[android-developers] How to force Activity in landscape mode without Activity restart
Hi folks, I have a problem to start/create Activity in landscape mode. My Activity need to start in landscape mode and be used in landscape mode by users. So far, I used setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) to force screen orientation of my Activity to landscape mode in onCreate() method. In addition to this screen mode requirement, my application need to start another background thread in onResume() method, and this thread takes some seconds in order to finish an initialization process, and it is not desirable to to stop/restart this thread's service during the initialization process. However setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) forces my Activity restart in a very little while (means onCreate-onResume-onPause-onStop are executed twice at the first place). As a result, my background thread be stopped/restarted during the initialization process, and this makes me a mess at this moment. If anyone has any idea, please share and discuss here. Thank you. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

This is a great work. Thank you, Stefano. Just one question. I'm wondering if this API is not thread-safe. Is this assumption correct?

[android-developers] Re: What SensorManager.getOrientation returns?
To make getRotationMatrix work, just pass the accelerometer and magnetic field sensor's observed values array to gravity and geomagnetic parameters and memory-allocated 4x4 float array to R and I parameters. I tried to pass 3x3 arrays as api doc say, but it didn't work. Y.T.

[android-developers] Re: What SensorManager.getOrientation returns?
Thank you for replying, Serge. I have known exactly what api document says about this method. But after some times of trial to figure out what it means, finally I realized values[] is in radian and this is everything what I needed to know...

When it returns, the array values is filled with the result: values[0]: azimuth, rotation around the Z axis. values[1]: pitch, rotation around the X axis. values[2]: roll, rotation around the Y axis.

The preference framework will refresh the UI when a preference has a
UI-visible attribute changed, for example the summary. So, you can just do
myPreference.setSummary(myPreference.getValue()) (assuming you want to show
