MapComponent

[Bryan Buchanan]

In the Developer Guide, it says "The MapComponent uses a somewhat outdated tiling API which is not as rich as modern native maps." Can you elaborate on that, and whether it is still usable with a custom TiledProvider to use across all platforms (Android, iOS, UWP) ?

[Shai Almog]

We recommend most developers use the native maps implementation moving forward. Ideally we'll also add a fallback there that would use the web version of the API which is better maintained by Google. Most map providers are moving away from tiling API's for maps so doing that would be prudent.

[Bryan Buchanan]

My understanding (which may be incorrect) is that all the tooling around OpenStreetMap serves tiles. Do you know if it's possible to use custom data sources (i.e. your own  OpensStreetMap data server) with native maps ?

[Shai Almog]

No the native maps work differently (vectors).

[Bryan Buchanan]

OK - having done a bit of research, it appears I can run my own vector tile server:https://github.com/tilezen/vector-datasource/wiki/Mapzen-Vector-Tile-Service, and there is an OpenGL rendering library: https://github.com/tangrams/tangram-es

Is it feasible for me to think about using this in CN1 ?

[Steve Hannah]

On the Codename One side, that would have to be embedded as a peer component, and it would be a fair bit of work.  I simpler approach for client-side rendering, might be to port this library (http://wiki.openstreetmap.org/wiki/Kothic_JS) into Codename One.   That library looks quite small, and CN1 should support most of the necessary 2D drawing primitives to do the rendering in a cross-platform way. 

It all depends on what you're trying to achieve.  The native maps libs are quite good, so, in my mind, you'd have to have a good reason for trying avoid them.   Any other approach is likely to give "poorer" results than the native maps.
