在一个实施例中,电子设备可以预设构建包括所有目标应用程序的列表或数据库,用于存储目标应用程序的标识信息等。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.
步骤304,根据音频模式监听目标应用程序用于播放音频数据的音频输出通道是否异常。Step 304: Monitor whether the audio output channel used by the target application to play audio data is abnormal according to the audio mode.
每个音频模式可对应多个用于播放音频数据的音频输出通道,例如,当目标应用程序为通话类应用程序时,该目标应用程序对应的音频模式为通话模式,当电子设备处于通话状态时,可以通过听筒通道、扬声器通道或耳机通道进行语音通话,也即,通话模式对应的音频输出通道包括听筒通道、扬声器通道和耳机通道。Each audio mode can correspond to multiple audio output channels for playing audio data. For example, when the target application is a call application, the audio mode corresponding to the target application is a call mode, when the electronic device is in a call state , You can make a voice call through the receiver channel, speaker channel or headset channel, that is, the audio output channel corresponding to the call mode includes the receiver channel, speaker channel and headset channel.
同时,每种音频模式可设有至少一种默认的音频输出通道。例如,音频模式为通话模式时,其对应的默认音频输出通道可包括听筒通道和耳机通道,当电子终端连接耳机时,其默认音频输出通道为耳机通道,当电子设备未连接耳机时,其默认音频输出通道为听筒通道。例如,音频模式为铃声模式或闹钟模式时,其对应的默认音频输出通道为扬声器模式。At the same time, each audio mode can be provided with at least one default audio output channel. For example, when the audio mode is a call mode, the corresponding default audio output channels may include a receiver channel and a headset channel. When the electronic terminal is connected to the headset, the default audio output channel is the headset channel. When the electronic device is not connected to the headset, the default The audio output channel is the earpiece channel. For example, when the audio mode is the bell mode or the alarm mode, the corresponding default audio output channel is the speaker mode.
当目标应用程序播放音频数据时,电子设备可以监听当前用于播放该音频数据的音频输出通道,若该音频输出通道与该目标应用程序的音频模式对应的默认音频输出通道一致时,则可认为目标应用程序用于播放音频数据的音频输出通道是正常的,反之,则可认为目标应用程序用于播放音频数据的音频输出通道是异常的。例如,电子设备来电时,其铃声从听筒通道发出或其铃声从耳机通道发出,则都可认为用于播放来电铃声的目标应用程序的音频输出通道异常。When the target application plays audio data, the electronic device can monitor the audio output channel currently used to play the audio data. If the audio output channel is consistent with the default audio output channel corresponding to the audio mode of the target application, it can be considered The audio output channel used by the target application to play audio data is normal; otherwise, the audio output channel used by the target application to play audio data is abnormal. For example, when an electronic device calls, its ringtone is sent from the earpiece channel or its ringtone is sent from the headset channel, it can be considered that the audio output channel of the target application used to play the ringtone is abnormal.
需要说明的是,音频数据包括语音数据、铃声数据、闹铃数据、多媒体数据(视频流、音频流输数据等)等等。It should be noted that the audio data includes voice data, ringtone data, alarm data, multimedia data (video streaming, audio streaming data, etc.) and so on.
步骤306,当音频输出通道异常时,改变音频数据的音频输出通道,以使改变后的音频输出通道播放音频数据。 Step 306, when the audio output channel is abnormal, the audio output channel of the audio data is changed, so that the changed audio output channel plays audio data.
电子设备可判断当前用于播放音频数据的音频输出通道是否异常,当音频输出通道异常时,可以改变当前用于播放音频数据的音频输出通道,以使改变后的音频输出通道来播放目标应用程序控制播放的音频数据。例如,电子设备来电时,其铃声从听筒通道发出或其铃声从耳机通道发出时,电子设备可以将当前用于播放铃声的听筒通道或耳机通道切换为扬声器通道,由扬声器来播放该音频数据。The electronic device can determine whether the audio output channel currently used to play audio data is abnormal. When the audio output channel is abnormal, the audio output channel currently used to play audio data can be changed so that the changed audio output channel can play the target application Control audio data for playback. For example, when an electronic device calls, the ringtone is sent from the earpiece channel or the ringtone is sent from the earphone channel, the electronic device can switch the earphone channel or the earphone channel currently used to play the ringtone to the speaker channel, and the audio data is played by the speaker.
