include android:configChanges="orientation" in your AndroidManifest.xml to the activity displaying window. Doing this tells android that you are going to handle orientation change yourself and eventually it will not destroy your activity and keeping the window displayed.

This technique is good if you dont have different layouts for portrait and landscape mode. However, if you do, you may still perform custom layout implementation by detecting the orientation mode as below:

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    if(newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE)
        Log.i("orientation", "Orientation changed to: Landscape");
    else
        Log.i("orientation", "Orientation changed to: Portrait");
}

for preview, download and install this sample app.
