In one embodiment, as shown in FIG. 2, a partial architecture diagram of an Android audio system is provided. The architecture system of the Android audio system includes a kernel space layer 210, a local layer 220, a framework layer 230, and a client layer 240.

The Kernel space layer 210 may include an Audio driver module 211, where the Audio driver module interacts with the hardware and implements the local layer interface for the upper layer to call normally. Here, ALSA, OSS, and a custom audio driver can be selected. The local layer 220 includes an AtlasService_Jni module 221, an AtlasService Interface module 223, and an AtlasService module 225. The framework layer 230 includes an AtlasManager module 231 and an AtlasService module 233.

Among them, the audio information includes playback information, recording information, audio mode setting information, and so on. Because the AtlasService module is set up in the system-level framework layer, it can facilitate interaction with other system services, and at the same time, there is no need to worry about permissions during system calls. Through the above-mentioned architecture, the call control method in each embodiment of the present application can be implemented.

In one embodiment, as shown in FIG. 3, a call control method is provided. The call control method is applied to an electronic device having multiple audio transmission channels. In one embodiment, the electronic device may include a mobile phone, a tablet computer, a laptop computer, a palmtop computer, a mobile Internet device (Mobile Internet Device (MID), a wearable device (such as a smart watch, smart bracelet, pedometer, etc.) Or other electronic devices with voice call function and speakers.

The audio transmission channel includes an earpiece channel, a speaker channel, and a headphone channel; it may also include a microphone channel. In the embodiment of the present application, the word audio transmission channel may be an earphone channel, a speaker channel, and a headphone channel, where the headphone channel may include a wired headphone channel And Bluetooth headset channel. When the audio transmission channel is the earpiece channel, the call voice is issued by the earpiece; when the audio transmission channel is the speaker channel, the call voice is issued by the external speaker; when the audio transmission channel is the earphone channel, the call voice can be through a wired headset or a Bluetooth headset issue.

As shown in FIG. 3, in one embodiment, the call control method includes steps 302-306.

Step 302: Obtain the first audio transmission channel where the electronic device is in a call state.

When the electronic device is in a call state, it can acquire the first audio transmission channel occupied by the current call state. For example, based on the Android operating system built in the electronic device, a new Java class can be created to monitor whether the electronic device is in a call state. Specifically, it can be monitored through the overload of BroadcastReceiver.

When the electronic device is in a call state, the electronic device can obtain the first audio transmission channel in the current call state. Among them, the first audio transmission channel includes an earphone channel, a speaker channel, a wired headset channel, and a Bluetooth headset channel. If the first audio transmission channel is a receiver channel, it means that the voice of the electronic device is output from the receiver; if the first audio transmission channel is a speaker channel, it indicates that the voice of the electronic device is output from the speaker; if the first audio transmission channel When it is the earphone channel, it means that the voice of the electronic device is output from the earphone. For example, based on the Android operating system built in the electronic device, the system function AudioModeProvider.getAudioMode () can be called to obtain the first audio transmission channel occupied by the current call state.

Step 304: Monitor whether the target application generates an operation for setting the second audio transmission channel in the call state.

When the electronic device is in the call state, it can also detect in real time whether the target application generates an operation for setting the second audio transmission channel in the call state. The target application program may be understood as an application program capable of outputting and / or outputting audio signals, and the number of target application programs may be 1, 2, 3 or more. For example, the target application may include applications such as instant messaging, audio playback, video playback, sound control, and voice input.

In one embodiment, the electronic device may preset to construct a list or database including all target applications, for storing identification information of the target applications, and the like.

In one embodiment, the electronic device can monitor the audio behavior of the target application through the built-in monitoring function. The audio behavior includes playback behavior, recording behavior, and audio mode settings. The audio mode setting may be understood as an operation for setting the second audio transmission channel. Taking an electronic device with an Android operating system as an example, a system-level monitoring module can be created at the system framework layer (native / framework layer), and the audio behavior of the target application program can be monitored through the monitoring module. For example, you can set up a listener module in the framework layer and run it in the system service program (system_server). Since the listener module is established in the system-level service framework layer, you can easily interact with other system services without worrying about system calls. Permissions issue.

