My problem was much simpler :) All I had to do is cancel previously called autofocus. Basically the correct order of actions is this: protected void focusOnTouch(MotionEvent event) { if (camera != null) { camera.cancelAutoFocus(); Rect focusRect = calculateTapArea(event.getX(), event.getY(), 1f); Rect

I'm sure there's some way technically to simply shut off the autofocus, making the camera start up in a default focus and never moving away from that.

You need to check if the device you're running on actually supports manual controls in camera2. The key is whether the available capabilities of the camera device lists MANUAL_SENSOR. If so, then you can control the lens by setting the autofocus mode to OFF, and then setting the lens focus distance to your desired value
Though this answer does not show how to focus in on a single area, it is definitely useful in showing how exactly to focus the camera to begin with. Here is what i have done. This works on my device (Droid DNA by HTC), built in Android Studio. In both OnSurfaceChanged() and OnSurfaceCreated() , I have the following
If so, then you can control the lens by setting the autofocus mode to OFF, and then setting the lens focus distance to your desired value. If MANUAL_SENSOR is not listed, then the device very likely doesn't support manual focus control (Some manufacturers use private interfaces for their default camera app
Another situation where manual focus is used when auto focus just doesn't work, usually because you don't have enough light. And a third common use is "focus trap", you pre-focus on a specific spot, switch to manual focus to avoid the camera changing focus and wait for your subject to arrive at that spot.
