Plugins - auto download dedtination points

Is it possible to code plugin that will download destination points from my company server and automatically start navigation?
In company we prepare deatination addresses for delivery goods, osmand installed in truck tablet automatically downloads destinations and then auto start navigation. Is it possible using plugins or domething has to be done in core of osmand?
Where could I find some docs how to prepare plugins?

I recommend to ask this about Osmand in the Osmand googlegroup mailinglist:!forum/osmand
