Update – Nov 26, we have added a video to the tutorial page.
With the recent release of MyEclipse 201, it is now possible to use MyEclipse to build apps for MobiOne projects. We have documented a process that uses a combination of MyEclipse and the PhoneGap Build service for building iOS and Android apps. This process will enable the use of additional PhoneGap plugins in your apps and serves as a alternative to the MobiOne App Center Builder services. There are a couple known issues with the video and audio widgets that we are working on and hope to have resolved shortly. We will also be including a video of the process shortly as well.