Optionally, the electronic device can also create an independent monitoring process, set up and call a separate monitoring function in the process, which can be set to start automatically after power-on, and monitor the audio mode setting behavior of any other target application in real time.

Step 306: When the target application runs in the background and generates an operation, the target application is prohibited from opening the second audio transmission channel to maintain the first audio transmission channel for calling.

In one embodiment, the electronic device may obtain the running state of the target application, and the running state may include foreground operation or background operation. For example, the electronic device can monitor the process information of the target application program and determine the running state of the target application program according to the process information. The electronic device can also monitor whether the target application is running in the background based on the use of ActivityLifecycleCallbacks. According to the life cycle of the Activity, onStart () indicates that an Activity is in the foreground and onStop () indicates that the Activity is not visible in the background. Of course, the electronic device can also obtain the running state of the target application through getRunningTasks, and can also obtain the running state of the target application through the combination of getRunningTasks and RunningAppProcessInfo. Here, there is no further limitation on how the electronic device obtains the running state of the target application program, nor is it limited to the above example.

When the electronic device monitors that the target application is currently running in the background and the target application generates an operation for setting the second audio transmission channel, the electronic device may prohibit the target application from turning on the second audio transmission channel to Maintain the first audio transmission channel to talk. That is, although the target application sets the second audio transmission channel in the background, the setting action will not be performed, that is, the target application will not turn on the second audio output transmission channel to maintain the current call status of the first An audio transmission channel. Wherein, the second audio transmission channel may also include a receiver channel, a speaker channel, a wired headset channel and a Bluetooth headset channel. The first audio transmission channel is different from the second audio transmission channel.

For example, when the first audio transmission channel in the call state is a receiver channel, and the target application is running in the background, and a second audio transmission channel is set, wherein the second audio transmission channel is a speaker channel or a headphone channel, that is, the target The purpose of the application setting the second audio transmission channel is to call the speaker channel or the headphone channel. If the target application opens the second audio transmission channel, the call voice of its electronic device is output from the speaker or headset channel. The electronic device can prevent the target application from opening the second audio transmission channel to maintain the first audio transmission channel for the call, that is, the current call voice is still output through the first audio transmission channel, which can avoid audio output during the call Channel changes occur.

The above call control method can obtain the first audio transmission channel where the electronic device is in a call state; monitor whether the target application generates an operation for setting a second audio transmission channel in the call state; when the target application When running in the background and generating the operation, prohibit the target application from opening the second audio transmission channel to maintain the first audio transmission channel for the call to maintain the current call voice or the first audio transmission channel, The situation that the audio output channel is changed during a call can be avoided, and the user experience can be improved.

As shown in FIG. 4, in one embodiment, the call control method includes steps 402-410. among them,

Step 402: Obtain the first audio transmission channel where the electronic device is in a call state.

Step 404: Monitor whether the target application program calls the preset interface function in the call state.

The electronic device may monitor whether the target application program calls the preset interface function in the call state, where the preset interface function is used to set a second audio transmission channel for transmitting audio. When any target application can call the preset interface function, when the function of the preset interface function is valid, the target application can open the second audio transmission channel, and when the function of the preset interface function is invalid, then The target application can call but does not turn on the second audio transmission channel. Specifically, the electronic device can determine the validity or invalidity of the preset interface function by setting the preset interface function.

Further, the preset interface functions include at least the setSpeakerphoneOn () interface function, setMode (AudioManager.MODE_IN_CALL) interface function, isWiredHeadsetOn () interface function or other interface functions for setting the earphone channel and the headphone channel, etc.

For example, in an electronic device based on the Android operating system, the electronic device can set the speaker channel by calling the interface function setSpeakerphoneOn () in the AudioManager, that is, the speaker channel can be turned on or off. The electronic device can set the earpiece channel by calling the function setMode (AudioManager.MODE_IN_CALL) in AudioManager or the construction parameter streamType (STREAM_VOICE_CALL); the electronic device can set and detect the earpiece channel by calling the function isWiredHeadsetOn () in AudioManager.

The preset interface functions are not limited to the above examples, and different forms of preset interface functions can also be set according to actual needs.

