From 15baafc9bebcfed2600548d2a05bf6f5e792bb8e Mon Sep 17 00:00:00 2001 From: n0tst3v3 Date: Wed, 19 Aug 2026 04:56:19 -0600 Subject: [PATCH] refactor(map): split the map screen into four focused classes MapActivity had grown to 4,800 lines and was editing itself into corruption - the field block had picked up seventeen duplicate declarations of showNormalizationChanges, and that name was being used for both the CheckBox widget and the boolean state it toggles, which is what the compiler was actually failing on. Fix the collision the way the class already handles the same pattern elsewhere (showNormalized/normalizedMode): the widget is showChanges, the state stays showNormalizationChanges. Then move the bulk out of the activity: HistoryNormalizer the GPS cleanup engine, its caches, thresholds and the LocationPoint reflection helpers MapExporter CSV export, including the 695-line writer and the file-picker round trip MapHtmlBuilder the Leaflet page, markers, trails and popups MapFormat date/reason/colour/HTML/JS/CSV escaping shared by all three The activity keeps the UI - onCreate, the filter panel, pickers and sensors - and feeds the builders through a Filters snapshot, an Options struct and a two-method DataSource interface, so none of the extracted classes reach back into its widgets. Behaviour is unchanged. Also drops pendingExportMode, which was written in two places and never read.
