Summary
New Game opens the Constructed lobby again on Android 8 to 13.
Bug report
After updating, tapping New Game on Android does nothing. The other home screen buttons work. The log shows:
Root cause
#12521 builds `FormatChoices.FORMAT_GAME_TYPES` with `Stream.toList()`, which was added in Java 16. Android's runtime only has that method from Android 14 (API 34), and the app's minimum is API 26. On older devices the class fails to load, so `LobbyScreen` can't be built. Desktop and CI run on a full JDK and do not catch it.Fix
Collect the stream with
Collectors.toList(), as other shared code does. No other code that Android runs callsStream.toList().🤖 Generated with Claude Code
