You need to implement the method
public void onConfigurationChanged(Configuration arg0)
{
super.onConfigurationChanged(arg0);
}
in your activity. and in manifest file, you have to the statement
android:configChanges="keyboardHidden|orientation" for that activity.
so when your screen orientation is changed, it wont call the onCreate
() method again.
