Skobbler Android Pre-bundled Error

Question

I am working with the Skobbler Map API for android and it has been very good so far. Following the official “How to” i have been able to implement the map to my app. Than I could make the app download the map and use it offline.

But my goal is to have a pre bundled offline map. I have done all the steps from the “how to” but it won’t work, I keep getting the error

It seems that as soon as I insert the offline map to the zip, the error is generated.

Here is my MainActivity:

@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);
    }

and my MapActivity:

@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());
    }

Thank you,

Answer 1

Try to init your map with

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

Answer 2

Check your SKMaps.zip containing following files:

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

If not, you should add them.
