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“操作方法”,我已经能够将 map 应用到我的应用程序中。比我可以让应用程序下载 map 并离线使用它。

但我的目标是拥有一个预 bundle 的离线 map 。我已经完成了“操作方法”中的所有步骤,但它不起作用,我不断收到错误

似乎我一将离线 map 插入zip,就产生了错误。

这是我的 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);
}

和我的 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());
}

谢谢,

最佳答案

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。
