I need a seasoned Android developer who can build a lightweight security layer that makes a thief’s life difficult and keeps my phone online and traceable at all times. The core flow is straightforward: • When someone tries to power the device down, an alphanumeric password prompt must appear before shutdown can proceed. • The moment Wi-Fi drops, mobile data should switch on automatically so the device never leaves the network. and an alphanumeric password prompt must appear to turn off mobile data. • Location must remain visible inside Google’s native Find My Device service, so I can track the phone in real time if it is lost or stolen. I expect an APK plus full source code written in Kotlin or Java, ready to compile in the latest stable Android Studio. You are free to rely on Device Admin, Accessibility Service, or any other approved system-level privileges that achieve these goals without rooting the phone and while keeping battery impact minimal. Please outline your proposed approach, the Android versions you can support, and any permissions the user will need to grant on first run. If you have shipped similar anti-theft, kiosk, or device-management features before, that experience will be a huge plus.
