The download is already complete and the tiles are saved. The style will work from HTTP cache until it expires. + + 2. In the `onComplete` callback of `startDownload()`, after `markCompleteWithMaplibreId()`, call `fetchAndCacheStyleJson(regionId)`. This must be inside the `viewModelScope.launch` block that's already there in `onComplete`. + + 3. Use `java.net.URL(url).readText()` wrapped in `withContext(Dispatchers.IO)` for the HTTP fetch.

Add the necessary import for `kotlinx.coroutines.withContext` if not already present. + + **Important:** Do NOT add the style fetching to the `onCreated` callback.

Modify the `getMapStyle()` function's `hasOffline` branch to check for a locally cached style JSON first: + ```kotlin + hasOffline -> { + // Check if any completed region has a locally cached style JSON + val regionWithStyle = offlineMapRegionRepository.getFirstCompletedRegionWithStyle() + val stylePath = regionWithStyle?.localStylePath + + if (stylePath != null && java.io.File(stylePath).exists()) { + Log.d(TAG, "Using offline maps with local style JSON: $stylePath") + MapStyleResult.OfflineWithLocalStyle(stylePath) + } else { + // Fallback to HTTP style URL (works if HTTP cache hasn't expired) + Log.w(TAG, "No local style JSON found, falling back to HTTP style URL") + MapStyleResult.Offline(DEFAULT_STYLE_URL) + } + } + ``` + + 3. The `getFirstCompletedRegionWithStyle()` method was added to the repository in Plan 01.

Update the `allowNetwork` check: + ```kotlin + val allowNetwork = styleResult is MapStyleResult.Online || styleResult is MapStyleResult.Rmsp + ``` + This already works because `OfflineWithLocalStyle` is neither `Online` nor `Rmsp`, so `allowNetwork` will be `false`.

After extended offline periods, **MapLibre's HTTP cache for style JSON expires** (respecting HTTP cache headers), leaving the library unable to resolve layer definitions needed to render tiles.

