Zoom Api Delay

[Egor Chebotarev]

Good day.

Working with camerax APi .

I often see small problems with scale gesture delay and no smooth camera zoom when using zoomRatio() method from camerax SDK.

It looks like  scale gesture distance between two fingers a bitlarger than normal size...
ZoomRation event starts too late,about 50ms-100ms delay.

Also detect lagging and jumping frames while zoom in/out.

Sometimes it can does not not listen to fast-scale gestures at all.

I suppose problem was on my side. I reassemble application in release mode(it was debug build) and update libraries for last stable version.

Also remove extra code  inside OnTouchEvent function.

Now it works much better.

Hi Egor, 

FYI,  the latest CameraX 1.4.0-alpha04 contains a fix that potentially could cause the jumping frame issue while zooming.
