RIM supports Android developer's.
Here comes the Android port-a-thon | CrackBerry.com
I see that people either seem to love or hate the Android app environment on BB10. I have always believed that it was mid term/time solution. Needed to ensure enough app during the begining. After the power of the developer tools was discovered native would take over. But that will take time. A smart intermediate solution I believe.
But anyway I'm glad to see RIM support the competitions developers. I look forward to them being our developers as well. Has anyone seen this advertised on Android Central or any other Android Site?
