Android provides a Configuration class that describes all hardware Configuration information related to resources that can be acquired by applications. Contains user-specified information items (local and zoom ratio) and dynamic hardware configurations (a series of input devices ). The Configuration class contains many types of information, such as the system font size, orientation, and input device type. In android development, sometimes we need to adjust the application according to the system settings.
