android - OSMDroid Offline map with zip from custom server -

i'm having hard time osmdroid working our custom tile server. i'm getting our tiles in zip file has following structure: zoomlevel/y/x

i've tried unzipping zip osmdroid/tiles folder , osmdroid/tiles/mapnik folder none of them seem work. think need use filebasedtilesource don't know put in aname , url part of method.

i'm trying download specific areas zip file use in offline situations, on google maps works want try out osmdroid , see of performance better.

can give me pointers on how working?

zip archives osmdroid must have following structure {source}/z/x/y.{extension}

then tell osmdroid use tile source name matches {source}. should automatic.

also, consider using sqlite database, faster
