Code examples

private val tileRegionId = "Washington DC"
private val tileStore = TileStore.create()
private val descriptors = listOf(OfflineSearchEngine.createTilesetDescriptor())
// Working if coordinates are in US, UK, Mexico, e.g:
// private val dcLocation Point.fromLngLat(-77.0339911055176, 38.899920004207516)

// Not working if coordinates are in HK, Japan, China Mainland
private val dcLocation = Point.fromLngLat(127.024612, 37.532600) 

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

    searchEngine = OfflineSearchEngine.create(
        OfflineSearchEngineSettings(
            tileStore = tileStore
        )
    )

    searchEngine.addEngineReadyCallback(engineReadyCallback)

    searchEngine.addOnIndexChangeListener(object : OfflineSearchEngine.OnIndexChangeListener {
        override fun onIndexChange(event: OfflineIndexChangeEvent) {
            if (event.regionId == tileRegionId && (event.type == EventType.ADD || event.type == EventType.UPDATE)) {
                logI("SearchApiExample", "$tileRegionId was successfully added or updated")

                searchRequestTask = searchEngine.reverseGeocoding(
                    OfflineReverseGeoOptions(center = dcLocation),
                    searchCallback
                )
            }
        }

        override fun onError(event: OfflineIndexErrorEvent) {
            logI("SearchApiExample", "Offline index error:", event)
            onFinished()
        }
    })
}

Observed behavior and steps

In OfflineSearchKotlinExampleActivity.kt the IndexChangeListener will not be invoked if change the coordinates to HK, Japan, China Mainland, e.g:

private val dcLocation = Point.fromLngLat(114.1547347, 22.2846202) <== HK
private val dcLocation = Point.fromLngLat(127.024612, 37.532600) <== Japan

But the orginal coordinates provided by sample works, and tried GPS in Maxico and UK also works.

Expected behavior

The IndexChangeListener should be invoked, and tile should be able to load, and then can perform offline search.