Further, the electronic device can monitor whether the target application program calls the preset interface function to apply to the audio device state manager to use the audio transmission channel. If an application is sent to the audio device status manager, it indicates that the target application program has called a preset interface function, that is, the target application program has generated an operation for setting a second audio transmission channel.

Step 406: Determine whether the target application is running in the background.

In one embodiment, the electronic device can obtain the running state of the target application, and the running state can include foreground running or background running, and then can determine whether the target application is running in the background. Specifically, the electronic device can monitor the process information of the target application program and determine the running state of the target application program according to the process information. For example, the electronic device may obtain the running process information of the target application based on ActivityManager.RunningAppProcessInfo. Among them, the process information includes constant type information and variable type information, and according to the acquired process information, it can be determined whether the target application program is running in the background.

Optionally, the electronic device can also monitor whether the target application is running in the background based on ActivityLifecycleCallbacks. According to the life cycle of the Activity, onStart () indicates that an Activity is in the foreground, and onStop () indicates that the Activity is not visible in the background.

Optionally, the electronic device can also obtain the running state of the target application through getRunningTasks, and can also obtain the running state of the target application through a combination of getRunningTasks and RunningAppProcessInfo.

Here, there is no further limitation on how the electronic device obtains the running state of the target application program, nor is it limited to the above example.

Step 408: When the target application is running in the background and generating an operation, the target application is allowed to call the preset interface function, and the function of the preset interface function is disabled, so as to maintain the first audio transmission channel for calling.

In one embodiment, if the target application program generates an operation for setting the second audio transmission channel while running in the background, it allows the target application program to call the preset interface function, and the function of the preset interface function is invalid, To maintain the first audio transmission channel for talking.

In one embodiment, when the first audio channel in the call state is the earpiece channel, the target application is allowed to call the second preset function, and the second preset function is disabled to maintain the earphone channel for the call, where the second The preset function is used to set the speaker channel, or, the second preset function is also used to set the headphone channel. For example, when the call voice is output from the earphone channel, and the target application running in the background calls the preset function function for setting the speaker channel or the headphone channel, the electronic device may be that the function of the preset interface function is invalid, still Maintain the output of the receiver channel of the current call voice, so that the call voice can be output from the receiver channel, and avoid changing the output channel of the call voice.

In one embodiment, when the first audio channel is a speaker channel, the target application is allowed to call the second preset function, and the function of the second preset function is disabled to maintain the speaker channel for calling; wherein, the second preset function It is used to set the earpiece channel and also used to set the earphone channel. For example, when the call voice is output from the speaker channel, when the target application running in the background calls the preset function function for setting the earphone channel or the headphone channel, the electronic device may be that the function of the preset interface function is invalid and still Maintain the speaker channel output of the current call voice, so that the call voice can be output from the speaker channel, and avoid changing the output channel of the call voice.

When the first audio channel is a headphone channel, the target application is allowed to call the second preset function, and the function of the second preset function is disabled to maintain the earphone channel for calling, wherein the second preset function is used to set the earphone channel, It is also used to set up speaker channels. For example, when the call voice is output from the earphone channel, and the target application running in the background calls the preset function function for setting the earphone channel or the speaker channel, the electronic device may be that the function of the preset interface function is invalid, and still Maintain the current channel output of the voice of the call, so that the voice of the call can be output from the headset channel, and avoid changing the output channel of the voice of the call.

In the call control method in this embodiment, during the call, although the target application running in the background can call the preset interface function for setting the second audio transmission channel, it can control the function of the called preset interface function Disabled to maintain the first audio transmission channel of the current call voice, can make the state of the first audio transmission channel and related parameters normal, thereby avoiding the situation of changing the output channel of the call voice, and improving the user's experience during the call.

As shown in FIG. 5, in one embodiment, the call control method includes steps 502-506:

Step 502: Obtain the first audio transmission channel where the terminal is in a call state.

Step 504: Monitor whether the target application generates an operation for setting the second audio transmission channel in the call state.

The above step 502 and step 504 correspond to step 302 and step 304 in the foregoing embodiment one by one, and will not be repeated here.

Step 506: When the target application runs in the foreground and the set second transmission channel meets the preset condition, the target application is allowed to enable the second audio transmission channel, so that the target application performs audio transmission through the second audio transmission channel.

