After I installed Worklight 6.1 and the Android plug-in and SDK, I got the below exception when trying to build an app:
[2013-12-13 13:27:07] Starting build process: application 'WorklightTest', all environments
[2013-12-13 13:27:10] Failed importing native project for 'Android phones and tablets' Failed to read project description file from location D:\Development\worklight_dev\WorklightTestApp\apps\WorklightTest\android\native.project.
[2013-12-13 13:27:10] A core eclipse exception has occurred: Failed to read project description file from location D:\Development\worklight_dev\WorklightTestApp\apps\WorklightTest\android\native.project.
Actually, I did it with worklight 6.0...
