Android: AppState.memoryWarning never called for Android

[bradstiff]

Description

The memoryWarning event of AppState appears to be iOS-only, as it is never called on Android.

Android has an onTrimMemory callback that seems to be analogous to the iOS didReceiveMemoryWarning. Could that be used?

I have an app in the field (We Ski and Snowboard Tracker) where memoryWarning events are logged to firebase. 100% of those events are iOS.

In v0.71.4, if I invoke a send-trim-memory event via adb, I get a memoryWarning event. Was this added recently to Android?

Edit: I only get a memoryWarning on debug builds. Why is this not supported on release builds?
