问题 I have been working on a Android project, that is intended to be compatible with both the Android phones and tablets. On the tablet the app is working great and looks good too. However, on the phone we have been running into issues both programmatically and layout wise (working with a 10.1 inch screen is a lot easier than a 4 inch screen). To solve some of these problems we have decided to deactivate screen orientation but only for the phone version, atleast temporarily. The question is

问题 I'm developing an Android application targeting 2.x and 3.0 devices and thus I'm using the compatibilty API. I'm testing on Android 2.0.

问题 What is the best way to detect a device's orientation in an application extension?

问题 I've built a responsive site using Twitter Bootstrap here: http://zarin.me/cce/ The responsive design works great on iPad and iPhone, however when I flip the device from portrait to landscape, the site is zoomed in instead of adapting to the screen (pinching the screen works). What am I missing? Is this a viewport issue?
