Is there a way of gracefully handling this so that if they aren’t up to date? Maybe at least deliver a nice screen that tells them to update?

Is there a recommended way to configure an emulator to simulate these devices?

What is the highest webview android 5 can update to? According to wikipedia, it is no longer supported. https://en.wikipedia.org/wiki/Android_version_history
