I am new to Camera API and building a simple camera app where I have built the basic camera working layout but I am missing clue to incorporate the zoom features I want the app and its codebase as simple as possible , I want to implement swipe up to zoom in and swipe down to zoom out feature.
I have already implemented the basic camera which captures image - what should be added to achieve that desired functionality(swipe to zoom gesture) only ?Thanks in advance.

You can use the MotionEvent class to handle this. Refer this https://stackoverflow.com/questions/18594602/how-to-implement-pinch-zoom-feature-for-camera-preview – abhishek gupta Sep 18 '18 at 09:04

You detect the swipeUp Event using SimpleOnGestureListener and use the zoom functionality accordingly.You can refer this How to detect swipe direction between left/right and up/down
