Problems solved by technology

[0005] To sum up, due to the many intermediate layers and processes involved in the operation process of Android application output audio in the Android system, the audio data processing process is more complicated, and the overhead of the data transmission process is relatively large, so the audio output efficiency of Android applications is relatively low. Low, and the output delay is large, which greatly affects the user experience. In the existing Android compatible environment running on the Linux platform, the audio output of the Android application is generally based on the audio output mechanism of the Android system, so the above problems still exist

Embodiment Construction

[0028] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0029] The present invention provides a low-delay audio output method for Android applications on a Linux platform. Different audio players are used to complete the audio output of the Android application.

[0030] The present invention provides a low-latency audio output method for Android applications on a Linux platform, and the process is as follows figure 1 shown, including the following steps:

[0031] Step 1. In the Android-compatible environment of the Linux system, when the Android application needs to output audio, check whether there are other Android applications that are outputting audio in the current Android-compatible environment. If there is no other Android application that is outputting audio in the current Android-compatible environment , then go to step 2; if there are other Android applications that are outputting audio in the cu...

Abstract

The invention discloses a low-latency audio output method for Android applications on a Linux platform. The audio output mode is determined by obtaining the type of audio player used by an Android application in an Android compatible environment in a Linux system, and different output modes can effectively reduce The process involved in the audio playback process of the Android application is reduced, the data interaction between the processes is reduced, the audio output efficiency of the Android application is effectively improved, the output delay is reduced, and the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of development of mobile applications running on desktop operating systems, and particularly relates to a low-delay audio output method for Android applications on a Linux platform. Background technique [0002] Audio data processing is a very important part of the Android system. It is responsible for the collection and output of audio data, the control of audio streams, the management of audio devices, and volume adjustment. It mainly includes the Audio Application Framework and the Audio Native Framework. Framework), Audio Services (Audio Services) and Audio Hardware Abstraction Layer (Audio HAL). In addition, MultiMedia is strongly related to audio data processing. MultiMedia is responsible for the encoding and decoding of audio and video. MultiMedia outputs the decoded data through AudioTrack, and the recording data collected by AudioRecord is handed over to MultiMedia for encoding. [0003] In general...