上述音频输出控制方法,能够获取目标应用程序的音频模式;根据音频模式监听目标应用程序用于播放音频数据的音频输出通道是否异常;当音频输出通道异常时,改变音频数据的音频输出通道,以使改变后的音频输出通道播放音频数据,可以修复异常的音频输出通道,自动使音频数据从默认的音频输出通道输出,增强音频数据输出的稳定性,可以避免音频数据从其他音频输出通道输出的情况发生,提高用户体验。The above audio output control method can obtain the audio mode of the target application; monitor whether the audio output channel used by the target application to play audio data is abnormal according to the audio mode; when the audio output channel is abnormal, change the audio output channel of the audio data to Make the changed audio output channel play audio data, can repair abnormal audio output channel, automatically make the audio data output from the default audio output channel, enhance the stability of the audio data output, can avoid the audio data output from other audio output channels The situation occurs, improving the user experience.
如图4所示,在一个实施例中,根据音频模式监听目标应用程序用于播放音频数据的音频输出通道是否异常,包括As shown in FIG. 4, in one embodiment, monitoring the audio output channel used by the target application to play audio data according to the audio mode is abnormal, including
步骤402,当目标应用程序播放音频数据时,监听播放音频数据的音频输出通道。Step 402: When the target application plays audio data, monitor the audio output channel that plays the audio data.
在一个实施例中,基于电子设备的操作系统创建监听模块,通过监听模块对目标应用程序的音频输出通道进行监听。其中,该监听模块还可以用于监听目标应用程序的音频模式、音量调节、录音等与音频数据输入和/或输出相关的信息。以具有安卓操作系统的电子设备为例,可在系统框架层(native/framework层)创建系统级的监听模块(AtlasService模块),通过监听模块对目标应用程序的音频输出通道和音频模式进行监听。例如,可在框架层设立监听模块并运行在系统服务程序(system_server)中,由于该监听模块设立在系统级的服务框架层中,可方便与其他系统服务进行交互,同时无需担心系统调用时的权限问题。In one embodiment, a monitoring module is created based on the operating system of the electronic device, and the audio output channel of the target application program is monitored through the monitoring module. Wherein, the monitoring module can also be used to monitor the audio mode, volume adjustment, recording and other information related to the input and/or output of audio data of the target application. Taking an electronic device with an Android operating system as an example, a system-level monitoring module (AtlasService module) can be created at the system framework layer (native/framework layer) to monitor the audio output channel and audio mode of the target application 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.
可选的,电子设备也可以创建独立的监听进程,通过消息传输机制监听目标应用程序的音频输出通道。在该进程中设立并调用单独的监听函数,可设置为开机自启动,并实时对其他任何一个目标应用程序的音频模式设置以及播放音频数据的音频输出通道进行监控。Optionally, the electronic device can also create an independent monitoring process to monitor the audio output channel of the target application through the message transmission mechanism. In this process, a separate monitoring function is set up and called, which can be set to start automatically after power-on, and monitor the audio mode setting of any other target application and the audio output channel that plays audio data in real time.
步骤404,识别音频输出通道是否符合音频模式的播放标准。Step 404: Identify whether the audio output channel conforms to the audio mode playback standard.
步骤406,当音频输出通道不符合音频模式的播放标准时,则音频输出通道异常。 Step 406, when the audio output channel does not meet the playback standard of the audio mode, the audio output channel is abnormal.
