I don’t have any problems like yours on Android 9. Try usb debugging to see what’s happening.
You may try to register empty function on back button event.

Hi, do you have resolved this issue? because we have wrote this:

cc.systemEvent.on(cc.SystemEvent.EventType.KEY_UP, this.onKeyUp, this);
…
onKeyUp(event) {

    var script = this;

    if(cc.BACKBUTTONID.currentID[0] !== script.ID)
        return;

    if (event.keyCode === cc.macro.KEY.back) {

        // the back button of Android Device is pressed
        // maybe it's not work in Web environment
        this.emit();
    }
    else if (event.keyCode === cc.macro.KEY.backspace) {

        // the backspace of PC/Mac is pressed
        this.emit();
    }
    else if (event.keyCode === cc.macro.KEY.escape) {

        // the escape of PC/Mac is pressed
        this.emit();
    }        
},

If you use api 28 or higher then add this this.getGLSurfaceView().requestFocus(); to onCreate in AppActivity.java
