It's been a few weeks since Chapter 8 of Palm webOS Rough Cuts was released, and now Chapter 10, Background Applications, is out to read up on before the Mojo SDK hits by summer's end. And no, they didn't skip a chapter, rather added a new one (Chapter 7, "Advanced Styles") Below is the summary of what to expect from the latest chapter:
"Whether you're interested in building an advanced application or just want to add notifications to a basic application, this chapter covered some essential topics. There was a broad review of advanced multi-stage applications with an introduction to Notifications and Dashboards. You learned that advanced applications are based on an Application assistant, which can handle external launch requests and potentially run in the background. You were also shown how to customize your application's behavior when minimized, meaning switched out of the foreground view, and how to use the internal application notification chain to coordinate actions between assistants or share events and data.
With the techniques learned in this chapter you should be able to move your application to the background, build a dashboard-only application or use secondary card stages to support separate activities."
