For a while now, the Palm Pre and its webOS have been out and about, but the accompanying App Catalog remained remarkably empty, because Palm had not yet opened its software development kit for everyone. The SKD was leaked
not too long ago, and today Palm has announced the official release of the Mojo SDK
for everyone who wants to get their hands on it. It includes a webOS emulator.
The news was announced on the official Palm weblog. The Mojo Software Development Kit, as it's called, is completely free and open to anyone with a valid email address. It includes documentation and the new Mojo developer forums. You can get the SDK from the newly launched Palm webOSdev site. Palm has high hopes for the Mojo SDK and the webOS App Catalog.
The initial response to Palm webOS apps -- from both developers and customers -- has been enthusiastic. Even in its initial beta stage, over 1.8 million apps have been downloaded from the beta App Catalog since Palm Pre was released less than six weeks ago. Thousands of developers have participated in the Mojo SDK early access program since it began in early April. New applications are in the pipeline for the Palm App Catalog, and the App Catalog submission process will be opened to all developers beginning this fall.
Also of interest are the user interface guidelines for the webOS, which detail how to design the UI (and its behaviour) of your application. Let's hope Palm's submission process isn't a total unpredictable arbitrary mess like Apple's. Happy coding!
