Google posted a guide on its Android Developers website on Monday that should help developers prepare Honeycomb applications for the new Android 4.0 (Ice Cream Sandwich) operating system, which will run on smartphones as well as tablets. That means Honeycomb developers will need to make their applications compatible with displays smaller than those found on various Android tablets. Creating an Ice Cream Sandwich compatible version of an application is important to reaching a larger audience, too. “Optimizing for handsets can be tricky if your designs currently use all of a large screen to deliver content,” Google explained in a blog post. “It’s worth the effort, though, because Ice Cream Sandwich brings the Honeycomb APIs to handsets and you’ll significantly increase the user-base for your app.” Read on for a link to to the Android developer site, where you can read an in-depth guide to adding smartphone support to Honeycomb apps.
