我正在使用适用于 android 的 Skobbler Map API，到目前为止它一直非常好。按照官方的“如何”，我已经能够将地图实现到我的应用程序中。比我可以让应用程序下载地图并离线使用它。

但我的目标是有一个预先捆绑的离线地图。我已经完成了“如何”中的所有步骤，但它不起作用，我不断收到错误

似乎只要我将离线地图插入 zip，就会生成错误。

这是我的主要活动：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        SKLogging.enableLogs(true);
        File externalDir = getExternalFilesDir(null);

        // determine path where map resources should be copied on the device
        if (externalDir != null) {
            mapResourcesDirPath = externalDir + "/SKMaps/";
        } else {
            mapResourcesDirPath = getFilesDir() + "/SKMaps/";
        }

        new SKPrepareMapTextureThread(this, mapResourcesDirPath, "SKMaps.zip", this).start();
    }

    @Override
    public void onMapTexturesPrepared(boolean prepared) {
        if(prepared){
            initializeLibrary();
            startActivity(new Intent(MainActivity.this, MapActivity.class));
        }else{
            Toast.makeText(MainActivity.this, "Map resources are not prepared", Toast.LENGTH_SHORT).show();
        }
    }

    /**
     * Initializes the SKMaps framework
     */
    private void initializeLibrary() {
        SKMapsInitSettings initMapSettings = new SKMapsInitSettings();
        // set path to map resources and initial map style
        initMapSettings.setMapResourcesPaths(mapResourcesDirPath,
                new SKMapViewStyle(mapResourcesDirPath + "/outdoorstyle/", "outdoorstyle.json"));

        // EXAMPLE OF ADDING PREINSTALLED MAPS
        initMapSettings.setPreinstalledMapsPath(mapResourcesDirPath + "/PreinstalledMaps");
        //initMapSettings.setConnectivityMode(SKMaps.CONNECTIVITY_MODE_OFFLINE);

        SKMaps.getInstance().initializeSKMaps(this, initMapSettings, API_KEY);
    }

和我的地图活动：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_map);

        SKMapViewHolder mapViewGroup = (SKMapViewHolder) findViewById(R.id.map_surface_holder);
        mapView = mapViewGroup.getMapSurfaceView();
        mapView.centerMapOnPosition(new SKCoordinate(19.8171, 41.3294));
    }

    @Override
    protected void onPause() {
        super.onPause();
        mapView.onPause();
    }

    @Override
    protected void onResume() {
        super.onResume();
        mapView.onResume();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        SKMaps.getInstance().destroySKMaps();
        android.os.Process.killProcess(android.os.Process.myPid());
    }

谢谢，

检查包含以下文件的 SKMaps.zip：

SKMaps/res/xhdpi/icon_map_popup_arrow.png
SKMaps/res/xhdpi/icon_map_popup_navigate.png

如果没有，您应该添加它们。

尝试使用 

new SKPrepareMapTextureThread(this, new File(yourMapPathHere).getParent(), "SKMaps.zip", this).start();
