Osmdroid modo sin conexión actualizar mosaicos después de zoom
Estoy desarrollando una aplicación para Android que utiliza Osmdroid para mostrar los mapas en modo sin conexión. Tengo un problema cuando quiero acercar o alejar la imagen al pellizcar el mapa o al usar los controles integrados de zoom. Cuando amplío el mapa, los mosaicos del mapa no siempre se procesan correctamente y cuando alejé el zoom, a veces hay algunos mosaicos grises en el mapa, a veces todo está bien. No está relacionado con la ubicación que se muestra en el mapa. Mis mosaicos de mapas se almacenan en un archivo zip de osmdroid con la fuente de Mapnik en la carpeta / mnt / sdcard / osmdroid. Estoy usando osmdroid-3.0.7.
Por lo tanto, cualquier ayuda es bienvenida.
Vea mi código a continuación (mis inclusiones no están incluidas aquí en el código):
