WiFi Recovery is an Android application that retrieves saved WiFi passwords from the device’s system files. The app requires root access to read the wpa_supplicant.conf file where Android stores network credentials in plain text format.
The application uses libraries including ActionBarSherlock, ZXING for QR code generation, and RootTools for system-level file access. It provides a simple interface to view saved network passwords and can generate QR codes for easy network sharing. The project has been archived as modern Android versions have changed WiFi credential storage mechanisms.
