Is there any event or listener which fires @ time of orientation changed?
or, how to find out that the orientation of phone is changed?
Thank You

When you rotate your device and the screen changes orientation, Android usually destroys your application's existing Activities and Fragments and recreates them. Android does this so that your application can reload resources based on the new configuration.
First onPause(), onStop() and onDestroy() will be called simultaneously and after some time when the activity restarts the onCreate(), onStart() and onReume() methods will be called simultaneously. So when you change the orientation of a screen the Activity will be restarted.
If you want the activity to not restart during screen orientation change, you can use the below AndroidManifest. xml. Please note the activity android:configChanges=”orientation|screenSize” attribute. This attribute makes the activity not restart when change screen orientation.
On the main screen of Rotation Manager, select an orientation by tapping on either the vertical or horizontal icons next to a specific app to lock it into either landscape or portrait mode. Highlighting both icons will allow that particular app to auto-rotate.
You need to read up on Handling Runtime Changes.
It explains the old way of doing handling stuff like orientation change.
Since Fragments was introduced, they have implemented a new way of doing it (similar to the old one) - but if you don't use Fragments it makes no sense using it.

As far as I know there is a listener for this,
Check out http://developer.android.com/reference/android/view/OrientationListener.html
That is the class have a look through there.
Hope that helped.

You can use OrientationEventListener class instead !! http://developer.android.com/reference/android/view/OrientationEventListener.html

If you are more interested in when an orientation change triggers a redisplay of the layout, you might want to check out this: http://developer.android.com/reference/android/view/View.OnLayoutChangeListener.html
"Interface definition for a callback to be invoked when the layout bounds of a view changes due to layout processing."
