Getting a working mobile-SDK key from 2GIS turned out to require a
sales-mediated B2B process (Platform Manager subscription, demo keys
explicitly excluded from mobile SDK use per their own docs), not a
quick self-serve signup. Swapped to osmdroid instead: free, no API
key or account, works immediately.
CityMapView (replacing DgisMapView/DgisSdkProvider) wraps osmdroid's
View-based MapView via AndroidView, forwarding lifecycle events, with
markers for the user's location and each nearby place. Configured
required OSM tile-usage-policy user agent + app-private tile cache in
GuideCityApp. Removed the now-unused DGIS_API_KEY plumbing and the
arm64-only ABI filter (osmdroid has no heavy native libs, so it's not
needed) — APK is back down to ~19.6MB from ~69MB.
Verified: testDebugUnitTest passes, assembleDebug produces a working
APK, sent via the Telegram bot (previously blocked by its 50MB limit
with the 2GIS build).

Added the actual ru.dgis.sdk:sdk-map + compose-map dependencies (from
https://artifactory.2gis.dev/sdk-maven-release) instead of the Canvas
placeholder guess. Verified the exact API surface by downloading the
AARs directly and inspecting classes with javap (DGis.initialize,
MapOptions, MapComposableState/MapComposable, CameraPosition/GeoPoint)
rather than relying on possibly-stale docs.
DgisSdkProvider lazily calls DGis.initialize() once per process,
catching failure so a missing key doesn't crash the app; DgisMapView
renders the real MapComposable when that succeeds, falling back to
the old placeholder canvas otherwise.
Important finding: the existing DGIS_API_KEY (2GIS's public REST/JS
API key format) does NOT work with this native SDK. It requires a
separate dgissdk.key file issued per-app-package from dev.2gis.com,
placed in app/src/main/assets/ (gitignored). Documented in README.
Without it the app still runs fine on the placeholder map.
Also restricted ndk.abiFilters to arm64-v8a — the SDK's native libs
otherwise balloon the APK from ~19MB to ~190MB.
Verified: testDebugUnitTest passes, assembleDebug produces a working
(arm64-only, ~69MB) APK. Not runtime-verified against a real map key
or device — no emulator/device available in this environment.

Log.d/i/w/e calls covering location resolution, TTS lifecycle and
errors, nearby/search network calls and their failure paths, and
screen-level state transitions. OkHttp's logging interceptor now
routes through Log (tag "OkHttp") instead of println for consistent
filtering. Enabled testOptions.unitTests.isReturnDefaultValues so
android.util.Log calls don't crash plain JVM unit tests.
Added mockk + kotlinx-coroutines-test and a GuideViewModelTest suite
covering the load-success, load-failure, and retry paths — including
a regression test for the infinite-spinner bug (isLoading must clear
and errorMessage must be set on a failed nearby-search call, not left
hanging). Verified: ./gradlew testDebugUnitTest passes (4/4).

Full app scaffold wired to the backend: onboarding, content-length
picker, map screen (permission flow + text-search fallback), guide
screen with a swipeable place-card stack driven by on-device TTS
narration and a 60s re-scan loop, place detail screen with
mute/favorite controls, favorites (Room-backed), and settings.
Hilt for DI, Retrofit+kotlinx.serialization for the API client,
DataStore for onboarding/content-length prefs, FusedLocationProviderClient
for location. The 2GIS MapKit integration is isolated behind
map/DgisMapView.kt (currently a placeholder) since its exact Maven
coordinates need confirming from the 2GIS developer portal.
Verified by actually building it: installed a minimal Android SDK
(platform 34 + build-tools, no emulator) and JDK 17 locally, then ran
:app:compileDebugKotlin, :app:assembleDebug (produced a real debug
APK), and :app:lintDebug (0 errors, 44 non-blocking warnings, mostly
"newer dependency version available"). Caught and fixed two real bugs
this way: a wrong Maven artifact for the Retrofit kotlinx.serialization
converter, and missing ExperimentalMaterial3Api opt-in.
