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

java - 适用于Android的Tomtom Maps SDK无法加载图块-LMLPHP

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")
}




并且我已将APK添加到AndroidManifests文件中:


    <meta-data
        android:name="OnlineMaps.Key"
        android:value="<my-Key-here>" />



同样,将地图片段添加到.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()
    }

最佳答案

检查两个可能的点:


您的API密钥无效。请通过调用原始的TomTom Maps端点:https://api.tomtom.com/map/1/tile/basic/main/0/0/0.png?key=your_api_key来检查API密钥,如果看不到地图图块图像,请通过转到TomTom Developer Portal来注册新的API密钥,然后再次检查。
您的API密钥放置在AndroidManifest.xml文件内的错误位置。确保将其放置在<application>标记内,在<activity>标记旁边。