No new dependencies required. + +## Architecture Patterns + +### Current Code Path (Flawed) + +The current offline code path in `MapTileSourceManager.kt`: + +```kotlin +// Lines 123-128 in MapTileSourceManager.kt +hasOffline -> { + // Load the online style URL - MapLibre will serve cached tiles + // without making network requests for areas covered by offline maps + Log.d(TAG, "Using offline maps (loading style for cached tile access)") + MapStyleResult.Offline(DEFAULT_STYLE_URL) +} +``` + +And in `MapScreen.kt`: + +```kotlin +// Lines 331-332 +is MapStyleResult.Online -> Style.Builder().fromUri(styleResult.styleUrl) +is MapStyleResult.Offline -> Style.Builder().fromUri(styleResult.styleUrl) +``` + +**Problem:** Both online and offline modes use `fromUri()` with the same HTTP URL. This works initially because MapLibre caches the style JSON via HTTP, but the cache expires based on HTTP headers. The user's bug report confirms this: after "some days" offline, the map shows only the background layer. + +### Recommended Pattern: Local Style JSON with Offline Mode + +**Pattern 1: Generate and Cache Style JSON During Download** + +When downloading an offline region via MapLibre OfflineManager: + +```kotlin +// During download in OfflineMapDownloadViewModel +fun downloadRegion(...) { + mapLibreOfflineManager.downloadRegion( + // ... download parameters ... + onCreated = { regionId -> + // 1. Fetch the HTTP style JSON once during download + val styleJson = fetchAndCacheStyleJson(DEFAULT_STYLE_URL) + + // 2. Save it locally for offline use + val styleFile = File(context.filesDir, "offline_styles/$regionId.json") + styleFile.writeText(styleJson) + + // 3. Store the local path in the database + offlineMapRegionRepository.updateStylePath(regionId, styleFile.absolutePath) + } + ) +} +``` + +**Pattern 2: Load Local Style JSON When Offline** + +Modify `MapTileSourceManager.kt` to return the local style path: + +```kotlin +hasOffline -> { + // Get the first completed region (or region covering current location) + val region = offlineMapRegionRepository.getCompletedRegions().first().firstOrNull() + val stylePath = region?.localStylePath + + if (stylePath != null && File(stylePath).exists()) { + Log.d(TAG, "Using offline maps with local style JSON") + MapStyleResult.OfflineWithLocalStyle(stylePath) + } else { + // Fallback to HTTP style if no local style available + Log.w(TAG, "No local style found, falling back to HTTP URL") + MapStyleResult.Offline(DEFAULT_STYLE_URL) + } +} +``` + +And update `MapScreen.kt` to handle the new result type: + +```kotlin +when (styleResult) { + is MapStyleResult.Online -> Style.Builder().fromUri(styleResult.styleUrl) + is MapStyleResult.OfflineWithLocalStyle -> { + val styleJson = File(styleResult.localStylePath).readText() + Style.Builder().fromJson(styleJson) + } + is MapStyleResult.Offline -> Style.Builder().fromUri(styleResult.styleUrl) // fallback +} +``` + +### Alternative Pattern: Bundle Style JSON in Assets + +For simpler implementation, bundle a copy of the style JSON in the app's assets directory: + +```kotlin +// In MapTileSourceManager.kt +hasOffline -> { + // Use bundled style JSON from assets + MapStyleResult.OfflineWithAssetStyle("offline_map_style.json") +} + +// In MapScreen.kt +is MapStyleResult.OfflineWithAssetStyle -> { + val styleJson = context.assets.open(styleResult.assetPath).bufferedReader().use { it.readText() } + Style.Builder().fromJson(styleJson) +} +``` + +This approach is simpler but requires updating the bundled style manually when the tile source changes. + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| Style JSON caching | Custom cache with expiration logic | Local file storage with JSON serialization | HTTP cache expiration is the root cause; avoid relying on it | +| MBTiles generation | Custom tile packer | MapLibre OfflineManager API | Already handles tile downloads, deduplication, and storage efficiently | +| Offline region management | Custom region database | OfflineMapRegionRepository + OfflineManager | Already tracks regions, status, and provides Room-based querying | +| Style JSON fetching | Manual HTTP requests | OkHttp/Retrofit with single-shot call | Already in the project, handles retries and errors properly | + +**Key insight:** The existing `OfflineMapStyleBuilder.kt` can generate style JSON, but it's designed for `mbtiles://` protocol sources (lines 142-143). The current OfflineManager approach stores tiles in MapLibre's internal database, which are served automatically when the style references them—no `mbtiles://` needed. The issue is the style JSON itself not being available offline, not the tile storage mechanism. + +## Common Pitfalls + +### Pitfall 1: Assuming MapLibre Caches Style JSON Forever +**What goes wrong:** The app loads the HTTP style URL in offline mode, expecting MapLibre to serve it from cache indefinitely. + +**Why it happens:** MapLibre respects HTTP cache headers (Expires, Cache-Control, max-age). The OpenFreeMap Liberty style likely has cache headers that expire after days/weeks. + +**How to avoid:** Store the style JSON locally as a file, bypassing HTTP cache expiration entirely. Generate and save it during the initial offline map download. + +**Warning signs:** User reports map working initially after download, then failing after "some days" offline. Logs show "Applying style: g" (ProGuard-obfuscated) and "Creating new source and layers with 0 features", indicating the style loaded but has no tile sources defined. + +### Pitfall 2: Using `Style.Builder().fromUri()` for Offline Styles +**What goes wrong:** The code uses the same `fromUri()` method for both online and offline modes, which always makes a network request (or checks HTTP cache). + +**Why it happens:** Misunderstanding of MapLibre's style loading: `fromUri()` is for HTTP/HTTPS URLs, `fromJson()` is for local JSON strings. + +**How to avoid:** Use `Style.Builder().fromJson(styleJsonString)` when loading offline styles. The JSON string can be read from a local file or embedded in assets. + +**Warning signs:** Network logs show HTTP requests for style JSON even when `MapLibre.setConnected(false)` is called. The app relies on HTTP cache fallback instead of truly offline loading. + +### Pitfall 3: Not Testing Extended Offline Periods +**What goes wrong:** Offline maps work immediately after download but fail after days/weeks offline. + +**Why it happens:** HTTP cache headers are time-based. Testing immediately after download doesn't reveal expiration issues. + +**How to avoid:** +1. Test with device in airplane mode for multiple days +2. Manually clear MapLibre's ambient cache: `OfflineManager.getInstance(context).clearAmbientCache()` +3.
