具体实施方式
为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施例。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容的理解更加透彻全面。
可以理解，本发明所使用的术语“第一”、“第二”等可在本文中用于描述 各种元件，但这些元件不受这些术语限制。这些术语仅用于将第一个元件与另一个元件区分。举例来说，在不脱离本发明的范围的情况下，可以将第一音频传输通道称为第二音频传输通道，且类似地，可将第二音频传输通道称为第一音频传输通道。第一音频传输通道和第二音频传输通道两者都是音频传输通道，但其不是同一音频传输通道。
在一个实施例中，如图1所示，提供了一种电子设备的内部结构示意图。该电子设备包括通过系统总线连接的处理器、存储器和显示屏。其中，该处理器用于提供计算和控制能力，支撑整个电子设备的运行。存储器用于存储数据、程序、和/或指令代码等，存储器上存储至少一个计算机程序，该计算机程序可被处理器执行，以实现本申请实施例中提供的适用于电子设备的通话控制方法。存储器可包括磁碟、光盘、只读存储记忆体(Read-Only Memory，ROM)等非易失性存储介质，或随机存储记忆体(Random-Access-Memory，RAM)等。例如，在一个实施例中，存储器包括非易失性存储介质及内存储器。非易失性存储介质存储有操作系统、数据库和计算机程序。该数据库中存储有用于实现以上各个实施例所提供的一种通话控制方法相关的数据，比如可存储有每个进程或应用的名称等信息。该计算机程序可被处理器所执行，以用于实现本申请各个实施例所提供的一种通话控制方法。内存储器为非易失性存储介质中的操作系统、数据库和计算机程序提供高速缓存的运行环境。显示屏可以是触摸屏，比如为电容屏或电子屏，用于显示前台进程对应的应用的界面信息，还可以被用于检测作用于该显示屏的触摸操作，生成相应的指令，比如进行前后台应用的切换指令等。
本领域技术人员可以理解，图1中示出的结构，仅仅是与本申请方案相关的部分结构的框图，并不构成对本申请方案所应用于其上的电子设备的限定，具体的电子设备可以包括比图中所示更多或更少的部件，或者组合某些部件，或者具有不同的部件布置。如该电子设备还包括通过系统总线连接的网络接口，网络接口可以是以太网卡或无线网卡等，用于与外部的电子设备进行通信，比如可用于同服务器进行通信。
在一个实施例中，如图2所示，提供了一种Android音频系统的部分架构图。其中，该Android音频系统的架构系统中包括内核(Kernel)空间层210、本地层220、框架层230以及Client层240。
内核(Kernel)空间层210上可包含Audio驱动模块211，其中，Audio驱动模块是与硬件进行交互，并且实现本地层的接口供上层正常调用，这里可以选择ALSA，OSS以及自定义的音频驱动。本地层220中包含AtlasService_Jni 模块221、AtlasService Interface模块223以及AtlasService模块225。框架层230中包含AtlasManager模块231和AtlasService模块233。其中，AtlasManager模块231中设有常规接口和注册回调接口。本地层220中的AtlasService模块225以及框架层230中的AtlasService模块233用于事件接收和处理、信息收集、异常反馈以及日志收集，其中，信息收集可包括显示信息的收集和音频信息的收集。其中，音频信息包括播放信息、录音信息、音频模式设置信息等。由于该AtlasService模块设立在系统级的框架层中，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。通过上述的架构，可实现本申请各个实施例中的通话控制方法。
在一个实施例中，如图3所示，提供了一种通话控制方法，该通话控制方法应用于具有多个音频传输通道的电子设备。在一个实施例中，电子设备可以为包括手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(Mobile Internet Device，MID)、可穿戴设备(例如智能手表、智能手环、计步器等)或其他等具有语音通话功能并具有扬声器的电子设备。
音频传输通道包括听筒通道、扬声器通道、耳机通道；还可以包括麦克风通道，在本申请实施例中，字音频传输通道可以为听筒通道、扬声器通道和耳机通道，其中，耳机通道可以包括有线耳机通道和蓝牙耳机通道。当音频传输通道为听筒通道时，通话语音由听筒发出；当音频传输通道为扬声器通道时，通话语音由外放扬声器发出；当音频传输通道为耳机通道时，通话语音可通过有线耳机或蓝牙耳机发出。
如图3所示，在一个实施例中，通话控制方法，包括步骤302-步骤306。
