. I have checked loadStateFlow / listener logic and changed it to listen only remote errors using loadState.mediator.refersh. But still, in offline mode application shows empty list. I have also removed the loadStateFlow / listener but still, it's not working in offline mode. It is not fetching data available in databa.

Re: 1. That check was built into the codelab since it doesn't expect to run out of pages to append, but since you changed the logic you'll also need to update that check here: https://github.com/googlecodelabs/android-paging/blob/step13-19_network_and_database/app/src/main/java/com/example/android/codelabs/paging/data/GithubRemoteMediator.kt#L68

You can simply replace it by returning MediatorResult.Success(endOfPaginationReached = true)

Re: 2. I ended up repro-ing this and fixing it, should be released with alpha02.
