I did some test with Eclipse.
The first time my test didn't start, infact there was a problem with license (it did found it), so I added the statement ArcGISRuntime.setLicense(...) in the code and after it starts.
Now there is another problem. The test generate an exception
java.net.UnknownHostException: services.arcgisonline.com
because in the default generated test there is a ArcGISTiledMapServiceLayer with an http address for the maps, I suppose.
Eclipse right configured for internet
After this I tried to load a my map package file, but the result is same though the exception is different:
java.net.MalformedURLException: no protocol: null/admin/createService
...
...

Message : Satrtup failed : Invalid license provided
Any idea??
thanks,
Ivano
PS: I have a valid license
