Laszlo Kishalmi commented on NETBEANS-2638:
-------------------------------------------
I'm having some android SDKs laying around, so instructions are welcome. Though
supporting Android development is not among my goals at the moment. This NPE
could occur in other (hopefully rare) cases as well.
Also I recommend adding a settings.gradle in the root of the sample project
even it is empty.
