私は Android 用の Skobbler Map API を使用していますが、これまでのところ非常に優れています。公式の「ハウツー」に従って、アプリにマップを実装することができました。アプリにマップをダウンロードさせてオフラインで使用するよりも。
しかし、私の目標は、事前にバンドルされたオフライン マップを用意することです。「ハウツー」のすべての手順を実行しましたが、うまくいきません。エラーが発生し続けます

zip にオフライン マップを挿入するとすぐにエラーが発生するようです。
ここに私のMainActivityがあります:
@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);
}
そして私の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());
}
ありがとうございました、
