RIM has really gone across the board with their updates to the BlackBerry 10 development toolset today. We told you about the native and WebWorks SDK beta updates but now we also have updates to the Adobe AIR SDK and the Android Runtime. The new Adobe AIR SDK beta 2 now also has support for the new Invoke Framework added in the other SDKs. RIM details how to use it in ActionScript here.
Also of note is the updated Android Runtime for BlackBerry 10 Beta. I was hoping RIM would add Ice Cream Sandwich support but that was really shooting for the moon. They have rounded out the new enhancements they introduced in the 2.1 runtime while adding support for the telephony API. That means developers have access to cell location and networking services. Check out all the new API support in the documentation or download the updated v1.2 beta of the BlackBerry Eclipse Plug-in for Android Development Tools and Command Line Tools.
NOTE: The current Dev Alpha simulator does not support the invocation framework thought the actual dev alpha devices do but hopefully that will change soon