步骤302，获取电子设备处于通话状态的第一音频传输通道。
当电子设备处于通话状态时，可以获取当前通话状态所占用的第一音频传输通道。例如，可以基于电子设备中内置的安卓操作系统，新建一个Java类用来监听电子设备是否处于通话状态，具体地可以通过BroadcastReceiver的重载进行监听。
当电子设备处于通话状态时，电子设备可以获取当前通话状态的第一音频传输通道。其中，第一音频传输通道包括听筒通道、扬声器通道、有线耳机通道和蓝牙耳机通道。若第一音频传输通道为听筒通道时，则表明电子设备的通话语音由听筒输出；若第一音频传输通道为扬声器通道时，则表明电子设备的通话语音由扬声器输出；若第一音频传输通道为耳机通道时，则表明电子设备的通话语音由耳机输出。例如，可以基于电子设备中内置的安卓操作系统，可调用系统函数AudioModeProvider.getAudioMode()来获取当前通 话状态所占用的第一音频传输通道。
步骤304，监听目标应用程序在通话状态中是否产生用于设置第二音频传输通道的操作。
电子设备在通话状态时，还可以实时检测目标应用程序在通话状态中是否产生用于设置第二音频传输通道的操作。其中，目标应用程序可以理解为能够输出和/或输出音频信号的应用程序，且目标应用程序的数量可以为1个2个、3个或更多个。例如，目标应用程序可包括即时通信类、音频播放类、视频播放类、声音控制类、语音输入类等应用程序。
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。
在一个实施例中，电子设备可通过内置的监听函数对目标应用程序的音频行为进行监听。该音频行为包括播放行为、录音行为以及音频模式设置等行为。其中，音频模式设置可以理解为产生了用于设置第二音频传输通道的操作。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，通过所述监听模块对目标应用程序的音频行为进行监听。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。
可选的，电子设备也可以创建独立的监听进程，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行为进行监控。
步骤306，当目标应用程序在后台运行且产生操作时，禁止目标应用程序开启第二音频传输通道，以维持第一音频传输通道进行通话。
在一个实施例中，电子设备可以获取目标应用程序的运行状态，该运行状态可包括前台运行或后台运行。例如，电子设备可以监听目标应用程序的进程信息，并根据进程信息来确定目标应用程序的运行状态。电子设备还可以基于使用ActivityLifecycleCallbacks来监听目标应用程序是否运行在后台的行为，根据Activity的生命周期，其中，onStart()表示一个Activity处于前台，onStop()表示Activity在后台不可见。当然，电子设备还可以通过getRunningTasks获取目标应用程序的运行状态，还可以通过getRunningTasks和RunningAppProcessInfo结合获取目标应用程序的运行状态。在此，对电子设备如何获取目标应用程序的运行状态不做进一步的限定，也不限于上述举例说明。
当电子设备监听到，目标应用程序当前处于后台运行，且在目标应用程序产生了用于设置第二音频传输通道的操作时，则该电子设备可以禁止目标应用程序开启第二音频传输通道，以维持第一音频传输通道进行通话。也即，虽然目标应用程序在后台设置了第二音频传输通道，但是该设置动作不会被执行，也即，该目标应用程序不会开启第二音频出传输通道，以维持当前通话状态的第一音频传输通道。其中，第二音频传输通道也可包括听筒通道、扬声器通道、有线耳机通道和蓝牙耳机通道。其中，第一音频传输通道与第二音频传输通道不同。
例如，通话状态的第一音频传输通道为听筒通道时，而目标应用程序运行在后台，且设置了第二音频传输通道，其中，第二音频传输通道为扬声器通道或耳机通道，也即，目标应用程序设置第二音频传输通道的目的是为了调用扬声器通道或耳机通道。若目标应用程序开启该第二音频传输通道时，其电子设备的通话语音则回从扬声器或耳机通道输出。电子设备可通过禁止目标应用程序开启第二音频传输通道，以维持第一音频传输通道进行通话，也即，当前的通话语音还是以第一音频传输通道输出，进而可以避免通话过程中，音频输出通道发生改变的情况发生。
上述通话控制方法，可以获取所述电子设备处于通话状态的第一音频传输通道；监听目标应用程序在所述通话状态中是否产生用于设置第二音频传输通道的操作；当所述目标应用程序在后台运行且产生所述操作时，禁止所述目标应用程序开启所述第二音频传输通道，以维持所述第一音频传输通道进行通话，以维持当前通话语音还是以第一音频传输通道，可以避免通话过程中音频输出通道发生改变的情况发生，提高用户体验度。
