Next Gen SimpleTrack

Capture ideas of a rework/refactor of SimpleTrack. The goals of a refactoring are to eliminate known errors and deficiencies of the current version of SimpleTrack (V 1.2.X).

Goals:

Simply code base over 1.2
Reduce Android OS events preventing sending of positions
Work with latest OS for power and schedule reasons

Design Axioms:

Minimize computation
Minimize network connections, work with scheduler, consolidate to single server connection
All pending work stored in SQLite, points to upload will be in file.
Vehicles/Projects in SQLite (to support drop downs)
User credentials in SQLite
User preferences in shared preferences
All data in app private storage (uninstall removes everything)
- Use Firebase cloud storage to simplify configuration, all same google log in?
UI ONLY sets values in DB/Shared Prefs, all business logic in service.
Target Android 5 (Lollipo 22) as minimum usable SDK.

Items to do:

All core functionality enclosed in an Android Service
- Collection of locations and upload of same
- Collection of gpsstat and upload of same
- Download vehicle save as local config
- Download of application controls configuration
- Service with work with proper OS scheduling of uploads and other work
Refactor to remove
- Cycle-line and associated statistics calculations
- Simplify configuration controls to only drive application - no project support
- Remove AGTEK_Lib from build of ST
- Complete migration from Crashlytics to Firebase
