Boot Android emulator and debug home screen refresh bug
Session from pi-coding-sessions on Hugging Face by championswimmer · MIT · condensed by Coders Talk
Start a Pixel 9 emulator, install and run the TwoFac Android app on it, then fix a bug where the home screen doesn't refresh with newly imported accounts.
- +0Prompt · +0Start the Pixel 9 emulator and run the Android app on it
- +1mIntervention · +1mThe emulator boot script hung and was aborted; developer confirmed the emulator had actually booted and told the agent to continueWhy: the boot command got stuck so I just checked myself and told it to move on instead of waiting
- +1mAgent did · +1mInstalled the debug APK, hit repeated storage-full errors, cleared caches, eventually wiped emulator data and reinstalled, then launched the app successfully in Resumed state
- +5mPrompt · +5mFix bug: after importing accounts, the accounts screen shows them but the home screen isn't refreshed with the new accounts
- +5mAgent did · +5mTraced the data flow through AccountsViewModel, HomeScreen, SettingsScreen, BackupService, TwoFacLib and CompanionSyncCoordinator looking for where the home screen's account state fails to update after import
- +8mIntervention · +8mDeveloper repeated the exact same bug description after the long investigation hadn't converged on a fixWhy: it was still just digging through code without a fix so I restated the bug to keep it focused
- +12mAgent did · +12mContinued investigating, focusing on how koinViewModel() resolves the singleton vs get()/getOrNull() and checking the Koin library version as a likely cause of stale ViewModel instances
- +14mOutcome · +14mSession ends mid-investigation: app runs on the emulator, but the home-screen refresh bug's root cause (suspected Koin viewmodel resolution) is identified without a fix yet applied
Next time I'd give the emulator setup skill explicit fallback steps for a full-storage situation so it doesn't need three rounds of poking at df/pm before wiping data. Manually confirming the emulator had booted and telling it to continue is what got the run unstuck after the boot script hung. The bug hunt itself ran long without a fix landing — repeating the bug description helped refocus it on the Koin viewmodel resolution theory, but I'd want to see the actual fix and a rerun before calling this done.