如图4所示，在一个实施例中，通话控制方法包括步骤402-步骤410。其中，
步骤402，获取电子设备处于通话状态的第一音频传输通道。
步骤404，监听目标应用程序在通话状态中是否调用预设接口函数。
电子设备可以监听目标应用程序在通话状态中是否调用预设接口函数，其中，预设接口函数用于设置传输音频的第二音频传输通道。任何目标应用程序均可以调用该预设接口函数时，当预设接口函数的功能有效时，则该目标应用程序可开启该第二音频传输通道，而当预设接口函数的功能无效时，则该目标应用程序可调用但不开启该第二音频传输通道。具体的，电子设备可以通过对预设接口函数进行设置，以确定该预设接口函数功能的有效或无效性。
进一步的，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。
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。
预设接口函数不限于上述举例说明，还可以根据实际需求来设定不同形式的预设接口函数。
进一步的，电子设备可以监听目标应用程序调用预设接口函数是否向音频设备状态管理器申请使用音频传输通道。若向音频设备状态管理器发出了申请，该表明该目标应用程序调用了预设接口函数，也即，目标应用程序用产生了用于设置第二音频传输通道的操作。
步骤406，判断目标应用程序是否在后台运行。
在一个实施例中，电子设备可以获取目标应用程序的运行状态，该运行状态可包括前台运行或后台运行，进而可以判断目标应用程序是否在后台运行。具体地，电子设备可以监听目标应用程序的进程信息，并根据进程信息来确定目标应用程序的运行状态。例如，电子设备可以基于ActivityManager.RunningAppProcessInfo来获取目标应用程序运行中进程信息。其中，进程信息包括常量类型信息和变量类型信息，根据获取的进程信息就可以判断目标应用程序是否在后台运行。
可选的，电子设备还可以基于ActivityLifecycleCallbacks来监听目标应用程序是否运行在后台的行为，根据Activity的生命周期，其中，onStart()表示一个Activity处于前台，onStop()表示Activity在后台不可见。
可选的，电子设备还可以通过getRunningTasks获取目标应用程序的运行状态，还可以通过getRunningTasks和RunningAppProcessInfo结合获取目标应用程序的运行状态。
在此，对电子设备如何获取目标应用程序的运行状态不做进一步的限定，也不限于上述举例说明。
步骤408，当目标应用程序在后台运行且产生操作时，允许目标应用程序调用预设接口函数，且预设接口函数的功能失效，以维持第一音频传输通 道进行通话。
在一个实施例中，若目标应用程序在后台运行时产生了用于设置第二音频传输通道的操作时，其允许目标应用程序调用该预设接口函数，且该预设接口函数的功能失效，以维持第一音频传输通道进行通话。
在一个实施例中，当通话状态的第一音频通道为听筒通道时，允许目标应用程序调用第二预设函数，且第二预设函数功能失效，以维持听筒通道进行通话，其中，第二预设函数用于设置扬声器通道，或，第二预设函数还用于设置耳机通道。例如，当通话语音为听筒通道输出时，其在后台运行的目标应用程序调用了用于设置扬声器通道或耳机通道的预设函数功能时，电子设备可以是该预设接口函数的功能无效，仍维持当前通话语音的听筒通道输出，能够使通话语音从听筒通道输出，而避免改变通话语音的输出通道。
在一个实施例中，当第一音频通道为扬声器通道时，允许目标应用程序调用第二预设函数，且第二预设函数功能失效，以维持扬声器通道进行通话；其中，第二预设函数用于设置听筒通道，还用于设置耳机通道。例如，当通话语音为扬声器通道输出时，其在后台运行的目标应用程序调用了用于设置听筒通道或耳机通道的预设函数功能时，电子设备可以是该预设接口函数的功能无效，仍维持当前通话语音的扬声器通道输出，能够使通话语音从扬声器通道输出，而避免改变通话语音的输出通道。
当第一音频通道为耳机通道时，允许目标应用程序调用第二预设函数，且第二预设函数功能失效，以维持耳机道进行通话，其中，第二预设函数用于设置听筒通道，还用于设置扬声器通道。例如，当通话语音为耳机通道输出时，其在后台运行的目标应用程序调用了用于设置听筒通道或扬声器通道的预设函数功能时，电子设备可以是该预设接口函数的功能无效，仍维持当前通话语音的耳机通道输出，能够使通话语音从耳机通道输出，而避免改变通话语音的输出通道。
本实施例中的通话控制方法，在通话过程中，处于后台运行的目标应用程序虽然能够调用用于设置第二音频传输通道的预设接口函数，但是可以控制该调用的预设接口函数的功能无效，以维持当前通话语音的第一音频传输通道，能够使第一音频传输通道状态及相关参数均正常，从而避免改变通话语音的输出通道的情况发生，提高了用户通话过程中的体验度。
