Osmdroid Offline-Modus Update Kacheln nach dem Zoom
Ich entwickle eine Android-App, die Osmdroid verwendet, um die Karten im Offline-Modus anzuzeigen. Ich habe ein Problem, wenn ich in die Karte hinein- oder herauszoomen oder die eingebauten Zoom-Steuerelemente verwenden möchte. Wenn ich in die Karte hinein zoome, werden Kacheln nicht immer korrekt gerendert, und wenn ich herauszoome, sind manchmal einige graue Kacheln in der Karte, manchmal wird alles in Ordnung gerendert. Es hängt nicht mit dem Ort zusammen, der auf der Karte angezeigt wird. Meine Kartenkacheln werden in einer Osmdroid-Zip-Datei mit der Mapnik-Quelle im Ordner / mnt / sdcard / osmdroid gespeichert. Ich benutze Osmdroid-3.0.7.
Daher ist jede Hilfe willkommen.
