我正在学习创建MapBox导航应用程序的教程。当我到达获得Route的点时，我复制整个代码部分，然后检查currentRoute类以查看我是否确实获得了路由，并且它返回了DirectionsRoute类的方向和其他调用，所以我假设我有准备好添加的路线。一切似乎都很好，直到我尝试将currentRoute添加到NavigationMapRoute。然后我收到错误java.lang.NoSuchMethodError: No direct method <init>(Ljava/lang/String;Lcom/mapbox/services/commons/geojson/FeatureCollection;Lcom/mapbox/mapboxsdk/style/sources/GeoJsonOptions;)V in class Lcom/mapbox/mapboxsdk/style/sources/GeoJsonSource; or its super classes (declaration of 'com.mapbox.mapboxsdk.style.sources.GeoJsonSource' appears in /data/app/MyApp-IHmaY_75jKlOywZrW4r3Ow==/base.apk)
我很困惑，因为当我完成所有设置时，我不希望在教程部分中打电话失败。我在这里错过了什么？ （代码取自https://www.mapbox.com/help/android-navigation-sdk/#calculate-and-draw-route） `
private void getRoute(com.mapbox.geojson.Point origin, com.mapbox.geojson.Point destination) {
NavigationRoute.builder()
.accessToken(Mapbox.getAccessToken())
.origin(origin)
.destination(destination)
.build()
.getRoute(new Callback<DirectionsResponse>() {
@Override
public void onResponse(Call<DirectionsResponse> call, Response<DirectionsResponse> response) {
// You can get the generic HTTP info about the response
Log.d(TAG, "Response code: " + response.code());
if (response.body() == null) {
Log.e(TAG, "No routes found, make sure you set the right user and access token.");
return;
} else if (response.body().routes().size() < 1) {
Log.e(TAG, "No routes found");
return;
}
currentRoute = response.body().routes().get(0);
// Draw the route on the map
if (navigationMapRoute != null) {
navigationMapRoute.removeRoute();
} else {
navigationMapRoute = new NavigationMapRoute(null, mapView, mapboxMap, R.style.NavigationMapRoute);
}
navigationMapRoute.addRoute(currentRoute);
}
@Override
public void onFailure(Call<DirectionsResponse> call, Throwable throwable) {
Log.e(TAG, "Error: " + throwable.getMessage());
}
});
}
此代码位于我的onCreate（）
中destinationPosition = com.mapbox.geojson.Point.fromLngLat(-122.269532,37.879842);
originPosition = com.mapbox.geojson.Point.fromLngLat(-122.258875, 37.865593);
getRoute(originPosition, destinationPosition);

答案 0 :(得分：2)
解决方案：从gradle文件中删除两行代码，然后再次同步，清理并构建。
implementation 'com.mapbox.mapboxsdk:mapbox-android-sdk:5.5.1'
implementation ('com.mapbox.mapboxsdk:mapbox-android-sdk:6.0.1@aar') {
