I need a library/framework that i can use to store a custom map(as tiles) locally on android and show it as a map . I would like to get a real-time position of an object(Point data - it's within a building ) from the server ( a compatible server of course) and project it on my app . My question is - Is there a library - Server combination that can do this . I'm still reading and learning about different types of servers and libraries, so can you please be elaborate
The Google Maps Android API allows you to easily add your own, custom, tiles to the map.
Essentially, you add a TileOverlay instance to your map, which uses your custom TileProvider implementation to provide the tile images. See the API docs for TileOverlay.
In our software, Mappt for Android tablets, we have used the tiling system to load both local and remote tiles. The ability to load tiles from local storage works great offline.
With regards to real-time tracking of an object, depending on your server and specific requirements, you could implement a small site that uses SignalR to receive and rebroadcast object position updates. We have used SignalR to great effect for this in the past, albeit not using Android clients (ours were web-based).
I found an article here that describes how to interface Android clients with SignalR.
