Crash on API 21 and 22 only, WebView and Consent SDK - Resources$NotFoundException

Question

We got this crash from a tester on Galaxy S6, Android 5.0.2. Android System WebView 37 (1726107-arm64) Google Play Services 19.0.56 (020400-263933554) Google Play Store 16.5.30-all [0] [PR] 267441717

How to reproduce (apart from the above device): Android studio, emulator Android SDK built for x86_64 api 21 and 22. Above 22 no crash. On same devices, WebView crashes with a similar message. It does not crash with the test publisher id ("pub-0123456789012345") from Android Developers example

Answer 1

Since many libraries are going to depend on appcompat 1.1.0 in the future, I am going to leave this here https://stackoverflow.com/a/58131421/9125569. It happens on devices with API 21 & 22 with webview version<50.
