Abstract

The invention provides a method and a device for prompting printer statuses based on Android. The method and the device are used for an App to refresh printer status information in real time. The technical scheme of the method and the device is as follows: Uevent events based on printing equipment plugging and pulling out are monitored at an application framework layer; when an expected Uevent event is monitored, the status information of the printing equipment is obtained; a first broadcast containing the status information is sent to an application layer by virtue of the build-in broadcasting mechanism of Android; an App registered for the first broadcast obtains the status information. Due to the implementation of the technical scheme, the App is enabled to obtain the status information of the printing equipment in real time when the printing equipment is connected or pulled out.

Description

technical field [0001] The invention relates to the technical field of the Android system, in particular to an Android-based printer status prompt method and device. Background technique [0002] Android Android is a Linux-based open source mobile operating system, mainly used for mobile devices, which is under the continuous leadership and development of the Open Handset Alliance (OHA, Open Handset Alliance) established by Google Google. The Android system is widely customized as an operating system for various devices due to its open source features, including medical devices such as ultrasonic diagnostic instruments. In addition, different from general-purpose Android devices, Android-customized devices generally only run the operating App (Application, application program) used to control the device at the application layer, and the UI (User Interface) of the operating App will completely occupy the display interface. [0003] The Android system can also support customi...