如图5所示，在一个实施例中，通话控制方法包括步骤502-步骤506：
步骤502：获取终端处于通话状态的第一音频传输通道。
步骤504：监听目标应用程序在通话状态中是否产生用于设置第二音频 传输通道的操作。
上述步骤502、步骤504与前述实施例中步骤302、步骤304一一对应，在此，不再赘述。
步骤506：当目标应用程序在前台运行且设置的第二传输通道符合预设条件时，允许目标应用程序启用第二音频传输通道，以使目标应用程序通过第二音频传输通道进行音频传输。
电子设备可以基于ActivityLifecycleCallbacks来监听目标应用程序是否运行在前台的行为。同时，电子设备可以监听在前台运行的目标应用程序在通话状态中是否调用预设接口函数，其中，预设接口函数用于设置传输音频的第二音频传输通道。当在前台运行的目标应用程序在通话状态中调用了预设接口函数，也即目标应用程序在前台运行时产生了用于设置第二音频传输通道的操作时，可以判断设置的第二传输通道是否符合预设条件。
在一个实施例中，预设条件包括第二音频传输通道与第一音频传输通道不一致。也即，当目标应用程序在前台运行且设置的第二传输通道与第一音频传输通道不一致时，允许目标应用程序启用第二音频传输通道，以使目标应用程序通过第二音频传输通道进行音频传输。
例如，当通话状态的第一音频通道为听筒通道时，前台运行的目标应用程序设置的第二传输通道为扬声器通道，此时，目标应用程序若需要播放音频信号时，允许目标应用程序启用扬声器通道，以使目标应用程序通过扬声器通道进行音频传输。
进一步的，当第一音频传输通道的无通话语音输入时，允许目标应用程序启用扬声器通道时，并播放目标应用程序待播放的语音。
在一个实施例中，预设条件包括第二音频传输通道与第一音频传输通道一致且目标应用程序的使用优先级高于通话的使用优先级。也即，当目标应用程序在前台运行且设置的第二传输通道与第一音频传输通道一致且目标应用程序的使用优先级高于通话的使用优先级时，允许目标应用程序启用第二音频传输通道，以使目标应用程序通过第二音频传输通道进行音频传输。其中，使用优先级可以理解的是，当通话与目标应用程序都需要使用同一音频传输通道时，能够优先使用的等级。
具体的，当目标应用程序的使用优先级高于通话的使用优先级时，其该使用优先级为使用听筒通道时的优先级。也即，目标应用程序和通话在同时使用听筒通道时，在一定情况下，其目标应用程序的使用优先级高于通话的使用优先级时，可以在允许目标应用程序先使用听筒通道，以使目标应用程 序通过听筒通道进行音频传输。例如，当该目标应用程序为即时通信类应用程序，该目标应用程序中当前处于通讯状态的联系人A的重要性高于当前通话联系人B时，则可以认为目标应用程序的使用优先级高于通话的使用优先级。
如图6所示，在一个实施例中，允许目标应用程序启用第二音频传输通道，以使目标应用程序通过第二音频传输通道进行音频传输，包括步骤602-步骤604。其中，
步骤602，检测通话状态的闲置时间段。
在一个实施例中，电子设备可以在通话状态检测通话状态的闲置时间段。其中，在预设时间段内未检测出输入或输出语音信号的时间段称之为闲置时间段。可选的，若在预设时间段内输入和输出语音信号的超出人声范围的时间段称之为闲置时间段。其中，人声范围可以理解为声波的频率范围为20HZ-20KHZ，其中，人说话的声音范围只在人能够听到的声音范围中占较窄的一部分，一般在100HZ-8KHZ以内，而200-4000HZ被称为人声基频，大部分人说话的频率都在该范围内。当输入和输出语音信号的频率均不在人声范围内时，则认为该时间段为闲置时间段。
步骤604，在闲置时间段允许目标应用程序启用第二音频传输通道，以使目标应用程序通过第二音频传输通道进行音频传输。
电子设备能够在在闲置时间段允许目标应用程序启用第二音频传输通道，以使目标应用程序通过第二音频传输通道进行音频传输。也即，电子设备的通话状态的第一音频传输通道不会改变，同时在闲置时间段允许目标应用程序启用第二音频传输通道，以使目标应用程序通过第二音频传输通道进行音频传输。当目标应用程序通过第二音频传输通道进行音频传输完毕后，可以以第一音频传输通道恢复当前的通话状态，仍然不会改变第一音频传输通道状态及相关参数，提高了用户通话过程中的体验度以及使用目标应用程序的灵活性。
应该理解的是，虽然图3-6的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，这些步骤可以以其它的顺序执行。而且，图3-6中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，这些子步骤或者阶段的执行顺序也不必然是依次进行，而是可以与其它步骤或者其它步骤的子步骤或者阶段的至少一部分轮流或者 交替地执行。
