Is Honeycomb only for tablets?

I know this to some people might sound very stupid question, but is Honeycomb only for tablets? I am making a thesis project developing an Android ap开发者_Go百科p for mobile: which version would you suggest I should use? The one that is most popular, I guess?

Yes. currently only for tablets. However the goal is combining the phone and tablet os on the next release, named Icecream Sandwich. It was also said at Google I/O that there will be a Gingerbread release bringing some features from Honeycomb.

See the chart published by google at http://developer.android.com/resources/dashboard/platform-versions.html. This will give you an idea of which platform to develop for.

Gingerbread 2.3.3 is most popular to develop for right now, it has few new APIs that supported hardware acceleration. And Android Ice Cream Sandwich has backward compatible support for older Android SDK .
