I have an app that has an old MapQuest key and I wanted to show a route on the Map. However, it didn't work, and on my Callback I got this message:
This key is not authorized for this service. If you do not have a key, you can obtain a free key by registering at http://developer.mapquest.com.
Does it mean my key is invalid, expired, or maybe I have to pay to have this service?
I visited MapQuest AppKeys page today (Mar 29 2015) and it tells me that:
The ability to create Free & Open AppKeys has been temporarily paused.
Can someone confirm whether routing is allowed with a free key?
You can draw a route on a MapQuest map with a Free&Open Key, but you cannot use their service (I mean use Android SDK for routing) because it's not free.
Although, I've created a demo app that get directions from MapQuest'S Web Service (wich is free) and then uses that response to draw the route. You can also request guidance information.
Take a look at my github repo: https://github.com/sebasira/Android-RouteWebService
Hope it helps you! (it was also a headache for me at the time)
