我正在尝试将TomTom地图添加到使用 构建的 android 应用程序中Kotlin,但它给了我错误Tomtom Maps SDK for android failed to load tile并显示一个空地图,如下图所示:

tomtom 地图无法加载图块

这是我正在使用的文件和详细配置:

  • 在项目级别的 Gradle 文件中,我有:
    allprojects {
    repositories {
        google()
        jcenter()
        maven {
            url "https://maven.tomtom.com:8443/nexus/content/repositories/releases/"
        }
    }
}

  • 在应用程序级别的 Gradle 文件中,我有:

    dependencies {
    implementation("com.tomtom.online:sdk-maps:2.4244")
}

  • 我已将其添加APKAndroidManifests文件中:
    <meta-data
        android:name="OnlineMaps.Key"
        android:value="<my-Key-here>" />
  • 此外,地图片段被添加到 .XML 文件中:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MapActivity">

    <fragment
        android:id="@+id/mapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:name="com.tomtom.online.sdk.map.MapFragment"
        />


</androidx.constraintlayout.widget.ConstraintLayout>
  • 最后,这是用于启动地图的 Kotlin 代码:

    //lateinit late initialization of non-null type variables
    private lateinit var map: TomtomMap
    private lateinit var fusedLocationClient: FusedLocationProviderClient
    private lateinit var lastLocation: Location

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_map)
        val mapFragment = supportFragmentManager
            .findFragmentById(R.id.mapFragment) as MapFragment
        mapFragment.getAsyncMap(this)
        fusedLocationClient = LocationServices.getFusedLocationProviderClient(this)

    }


    companion object {
        private const val LOCATION_PERMISSION_REQUEST_CODE = 101
    }
    private fun setUpMap() {
        if (ActivityCompat.checkSelfPermission(this,
                android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(this,
                arrayOf(android.Manifest.permission.ACCESS_FINE_LOCATION), LOCATION_PERMISSION_REQUEST_CODE)
            return
        }
        map.isMyLocationEnabled = true
        fusedLocationClient.lastLocation.addOnSuccessListener(this) {
                location ->
            if (location != null){
                lastLocation = location
                val currentLatLng = LatLng(location.latitude, location.longitude)
                val balloon = SimpleMarkerBalloon("You are Here")
                map.addMarker(MarkerBuilder(currentLatLng).markerBalloon(balloon))
                map.centerOn(CameraPosition.builder(currentLatLng).zoom(7.0).build())

            }

        }
    }


    override fun onMapReady(@NonNull tomtomMap: TomtomMap) {
        this.map = tomtomMap
        setUpMap()
    }

两个可能的检查点:

  • 您的 API 密钥无效。请通过调用原始 TomTom 地图端点检查您的 API 密钥:https ://api.tomtom.com/map/1/tile/basic/main/0/0/0.png?key=your_api_key如果您不能查看地图图块图像 - 前往TomTom 开发者门户注册您的新 API 密钥并再次检查。

  • 您的 API 密钥放置在 AndroidManifest.xml 文件中的错误位置。确保将其放置在<application>标签内,标签旁边<activity>
