Jetpack Compose Android App to record Electric car journeys and charging stats
It's been a while since I tried Android development.
- Really getting confused about ViewModels, init {} blocks, LaunchedEffects... I'm not getting the data I expect when I expect it
- Ability to abort a charge event
- Prevent editing of starting values on active charge event
- Fix main menu still showing charge event after it's finished
- Correctly handle startup if vehicles exist but SharedPreferences does not - or maybe store selected vehicle etc in DB instead?
- Saving total cost of a charge event
- need to parse input string like "1.50" correctly, currently it fails and returns 0
- Text styling on real device - black on black is hard to read...
- Very inconsistent behaviour moving between screens when charging
- Remove all references to costs; it's not always practical to know what the cost will be, chargers often don't report this
- Set up database migrations so that I can avoid wiping the DB
- field validation - really required for currency and percentages
- this did not go well when I tried to do it at the composable text input level, so probably needs to happen at the viewmodel - which would mean hoisting the fields into the VM?
- cross-field validation at viewmodel level?
- Charging screen improvements
- Should persist across process death
- Check if charge is in progress on startup
- Restore the timer correctly based on the charge start time
- Handle back navigation when charge event is saved (e.g from history screen)
- Use
Scaffoldfor layout
- Add better navigation - might come with
Scaffold? - Enable switching between different vehicles - could be useful to keep dev separate from real, now that the app works in a basic way
- cross-field validation at ViewModel level?
- Charging screen improvements
- Should persist across process death
- Check if charge is in progress on startup
- [-] Restore the timer correctly based on the charge start time
- charge history table improvements
- charge history graphs
- Journey recording screens and model
- Android Auto integration
- Add a photograph of the cars for easy identification
- Edit car details
- Delete vehicle and all associated events, images etc
