We need to set the orientation of our app to reverse landscape. Unfortunately, this is only supported in api 9+, so as suggested by a Google engineer below, we need to set the orientation programmatically based on android.os.Build.
1) We've tried doing this in onCreate, but it prevents the activity transitions from showing. Is there a way to set the orientation programmatically so that the transitions are still shown? 2) Is there someway of having a conditional in the manifest, such that screenOrientation defaults to 'reverseLandscape' if supported, otherwise 'landscape'? 3). It seems reverse landscape can be reached if screenOrientation is set to 'unsepcified' (even less than api level 9), but then portrait orientations are allowed as well. Is there someway to prevent the portrait orientations (in < api level 9 too)?

I assume I would do this in onCreate. If I do do this, there are no animations to a new Activity (the slide in), only animations when ending the new activity. How can I correct this? FYI, I'm testing on a Nexus One with 2.3.6 Thanks S On Wed, Sep 28, 2011 at 12:10 PM, Stefan Alder <twigbra...@gmail.com> wrote: > I found this thread, which seems related, but the result is a blank > screen.
