In contrast with the fine grained control camera2's API offered, CameraX (which uses the Camera2 API under the hood) aims to strike a balance between abstracting away the difficult bits of managing the camera while allowing flexibility . Use cases have a configurable aspect ratio to allow the application to specify In the same folder as activity_main.xml, create a new file named activity_camera.xml. The final MeteringPoint is ignored by CameraX. The ListenableFuture returned by both APIs offers the option for applications to be notified when a repeating request with the specified zoom value is completed. A great way to make our camera app more interesting is using the ImageAnalysis feature. Android CameraX API also provide utility functions to handle all life-cycle events. Crop the live stream from the Camera X to fit the bounding box overlay. Does anyone have a sample, preferable in Java, but anything is fine or idea if this is the correct approach.
