Excerpt:

In the shared video, a method is demonstrated to detect rotational movements on a touchscreen and accordingly rotate an Android application’s layout between Portrait and Landscape orientations. The code includes handling touch events in such a way that if swiping is detected, the app’s orientation switches. Full source code is provided along with screenshots showcasing the initial layout and the layout after the application has been rotated.
