An android system server, remote desktop audio redirection method and system

Abstract

The invention discloses an audio redirection system based on a remote desktop of an Android system. The system includes: an Android system server and a remote desktop client, wherein the Android system server includes: a music playing application and a recording application of the application layer, and a system The Audio Finger process of the framework layer, the audio hardware abstraction layer module of the hardware abstraction layer and the remote desktop server of the system framework layer; the remote desktop client includes: a second communication module, an audio playback redirection processing module, a recording control message processing module and Recording redirection processing module, the present invention also provides a method for using the system to carry out audio redirection based on the remote desktop of the Android system, which realizes two functions of audio playback redirection and microphone recording redirection, and satisfies the requirements of the audio system in the remote desktop environment. need.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an Android system server, a remote desktop audio redirection method and system. Background technique [0002] Traditional remote desktop technology is mainly based on PC operating systems such as Windows, Linux, and MacOS. However, with the large-scale application of smart mobile devices and the popularization of enterprise mobile office, there are more and more market demands for remote desktops based on mobile operating systems such as the Android system. Compared with the traditional remote desktop, the remote desktop based on the Android system delivers the entire Android desktop to the user, and has the redirection function of audio, camera and other hardware devices. [0003] In the Android system, audio is a very important basic function, so in the Android remote desktop environment, the function of audio redirection is very important to improve the user experience...

Problems solved by technology

However, this solution is applicable to the Ubuntu operating system, but not to the Android operating system. Although the underlying layers of the two operating systems are based on the Linux kernel, the audio frameworks they use are not the same. The PulseAudio used by the Ubuntu system, and the Android The AudioFlinger used by the system, therefore, the audio redirection scheme of the two systems must be different

[0007] In summary, the above solution is not applicable in the remote desktop audio redirection scenario based on the Android system, mainly because the Android system does not provide a system API interface for intercepting system audio playback data and injecting recording and collecting audio data to upper-layer applications. transfer
