Handling Orientation Change in Android

If you want perform some operation in the orientation the following snippet useful. If you change the orientation then one default method will call i.e onConfigurationChanged()

@Override
 public void onConfigurationChanged(Configuration newConfig)
{
         super.onConfigurationChanged(newConfig);
         if(newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE)
         {           
                  // indicates orientation changed to landscape
         }             
         else if(newConfig.orientation == Configuration.ORIENTATION_PORTRAIT)
         {           
                  // indicates orientation changed to portrait
         }            
}

Note :
We will change the declaration of the Activity in manifast.xml to the following :
<activity android:name=".YourActivity" android:label="@string/app_name" android:configChanges="orientation|keyboardHidden" />
