If you'd like a quick tour of all the options for setRequestedOrientation(), my app, SmartVolume Free, does this, and lets you control what value to supply to setRequestedOrientation() in a preference setting. (The default is to not set it at all, and use the system's setting).
Of course, it's not hard to throw the code into your app, but this way you can switch back and forth more quickly. I'm still not clear on how the orientation is chosen for ActivvityInfo.SCREEN_ORIENTATION_NOSENSOR. On my device (N1) it seems to always come up in Portrait. I don't know if this is intended to be "a suitable default for the device", or something else. It doesn't appear to be "what orientation the device was in on start", which I think would be more useful. I guess I'll go fill a documentation bug. I put this in for a couple reasons. One is that my app is more usable in portrait mode, but switching to portrait mode if you're using it in landscape may not be desirable. Another is that before 2.1 update 1, the launcher would crash (out of memory) if it was behind a window that switched to landscape and you had too many apps...
