I need an end-to-end solution that lets me take full remote control of Android devices from either Windows or macOS. Think of the fluid experience of TeamViewer, but tailored to Android-only targets and with a built-in user, device, and permission manager. Core workflow • An Android app installs on each device, signs in with email-based credentials or display token to be added in the desktop app, and then runs quietly in the background. From there I can launch full desktop-level control sessions or transfer files both ways. • A desktop console for Windows and another for macOS lets me see a live list of every enrolled phone or tablet, its status, assigned user, and permission set. From that same screen I should be able to start a remote session, push or pull files, add or remove devices, and manage user roles. Key functions: 1. Email sign-up or Token Display on Android. 2. Persistent background service so devices stay reachable even after reboots. 3. Smooth screen-sharing and input control with minimal latency. 4. Secure file transfer (both directions, multiple files or whole folders). 5. Central desktop dashboard (Win & macOS) for: • Listing devices and live status • Adding/removing devices and users • Assigning devices to users and granular permission options 6. Encrypted connection and authentication flow comparable to TeamViewer security standards. Deliverables • Android APK with source code. • Windows installer (.exe or .msi) and macOS app bundle (.dmg) with all source codes. • Backend or relay service code (if required) plus database schema. • Brief deployment guide and developer-level documentation. • provide all source codes. If you’ve already handled similar remote frameworks, let me know how you would wire those in so we can save time.
