Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] As known to those skilled in the art, the Android system includes a kernel layer, a HAL layer, a framework layer and an application layer. Wherein, the kernel layer is a device driver layer based on Linux, which is used to load the driver of the device. The HAL layer is an adaptation layer added by Goolge (Google) when some manufacturers do not want to open the source code. It can provide device drivers in a closed-source manner. The purpose is to provide an interface between the framework layer and the kernel layer. The framework layer is used to call the driver of the kernel layer through the HAL layer, and further provide API (Application Programming Interface, application programming interface) to the application layer to realize the operation of the device.

Abstract

The invention discloses a device loading method and device on the basis of Android. The device loading method includes steps of loading device drives of devices to be loaded, mapping device information of the devices to be loaded and generating mapping information; acquiring device identifications of the devices to be loaded according to the mapping information; judging whether an HAL (hardware abstraction layer) dynamic link library matched with the device identifications of the devices to be loaded exists or not according to the index information, if yes, loading the matched HAL dynamic link library, and if not, loading a default HAL dynamic link library, wherein the index information is used for indicting corresponding relation of the device identifications of at least two different specifications of the devices of the same kind and the HAL dynamic link library. According to the above technical scheme, the same-kind devices of different specifications can be intelligently identified in the Android system, corresponding device drives and HAL dynamic link libraries can be dynamically loaded, and the devices can operate normally.

Description

technical field [0001] The invention relates to the field of embedded operating systems, in particular to a device loading method and device based on an Android system. Background technique [0002] The device loading method based on the Android (Android) system means that after the Android system is powered on, the device needs to be loaded correctly, that is, the driver of the device and the HAL (Hardware Abstraction Layer, hardware abstraction layer) dynamic link library are correctly loaded before the electronic product can be used. All kinds of equipment are in normal use. Wherein, the electronic product is, for example, a tablet computer, a mobile phone, etc., and the equipment is, for example, a display screen, a speaker, a camera or a sensor, and the like. [0003] In the existing device loading method based on the Android system, the same type of device can only load one driver and the corresponding HAL dynamic link library, that is to say, the Android system only ...
