osmdroid地图只查看网格，可以在没有外部存储权限的情况下使用osmdroid？
osmdroid地图只查看网格，可以在没有外部存储权限的情况下使用osmdroid？
提问于 2019-10-30 11:26:48
我的osmdroid地图只显示一个空的网格，为什么会这样？
我在这里搜索了一些同样的问题，并尝试过，但我无法解决我的问题。我读过osmdroid需要对sdcard /外部存储的许可。我不能用这个吗？因为我的设备不支持外部存储或sdcard。
这是我的代码
super.onCreate(savedInstanceState);
Context context = getApplicationContext();
Configuration.getInstance().load(context, PreferenceManager.getDefaultSharedPreferences(context));
//Mapbox.getInstance(directmap.this, getString(R.string.access_token));
IConfigurationProvider provider = Configuration.getInstance();
File basePath = new File(getCacheDir().getAbsolutePath(), "osmdroid");
//provider.setUserAgentValue(BuildConfig.APPLICATION_ID);
provider.setOsmdroidBasePath(basePath);
File tileCache = new File(provider.getOsmdroidBasePath().getAbsolutePath(), "tile");
provider.setOsmdroidTileCache(tileCache);
setContentView(R.layout.activity_directmap);
ButterKnife.bind(this);
final Context context1 = getApplicationContext();
Configuration.getInstance().load(context1, PreferenceManager.getDefaultSharedPreferences(context1));
Configuration.getInstance().setUserAgentValue(BuildConfig.APPLICATION_ID);
mapView = findViewById(R.id.mapViewosm);
mapView.setTileSource(TileSourceFactory.MAPNIK);
mapView.setMultiTouchControls(true);
mapView.setBuiltInZoomControls(true);
// mapView = (MapView) findViewById (R.id.mapViewosm);
// button = (Button) findViewById(R.id.startButton);
roadManager = new GraphHopperRoadManager(getString(R.string.apikey), true);
manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
Objects.requireNonNull(getSupportActionBar()).setDisplayHomeAsUpEnabled(true);
route.setOnClickListener(this);
//mapView.onCre(savedInstanceState);
//mapView.getMapAsync(this);
startIcon = BitmapFactory.decodeResource(context.getResources(), R.drawable.ic_mark);
//ambil lokasi pendonatur
lat = -5.402213; //getIntent().getDoubleExtra("latitude", 0);,
lng = 105.264113;//getIntent().getDoubleExtra("longitude", 0);
setupOverlay();
setupMap();
addMarker();
}

setupMap();
addMarker();
}
private void setupMap() {
// setting tile map
// mapController = mapView.getController();
BingMapTileSource.setBingKey(getString(R.string.bingkey));
BingMapTileSource bingMap = new BingMapTileSource(null);
bingMap.setStyle(BingMapTileSource.IMAGERYSET_ROAD);
// menambah overlay ke dalam map
mapView.getOverlays().add(rotationGestureOverlay);
mapView.getOverlays().add(compassOverlay);
mapView.getOverlays().add(myLocationNewOverlay);
mapView.getOverlays().add(roadNodeMarkers);
//setting mapView
mapView.setTileSource(bingMap);
mapView.setTilesScaledToDpi(true);
mapView.setMinZoomLevel(1.0);
mapView.setMaxZoomLevel(21.0);
mapView.setMultiTouchControls(true);
mapView.setUseDataConnection(true);
mapView.getZoomController().setVisibility(CustomZoomButtonsController.Visibility.NEVER);
mapController.animateTo(new GeoPoint(-5.402213, 105.264093));
}
private void addMarker() {
Marker destMarker = new Marker(mapView);
destPoint = new GeoPoint(lat, lng);
destMarker.setPosition(destPoint);
destMarker.setTitle(getIntent().getStringExtra("title"));
destMarker.setSubDescription(getIntent().getStringExtra("username"));
destMarker.setIcon(getDrawable(R.drawable.ic_mark));
mapView.getOverlays().add(destMarker);
mapView.invalidate();
}这是我的清单

因此，您没有提到您正在使用的osmdroid或android的哪个版本，但是没有对配置设置做任何改动，它将默认为应用程序私有存储，应该按原样工作。它应该默认为/data/data/yourAppPackageName/osmdroid/
如果默认值不起作用(重置配置实例之后)，那么尝试设置上面描述的显式路径。
