Running an app in the background is simple: https://www.b4x.com/android/forum/t...-the-system-tray-notifications.37534/#content

However it will not be able to intercept key events sent to other apps.

Pure Java doesn't support this feature. You might be able to use native libraries for each platform that implement this.
