How to Install Xposed Framework for Android Oreo 8.0/8.1 On any Android device
У вашего броузера проблема в совместимости с HTML5
The installation process is simple, as always. All you have to do is install the Xposed Installer that is attached to rovo89’s forum thread. You will also need to flash the latest framework zip onto your device. The framework zip can be installed by flashing it through a custom recovery such as TWRP. Users running Android 8.0 Oreo will need to install the SDK 26 framework, while users running Android 8.1 will need the SDK 27 framework. The source code for the updated framework will be published once it’s cleaned up and Xposed for Oreo leaves its beta stage
