Thanks Alexander. I tried it, and have used it in the past, but it no longer seems to work (Android 8). What I'm looking for though is a way to control the system click sound. When I enable the system click sounds from device settings I do get a nice "click" with each key press. I just want to be able to turn this on or off from within my app. In other words, if system click sounds are turned off, I'd like to be able to turn them on within my app, for use just by my app!