The electronic device can monitor whether the target application is running in the foreground based on ActivityLifecycleCallbacks. At the same time, the electronic device can monitor whether the target application running in the foreground calls the preset interface function in the call state, where the preset interface function is used to set a second audio transmission channel for transmitting audio. When the target application running in the foreground calls the preset interface function during the call state, that is, when the target application generates an operation for setting the second audio transmission channel while running in the foreground, the set second transmission channel can be judged Whether it meets the preset conditions.

In one embodiment, the preset condition includes that the second audio transmission channel is inconsistent with the first audio transmission channel. That is, when the target application is running in the foreground and the set second transmission channel is inconsistent with the first audio transmission channel, the target application is allowed to enable the second audio transmission channel to enable the target application to perform audio through the second audio transmission channel transmission.

For example, when the first audio channel in the call state is the earpiece channel, the second transmission channel set by the target application running in the foreground is the speaker channel. At this time, if the target application needs to play an audio signal, the target application is allowed to enable the speaker Channel to enable the target application to transmit audio through the speaker channel.

Further, when there is no call voice input of the first audio transmission channel, the target application is allowed to play the voice to be played by the target application when the speaker channel is enabled.

In one embodiment, the preset condition includes that the second audio transmission channel is consistent with the first audio transmission channel and that the usage priority of the target application is higher than the usage priority of the call. That is, when the target application is running in the foreground and the set second transmission channel is consistent with the first audio transmission channel and the use priority of the target application is higher than the use priority of the call, the target application is allowed to enable the second audio transmission Channel, so that the target application performs audio transmission through the second audio transmission channel. Among them, the use priority can be understood as the priority level that can be used when both the call and the target application need to use the same audio transmission channel.

Specifically, when the usage priority of the target application is higher than the usage priority of the call, the usage priority is the priority when using the receiver channel. That is, when the target application and the call use the receiver channel at the same time, under certain circumstances, when the use priority of the target application is higher than the use priority of the call, the target application can be allowed to use the receiver channel first, so that The target application transmits audio through the earpiece channel. For example, when the target application is an instant messaging application, and the contact A currently in communication in the target application is more important than the current call contact B, the target application can be considered to have a high priority Use priority for calls.

As shown in FIG. 6, in one embodiment, allowing the target application to enable the second audio transmission channel to enable the target application to perform audio transmission through the second audio transmission channel includes steps 602-604. among them,

Step 602: Detect the idle time period of the call state.

In one embodiment, the electronic device may detect the idle period of the call state during the call state. Among them, the time period during which no input or output voice signal is detected within a preset time period is referred to as an idle time period. Optionally, if the time period in which the input and output voice signals exceed the vocal range within a preset time period is called an idle time period. Among them, the vocal range can be understood as the frequency range of sound waves is 20HZ-20KHZ, where the voice range of human speech only occupies a narrow part of the sound range that humans can hear, generally within 100HZ-8KHZ, and 200- 4000HZ is called the fundamental frequency of human voice, and the frequency of most people speaking is within this range. When the frequency of the input and output voice signals is not within the range of human voice, the time period is considered as an idle time period.

Step 604: Allow the target application to enable the second audio transmission channel during the idle period, so that the target application can perform audio transmission through the second audio transmission channel.

The electronic device can allow the target application to enable the second audio transmission channel during the idle time period, so that the target application can perform audio transmission through the second audio transmission channel. That is, the first audio transmission channel of the communication state of the electronic device will not change, and at the same time, the target application is allowed to enable the second audio transmission channel during the idle time period, so that the target application performs audio transmission through the second audio transmission channel. After the target application completes the audio transmission through the second audio transmission channel, the first audio transmission channel can be used to restore the current call state, and the first audio transmission channel state and related parameters will not be changed, which improves the user's call process. Experience and flexibility in using the target application.

It should be understood that although the steps in the flowcharts of FIGS. 3-6 are displayed in order according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless clearly stated in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least some of the steps in FIGS. 3-6 may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but may be executed at different times. These sub-steps or stages The execution order of is not necessarily sequential, but may be executed in turn or alternately with at least a part of other steps or sub-steps or stages of other steps.
