问题 I am trying to check to see whether the android navigation bar is present on load so that I can adjust a layout accordingly, does anyone have any suggestions?

问题 Ice Cream Sandwich (Android 4.0) adds the option of having the Action Bar at the bottom of the screen on phones, and that\'s something I\'d love to have in an application of mine. The docs mention uiOptions=\"splitActionBarWhenNarrow\" for when you want something, i.e. tabs, at the top and Action Bar shortcuts at the bottom. I\'ve tried adding the line in the application manifest, as described in the docs, but haven\'t got it working thus far. Here\'s an example: Also, I noticed that on my

问题 I have a working tablet application which I am now trying to make work on phones too. On a table there is two fragments on the screen a list fragment and a details fragment.
