What are the steps to reproduce this bug?

1. Open Ankidroid and another application in split screen.

3. Resize the split between the two applications (this can be done manually or automatically when the second application changes).
4. The new card's content is reset.

Thanks for reporting this - probably an activity/fragment lifecycle issue
Anyone looking to triage this: examine Activity methods that deal with the saved instance state Bundle, and same for Fragments involved in this screen

[BrayanDSO]

In the long term, the Note Editor will be migrated into a WebView page, and the content of one isn't recoverable after a activity is recreated, so using android:configurationChanges="screenSize" is acceptable here IMO.

Saving the state would be the ideal fix, but the work would be temporary.

[mikehardy]

good point re: moving to webview etc. agree just ignore config change then to see if it works

[david-allison]

This worked before, I'd like to treat it as a regression and fix it properly

[mikehardy]

we could but we do only have limited attention - perhaps best served exposing note editor from upstream
but it's open source, anyone can work on anything in reality
