Okay, I think I know the answer as to what can cause an activity not to rotate.
Every activity I wanted to rotate was started with startActivityForResult() (i.e. it was a sub-activity). It appears sub-activities "inherit" the "android:screenOrientation" of their parent in the manifest. In my case, I have portrait main screens, launching landscape sub-activities that contain forms for keyboard entry. If I set android:screenOrientation="portrait" on the main screen, the sub-activities will not rotate, unless I _explicitly_ add android:screenOrientation="landscape" to them. Which is fine, except they start out rotated, which is not necessarily what a user expects. I suppose I could launch my data entry screens as first-class activities (using startActivity() instead of startActivityForResult()) and pass the results back out-of-band and manually restart the parent, but it sure isn't as pretty as using the built-in result machinery. (Or, yes, I could become more "one" with Android and do two sets of layouts and put the user in absolute control, but that's a lot of work and I am so very lazy...) -- Ward ==================== Hello All: I asked this before and did not get an answer, so let me try again, simpler: On the G1... What can cause an activity to NOT rotate to landscape when the phone is opened? (I want it to rotate.) No android:screenOrientation is set, and the activity is destroyed and recreated, but the new layout is still portrait.
