Uploading Custom Google Maps created in App to a web page

I am currently creating an android app in which users can add overlay items to a Google map. The goal is to have these customized maps be saved and uploaded to an internet community. I can't figure out how to do this, but would really appreciate learning how to either embed the app (and thus the customized map) into a web page or just s开发者_如何学JAVAave the map and upload it. Thanks, Sam

Have a look at KML it's a xml markup language to exchange geospatial data ("maps"). Google Earth, Google Maps and other applications can read, write and display kml files.
