Reduce location resource usage: economy mode by default, lifecycle throttling

2026-05-19T22:00:37+00:00

- Start LocationService at ECONOMY (5 s, PRIORITY_BALANCED_POWER_ACCURACY) instead of FULL (1 Hz, PRIORITY_HIGH_ACCURACY); promote to FULL only while a track is actively recording and demote back when recording stops - Use PRIORITY_BALANCED_POWER_ACCURACY for ECONOMY and ANCHOR_WATCH modes so the GPS chip idles and network/passive sources handle light-duty fixes - Add ACTION_START_ECONOMY / ACTION_START_FULL intents so MainActivity can drive mode transitions from lifecycle callbacks - onPause: drop to ECONOMY if not recording or anchor-watching; onResume: restore the appropriate mode so the first visible frame has a fresh rate - Stop-anchor-watch now returns to ECONOMY instead of FULL (anchor drop rarely coincides with active track recording) - Remove ACCESS_BACKGROUND_LOCATION from manifest — the foreground service with foregroundServiceType="location" already covers background access - Add 5 m minimum-distance filter to DeviceGpsProvider so stationary devices don't generate spurious location callbacks https://claude.ai/code/session_01YUbuZNDAoLea4cf9UGQ9qn

- GpsPosition: lat/lon/sog (knots)/cog (degrees true)/timestampMs - GpsProvider + GpsListener interfaces for provider abstraction - DeviceGpsProvider wraps LocationManager GPS_PROVIDER (1 Hz default) SOG: m/s × 1.94384 knots; fix-lost timeout 10s - FakeGpsProvider + 9 passing JVM unit tests (no Android deps) Co-Authored-By: Claude Sonnet 4.6
