title: UI Guidelines for Android Honeycomb on Tablets
body: <p>The UI in Android Honeycomb is very different. I'm looking for things that have changed that would be of interest to developers. Google hasn't updated it's UI guidelines yet, so I am trying to find this stuff out by inspecting the layouts. I am mainly interested in dimensions of icons and new types of views.</p>
  
  <p>The action bar height is 56dp (<code>?android:attr/actionBarSize</code>). It seems that the menu icons are 32 x 32 dp now, they were 48 x 48 dp before. Since they are in the action bar, they have a lot of padding around them. The size of a menu icon with padding is 64 x 56 dp. I needed this since I was trying to put a <code>ProgressBar</code> as a menu item.</p>
  
  <p>Anything else change? Also, I'm interested in the size of some common UI patterns, like the widths for a list/detail layout like the mail client.</p>
