[android-developers] Re: Is it possible to rotate screen by program code but not accelerometer sensor?
You can set the orientation of the app in your manifest using android:screenOrientation on your activity element. That will hard-code it to rotate to landscape or portrait by default, then just use SENSOR_DELAY_UI when creating the handler as I think that's the slowest and uses the least battery. Maybe you can switch between landscape and portrait by modifying the activity since it's exposed in the xml it is probably exposed in the api too.

Re: [android-developers] Re: Is it possible to rotate screen by program code but not accelerometer sensor?
Thank you all for answer. If there is no system level API, may I control top activity from my service? for example, AnyTopActivity.setRequestedOrientation(). 2010/9/20 Doug beafd...@gmail.com On Sep 19, 1:47 am, HaMMeReD adamhamm...@gmail.com wrote: Maybe you can switch between landscape and portrait by modifying the activity since it's exposed in the xml it is probably exposed in the api too.

Re: [android-developers] Re: Is it possible to rotate screen by program code but not accelerometer sensor?
Answer my own above question, it is impossible. Because there is no hotkey mechanism in android. Maybe need to research android source code to find solution. Have anyone any suggestion? 2010/9/20 San Zhang dahua007...@gmail.com Thank you all for answer.

Re: [android-developers] Re: Is it possible to rotate screen by program code but not accelerometer sensor?
There is an Auto rotate system setting, but apparently turning it off forces everything into portrait, at least on my Droid. Seems a little bit weird. -- You received this message because you are subscribed to the Google Groups Android Developers group.
