这里地图显示蓝色地球使用android studio中的最新SDK，地图不出现

Question

我运行地图提供的示例应用程序，但它只是显示一个蓝色地球。地图没有出现，我不知道我犯了什么错误。我提到了Maps文档和GitHub。

这里是我的代码：

package com.here.android.example.routing; 

import android.app.Activity; 
import android.graphics.Color; 
import android.os.Bundle; 

import com.here.android.mpa.common.GeoCoordinate; 
import com.here.android.mpa.common.Image; 
import com.here.android.mpa.common.MapEngine; 
import com.here.android.mpa.common.OnEngineInitListener; 
import com.here.android.mpa.mapping.Map; 
import com.here.android.mpa.mapping.MapFragment; 
import com.here.android.mpa.mapping.MapMarker; 
import com.here.android.mpa.mapping.MapView; 
import com.here.android.mpa.mapping.customization.CustomizableScheme; 
import com.here.android.mpa.mapping.customization.CustomizableVariables; 
import com.here.android.mpa.mapping.customization.ZoomRange; 
import com.here.android.mpa.odml.MapLoader; 
import com.here.odnp.util.Log; 

import java.util.List; 



public class BasicMapActivity extends Activity { 

    // map embedded in the map fragment 
    private Map map = null; 
    MapView mapView = null; 


    // map fragment embedded in this activity 
// private MapFragment mapFragment = null; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     mapView = (MapView) findViewById(R.id.ext_mapview); 
     MapEngine.getInstance().init(this, engineInitHandler); 
    } 

    private OnEngineInitListener engineInitHandler = new OnEngineInitListener() { 
     @Override 
     public void onEngineInitializationCompleted(Error error) { 
      if (error == Error.NONE) { 
       map = new Map(); 


       // more map settings 
       map.setProjectionMode(Map.Projection.GLOBE); // globe projection 
       map.setExtrudedBuildingsVisible(true); 
       map.setLandmarksVisible(false); 
       mapView.setMap(map); 

       // MapLoader.getInstance().addListener(mapLoaderHandler); 

       // update packages and get installation state 
       MapLoader.getInstance().getMapPackages(); 
       // more map initial settings 

      } else { 
       Log.e("get", "ERROR: Cannot initialize MapEngine " + error); 

      } 
     } 
    }; 

    @Override 
    public void onResume() { 
     super.onResume(); 
     MapEngine.getInstance().onResume(); 
     if (mapView != null) { 
      mapView.onResume(); 
     } 
    } 

    @Override 
    public void onPause() { 
     if (mapView != null) { 
      mapView.onPause(); 
     } 
     MapEngine.getInstance().onPause(); 
     super.onPause(); 
    } 
} 

摇篮依赖性文件

dependencies { 
     compile(name: 'HERE-sdk', ext: 'aar') 

     compile fileTree(include: ['*.jar'], dir: 'libs') 
     compile 'com.android.support:appcompat-v7:23.4.0' 

    }

Answer 1

你可以尝试设置地图中心，

public void setCenter (GeoCoordinate point, Animation animation) 

或

public void setCenter (GeoCoordinate point, Animation animation, double level, float orientation, float tilt) 

，您可以用

GeoCoordinate (double latitude, double longitude) 

Answer 2

创建会有地理座标删除线MapLoader.getInstance（）。getMapPackages（）。这使引擎处于地图数据下载状态。而你的代码目前不处理任何地图加载器回调，因此它停留在中间状态。
