### 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

```

### 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.

Seems that this issue will never be fixed as google has marked the multiple duplicates as `wont fix`.

Assigned to ki...@google.com.

https://android-review.googlesource.com/c/platform/frameworks/support/+/1295992 is under review.

Adding the following block in Support4Demos.onCreate:

ViewCompat.addOnUnhandledKeyEventListener(getListView(),
new ViewCompat.OnUnhandledKeyEventListenerCompat() {
@Override
public boolean onUnhandledKeyEvent(View v, KeyEvent event) {
return false;
}
});

produces:

on a Nexus 6 API 23 emulator before the CL, and no such message with the CL

Extract v28+ calls into a separate static class

So that the new View.OnUnhandledKeyEventListener class
doesn't get loaded on older platform versions.
