feat(upgrade) : migrate to Maps 3D SDK 16.0.0 and update OnMap3DClickListener API

[LoyalAbbas]

Summary

Updates the Google Maps 3D Android samples repository to Google Maps 3D SDK 16.0.0, migrating setMap3DClickListener callbacks to the new Map3DClickEvent signature and updating XML layout attributes from map3d:mode to map3d:mapMode.

Key Changes

1. SDK Version & Build Configuration

• gradle/libs.versions.toml: Bumped playServicesMaps3d from 0.2.2 to 16.0.0.
• settings.gradle.kts: Enabled use_local_maven default for testing against local SDK artifacts.

2. OnMap3DClickListener Migration ((event: Map3DClickEvent) -> Boolean)

Migrated all setMap3DClickListener call sites from (location: LatLngAltitude, placeId: String?) -> Unit to (event: Map3DClickEvent) -> Boolean:

• Compose Wrapper (maps3d-compose):
  • Updated GoogleMap3D.kt to unpack event.location and event.placeId from Map3DClickEvent, invoke onPlaceClick or fall back to onMapClick, and return true when handled (false otherwise).
• Sample Apps (ApiDemos, ComposeDemos, maps3d-compose-demo, PlacesUIKit3D):
  • Updated Kotlin and Java MapInteractionsActivity across ApiDemos, ComposeDemos, and maps3d-compose-demo.
  • Updated Kotlin and Java MarkersActivity in ApiDemos to dismiss any active popover on map click and return whether a popover was dismissed.
  • Updated PlacesUIKit3D/MainActivity.kt to select clicked places and return true when event.placeId is non-empty.
• Snippets & Documentation:
  • Updated Kotlin and Java PlaceSnippets (snippets/kotlin-app and snippets/java-app).
  • Updated Kotlin and Java code samples in Maps3DSamples/ApiDemos/migration_guide.md.

3. XML Layout Attribute Migration (map3d:mode -> map3d:mapMode)

• Replaced deprecated map3d:mode XML attribute with map3d:mapMode across Map3DView layouts in:
  • Maps3DSamples/ApiDemos/common/src/main/res/layout/ (activity_camera_controls.xml, activity_cloud_styling.xml, activity_common_map.xml, activity_hello_map.xml, activity_map_interactions.xml)
  • PlacesUIKit3D/src/main/res/layout/activity_main.xml
  • .gemini/skills/android-maps3d-sdk/assets/samples/ (views_java/activity_main.xml, views_kotlin/activity_main.xml)
