Android Employee Activity Keylogger

I need a discreet Android application that records employee device activity for compliance purposes. The app must log every keystroke, track websites visited in any browser, and chronicle foreground app usage with accurate timestamps. At user-defined intervals these three data streams should be consolidated into a clear report and sent automatically to a chosen email address. The service has to survive reboots, remain hidden from casual discovery, and run smoothly on Android 9 through 14 without demanding root access. Battery and data consumption should be minimal. A single first-run screen where I can enter SMTP credentials, reporting frequency, and perhaps an optional keyword filter is sufficient—after that, the interface can vanish. Deliverables • Release-ready APK plus fully commented source code • Straightforward setup guide suitable for a non-technical manager • README detailing the permissions used and collection methods Acceptance criteria • Keystroke, website, and app-usage logs arrive via email on schedule with correct timestamps • No visible notifications or icons after initial configuration • Service restarts automatically after a reboot or update
