This app was built for an older version of Android

The following message appears when opening the app for the first time on Android 9+ (Pie):

This app was built for an older version of Android and may not work properly. Try checking for updates, or contact the developer.

According to the Cordova Android Platform Guide, Cordova only supports up to Android 9:

https://cordova.apache.org/docs/en/latest/guide/platforms/android/index.html#requirements-and-support

cordova-android Version	Supported Android API-Levels	Equivalent Android Version
7.X.X	19 - 27	4.4 - 8.1

According to this pull request, Android Pie support was added in cordova-android version 7.1.4: apache/cordova-android#573

That's only part of the issue, though. The other part is that we are using PhoneGap Build to build the app currently, and it looks like that only supports up to 7.1.2: https://build.phonegap.com/current-support

Unless that page is outdated... the official Cordova doc page was also outdated (says it only support up to Android 8.1, but Pie is 9. Might be worth retrying...

I believe this has been alleviated by fact that I've gone back to building the Android app via Cordova CLI.