电子设备中还可预先构建音频输出通道与音频模式匹配映射表;在该映射表中,会存储音频模式的所有音频输出通道以及默认音频输出通道,其中,默认音频输出通道可理解为该目标应用程序播放音频数据时,用于播放该音频数据的音频输出通道具有最高优先级,也即,默认音频输出通道的在所有音频输出通道中的播放优先级最高。若采用默认音频输出通道播放音频数据时,则可认为符合音频模式的播放标准。Electronic equipment can also pre-construct a mapping table of audio output channels and audio mode matching; in this mapping table, all audio output channels of the audio mode and the default audio output channel are stored, where the default audio output channel can be understood as the target application When a program plays audio data, the audio output channel used to play the audio data has the highest priority, that is, the default audio output channel has the highest playback priority among all audio output channels. If the default audio output channel is used to play audio data, it can be considered to comply with the playback standards of the audio mode.
根据映射表,识别音频输出通道是否符合音频模式的播放标准。例如,控制播放音频数据的目标应用程序为视频类应用程序,其音频模式为多媒体模式,该 多媒体模式对应的默认音频输出通道为扬声器通道。若该视频类应用程序播放视频时,其音频数据由听筒通道发出,而多媒体模式的播放标准为音频数据由扬声器通道发出,则可认为该听筒通道不符合多媒体模式的播放标准。According to the mapping table, identify whether the audio output channel meets the playback standards of the audio mode. For example, the target application that controls the playback of audio data is a video application, and its audio mode is a multimedia mode, and the default audio output channel corresponding to the multimedia mode is a speaker channel. If the video application plays the video, the audio data is sent from the earphone channel, and the multimedia mode playback standard is that the audio data is sent from the speaker channel, it can be considered that the earphone channel does not meet the multimedia mode playback standard.
当音频输出通道不符合音频模式的播放标准时,则音频输出通道异常。When the audio output channel does not meet the playback standards of the audio mode, the audio output channel is abnormal.
如图5所示,在一个实施例中,当音频输出通道异常时,改变音频数据的音频输出通道,包括:As shown in FIG. 5, in one embodiment, when the audio output channel is abnormal, changing the audio output channel of the audio data includes:

步骤504,根据预设接口函数改变音频数据的音频输出通道。Step 504: Change the audio output channel of the audio data according to the preset interface function.
当播放音频数据的音频输出通道异常时,电子设备可以调用预设接口函数来设置音频输出通道。预设接口函数至少包括setSpeakerphoneOn()接口函数、setMode(AudioManager.MODE_IN_CALL)接口函数、isWiredHeadsetOn()接口函数或其他用于设置听筒通道、耳机通道的接口函数等。When the audio output channel playing audio data is abnormal, the electronic device can call a preset interface function to set the audio output channel. 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 headphone channel.
例如,基于安卓操作系统的电子设备中,电子设备可以通过调用AudioManager中的接口函数setSpeakerphoneOn()来设置扬声器通道,也即,可以开启或关闭扬声器通道。电子设备可以通过调用AudioManager中的函数setMode(AudioManager.MODE_IN_CALL)或构造参数streamType(STREAM_VOICE_CALL)设置听筒通道;电子设备可以通过调用AudioManager中的函数isWiredHeadsetOn()来设置并检测听筒通道。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.
可选的,接口函数setMode()可用于设置声音模式,例如,void setMode(intmode)。其中,可设置的值有NORMAL,RINGTONE和IN_CALL。例如,setRingerMode(intringerMode)可用于设置电话铃声的模式,其包括正常铃声(RINGER_MODE_NORMAL)、铃声静音(RINGER_MODE_SILENT)和震动(RINGER_MODE_VIBRATE)。Optionally, the interface function setMode() can be used to set the sound mode, for example, void setMode(intmode). Among them, the settable values are NORMAL, RINGTONE and IN_CALL. For example, setRingerMode (intringerMode) can be used to set the ringtone mode of the phone, which includes normal ringtone (RINGER_MODE_NORMAL), ringtone silence (RINGER_MODE_SILENT), and vibration (RINGER_MODE_VIBRATE).
