Specifically, a Linux system is installed in the intelligent terminal, but an Android application program is installed in the Linux system. The intelligent terminal can be a mobile intelligent terminal, such as a laptop, a tablet, a mobile phone and the like, and can also be a non-mobile intelligent terminal, such as a desktop computer and the like. In the following, the smart terminal is taken as an example of a mobile phone, but it should be noted that the description is only an example and is not intended to limit the scope of the present invention. The other descriptions in the embodiments of the present invention are also for illustration purposes, and are not intended to limit the scope of the present invention.
The embodiment of the invention provides a Linux-compatible Android audio control method applied to a Linux end, wherein the Linux end comprises: the method is applied to the audio service, and the specific implementation of the method is as shown in fig. 1:
Specifically, a service (AudioServer) capable of communicating with the Android terminal is created in advance on the Linux terminal, and the service is communicated with the Android terminal through the AudioServer. And the Audio Server receives the audio control request sent by the Android terminal and obtained through the Socket.
Specifically, before the Linux end and the Android end communicate, the AudioServer obtains hardware parameters of the audio driver through an audio service interface (PulseAudio API), where the hardware parameters include: support recording function, support broadcasting function, not support recording function and not support broadcasting function, etc. The audioservice sets the state of the hardware parameter of the audio driver supporting the recording function and the broadcasting function to be valid, and sets the state of the hardware parameter of the audio driver not supporting the recording function and the broadcasting function to be invalid, and stores the state, which can be specifically shown in fig. 2.
S201, the AudioServer is successfully established.
S202, the audioServer sends a hardware parameter acquisition request to the audio driver.
S203, the audio driver returns the hardware parameters.
And S204, the AudioServer stores and manages the hardware parameters.
The PulseAudio is an Interface library of a third party, and a plurality of Application Programming Interfaces (APIs) are defined in the PulseAudio. The invention transfers the audio control request to the PulseAudio API by calling the PulseAudio API in the interface library, and then calls the audio driver by the PulseAudio API to execute the operation corresponding to the audio control request.
Wherein, the AudioServer operates as a service under a common user in the Linux end.
In a specific embodiment, when the audioserver receives an audio control request sent by an Android terminal, whether a communication connection between the Android terminal and a Linux terminal is established is judged based on a pre-stored state of a hardware parameter of an audio driver, when the state of the hardware parameter of the audio driver is valid, the communication connection between the Android terminal and the Linux terminal is established, and when the state of the hardware parameter of the audio driver is invalid, the communication connection between the Android terminal and the Linux terminal is not established.
And step 102, calling an audio service interface, controlling an audio driver to execute an operation corresponding to the audio control request through the audio service interface, and returning an execution result of the audio driver to an Android terminal through Socket.
In one embodiment, the audio control request carries an audio control type, and therefore, before controlling the audio driver to execute an operation corresponding to the audio control request, the audio control request needs to be parsed to obtain the audio control type corresponding to the audio control request, where the audio control type includes: an audio recording type and an audio playing type. Further, after the audio control type is obtained, the audio driver is controlled to perform an operation corresponding to the audio control type based on the audio control type. The method comprises the following specific steps:
when the audio control type is an audio recording type, calling an audio service interface, and controlling an audio driver to execute an audio recording operation through the audio service interface; and when the audio control type is an audio playing type, calling an audio service interface, and controlling an audio driver to execute audio playing operation through the audio service interface.
In one embodiment, the data returned by the audio driver received by the AudioServer is different for different audio control types. When the audio control type is an audio recording type, receiving audio data returned by an audio driver through an audio service interface, and returning the audio data to the Android terminal through a Socket; and when the audio control type is an audio playing type, receiving a success identifier returned by the audio driver through the audio service interface, and returning the success identifier to the Android terminal through the Socket.
The audio data is in a Pulse Code Modulation (PCM) format, and the PCM audio data is a bare stream of uncompressed audio sample data, which is standard digital audio data converted from analog signals through sampling, quantization and encoding.
Specifically, all the data received by the AudioServer are valid data returned by the audio driver, and of course, the audio driver may also return invalid data, for example, when the audio control type is an audio recording type, and the audio recorded by the audio driver is null, the null audio data is returned to the AudioServer; for another example, when the audio control type is an audio play type, the audio driver returns a failure flag to the AudioServer.
The audio control method, the system and the device are compatible with Android and used for Linux, the method is applied to audio service of a Linux end, and the audio control request sent by the Android end and obtained through Socket is received; and calling an audio service interface, controlling an audio driver to execute the operation corresponding to the audio control request through the audio service interface, and returning the execution result of the audio driver to the Android terminal through the Socket.

Therefore, the HAL layer of the Android side is modified to be able to communicate with the AudioServer of the Linux side.
Specifically, the Android terminal further includes an audio application program, and the audio application program is used for generating an audio control request by operating the audio application program of the Android terminal. For example, the audio application includes a record button and an announcement button, and the user generates the audio control request by clicking the record button or the announcement button.
In a specific embodiment, the audio control request carries an audio control type, the audio control type corresponding to the audio control request generated by triggering the recording button is preset to be an audio recording type, and the audio control type corresponding to the audio control request generated by triggering the broadcasting button is a request type relation table of the audio broadcasting type. Therefore, the audio control type of the audio control request is determined based on the request type relation table; when the audio control type is an audio recording type, generating an audio control request carrying the audio recording type; and when the audio control type is the audio playing type, generating an audio control request carrying the audio playing type.
And step 302, receiving an execution result corresponding to the audio control request, which is returned by the Linux end through the Socket.
