Android start layout with current orientation, after that disable rotation

I want to make possible to use an activity in landscape / portrait. The activity starts with the layout for the current orientation (that means before starting the activity). After that it has to stick to it, and not react to orientation change.

I tried putting 

android:configChanges="orientation"

in the manifest of the activity, and overriding

@Override
public void onConfigurationChanged(Configuration newConfig) {
// TODO Auto-generated method stub
    super.onConfigurationChanged(newConfig);
}

to do nothing (tried commenting the super call too, but this lead to exception) but this has not the effect disabling the rotation change - the change is processed and the layout reconstructed, it just doesn't use the correct one.

And I can't use

android:screenOrientation

Because it seems I have to specify only one mode for always, and that's not what I need either. And anyways, if I specify something there, the activity gets reconstructed when rotating. Tried with

android:screenOrientation="nosensor"

that doesn't do anything

Here there's a lock of current orientation with code http://www.samcoles.co.uk/mobile/android-lock-and-unlock-screen-orientation/

But it achieves the same effect as specifying orientation in XML (keeps layout but reconstructs the activity). It's a bit nearer to what I want (keeps orientation from start), but reconstructs the activity and I don't want it to react at all.

Add this to onCreate

if (this.getResources().getConfiguration().orientation == ActivityInfo.SCREEN_ORIENTATION_PORTRAIT){
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);}
        else {setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);}

Try

@Override
public void onConfigurationChanged(Configuration newConfig) {
    newConfig.orientation = getResources().getConfiguration().orientation;
    super.onConfigurationChanged(newConfig);
}

android:configChanges="orientation" doesn't work on the emulator at all, but it works fine on devices.
