Hi guys,
I need to create small desktop application which will show the users some direction between two points on map. User need to input first adress and second adress and I will show him the road from start to end point.
I found API for this on OpenRoute or OpenStreet Map (okey, basicaly I can use google maps but is not free)... In any case - I can get info from Api with next code:
I recived this response - In Json:
And what now?
How can I use result to show user the location (or direction)?! It's posible to show map inside of desktop B4J app with WebView?
And how?
I can not find any example... Sorry, maybe it's stupid question, I'm new in world of B4J with web api... Any suggestion how to move forward will more as usefull...
Tnx, Darko
