具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同 或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
下面参考附图描述本公开实施例的相机应用的占用控制方法和装置。相关技术中，依赖于到相机应用提供功能服务的应用，在占用相机应用时，如果通过触发home键退出挂载在后台，或者，在占用相机的应用界面直接触发电源键灭屏，可能存在两种情况，一类是相机应用没有关闭，并且一直在后台向相机设备请求数据；另一类为不请求相机数据，但也不关闭相机设备，由此，导致了终端设备功耗的增加，降低了终端设备的续航能力。在本公开中提供的相机应用的占用控制方法中，根据相机应用被占用时的具体情况，准确筛选出不必要的占用情况，并进行优化，由此，减小了对终端设备的功耗，提高了终端设备的续航能力。
图1为本公开实施例所提供的一种相机应用的占用控制方法的流程示意图。如图1所示，该方法包括以下步骤：
步骤101，当相机应用被前台运行的第一应用占用时，若确定终端设备处于预设的第一操作状态，则检测第一应用是否发送相机数据请求消息。
具体地，当相机应用被当前终端设备前台运行的第一应用占用时，为了判断当前第一应用占用该相机应用时的具体使用情况，确定终端设备的是否处于预设的第一操作状态，其中，预设的第一操作状态对应于占用相机应用的第一应用，可能会出现不必要占用情况的操作状态，为了检测当前第一应用在第一操作状态下是否正在利用相机应用进行功能服务，检测第一应用是否发送相机数据请求消息。
容易理解的是，如果第一应用发送相机数据请求，则表示当前第一应用调在请求相机数据，并没有将调用相机应用后对对应的进程闲置，此时，需要进一步判断第一应用请求相机数据后，是否为了提供功能服务。
需要说明的是，根据应用场景的不同，检测第一应用是否发送相机数据请求消息的方式不同，示例如下：
作为一种可能的实现方式，如图2所示，检测第一应用是否发送相机数据请求消息的方式不同的步骤包括：
步骤201，在获取到第一应用发送的相机数据请求查询指令后，确定获取到相机数据请求查询指令的第一占用时间和第一应用标识。
其中，第一占用时间可以通过查询当前系统时刻获取。
步骤202，获取数据请求接口中已经记录的应用标识信息和对应的占用时间，获取最近一次与第一应用标识匹配的第二占用时间。
应当理解的是，在实际执行过程中，当相机应用被调用时，会执行相机数据请求的接 口，并在该接口中记录相机数据请求的应用标识和请求时间，其中，应用标识包括应用调用相机应用的进程ID或者应用程序包名称等能唯一标识应用程序的标识信息。
在本公开的实施例中，在第一应用向相机应用发送相机数据请求消息时，在与相机应用对应的数据请求接口中记录第一应用占用相机应用的第一占用时间和第一应用标识，以便于根据该记录进一步检测第一应用是否将调用相机应用对对应的进程闲置。
具体地，在获取到相机数据请求查询指令后，获取数据请求接口中记录的应用标识信息和对应的占用时间，获取在获取到相机数据请求查询指令之前记录的应用标识信息和对应的占用时间中，距离当前获取到相机数据请求查询指令的时刻最近一次与第一应用标识匹配的第二占用时间，即获取在获取到相机数据请求查询指令之前，最后一次记录的第一应用发送相机数据请求消息的时间。
步骤203，检测第一占用时间与第二占用时间的时间差值是否在第二预设时间范围内。
其中，第二预设时间范是根据大量实验数据标定的，可以为500ms等。
应当理解的是，如果第一应用将调用相机应用对对应的进程闲置，则当前发送相机数据请求查询指令的第一占用时间，相较于距离当前时刻最近时刻发送相机数据请求查询指令的第二占用时间的时间差较大，如果第一应用将调用相机应用对对应的进程没有闲置，则当前发送相机数据请求查询指令的第一占用时间，相较于距离当前时刻最近时刻发送相机数据请求查询指令的第二占用时间的时间差较小。
在本公开的实施例中通过检测第一占用时间与第二占用时间的时间差值是否在第二预设时间范围内，确定第一应用是否发送相机数据请求，也就是说，当第一占用时间与第二占用时间的时间差值在第二预设时间范围内，在确定为第一应用发送相机数据请求消息，否则，即使第一应用发送相机数据请求消息，但是相对于上次发送相机数据请求消息时间间隔较长，则认为没有接收到该相机数据请求消息。
步骤102，若检测到第一应用发送相机数据请求消息，则向相机应用发送延时第一时长的延时关闭消息，并检测在第一时长内终端设备的状态是否由第一操作状态切换至第二操作状态。
其中，第一时长是根据大量实验数据标定的，可以为1分钟等。
具体地，如果检测到第一应用发送相机数据请求消息，则表明第一应用并没有在调用相机应用后对对应的进程闲置，此时，向相机应用发送延时第一时长的延时关闭消息，在该第一时长内，相机应用不会被关闭，应当理解的是，在该第一时长内，可以进一步判断当前第一应用是否正在利用相机应用进行功能服务，需要检测在第一时长内终端设备的状态是否由第一操作状态切换至第二操作状态，其中，可以理解的是，在第二操作状态下，第一应用对相机应用的占用都是必要的占用，不属于可被优化功终端设备功耗的情况。
需要强调的是，为了确保能够优化终端设备的功耗，上述第一时长应该小于终端设备系统设定的相机应用默认的关闭时长，其中，默认的关闭时长对应于相机应用在该默认关闭时长内如果没有被请求相机数据，则直接关闭的时长。
步骤103，若没有切换至第二操作状态，且检测到第一应用继续发送相机数据请求消息，则检测第一应用是否开启与相机数据请求相关的功能，若没有开启，则控制第一应用释放对相机应用的占用。
其中，与相机数据请求相关的功能包括进行视频聊天、直播类操作时进行的音频播放、音频录音、悬浮框播放器的功能等，在进行视频聊天以及直播类操作时，需要利用相机数据。
具体地，如果在第一时长内，第一应用没有切换至第二操作状态，且检测到第一应用仍然在继续发送相机数据请求消息，则检测第一应用是否开启与相机数据请求消息相关的功能，以判断当前第一应用向相机应用请求相机应用数据是否用于功能服务，若没有开启，则控制第一应用释放对相机应用的占用，以对终端设备的功耗进行优化。
当然，考虑到用户个性化需求，可能会要求某些第一应用始终占用相机应用，此时，还可以设置白名单应用，该白名单应用中的应用不参与本公开实施例的优化处理，即在控制第一应用释放对相机应用的占用之前，还需确定第一应用不属于预设的白名单应用。
在本公开的一个实施例中，如果检测到第一应用切换至第二操作状态，则表明当前第一应用请求相机数据用于进行功能服务，此时，移植之前发送的第一时长的延迟关闭消息，控制相机应用正常为第一应用提供功能服务。
在本公开的一个实施例中，如果检测到第一应用没有发送相机数据请求消息，则表明第一应用在调用相机应用后对对应的进程闲置，此时，还需要判断其他应用是否调用相机应用，即向相机应用发送延时第二时长的延时关闭消息，其中，根据大量实验数据研究，第二时长大于第一时长，比如，第一时长为一分钟，第二时长为两分钟，以为其他应用调用相机应用提供更多的冗余时间，避免相机应用反复开启关闭导致的功耗损失，在第二时长内，相机应用不关闭，在第二时长内，检测终端设备中是否具有第二应用打开相机应用，如果没有，则关闭相机应用，如果有，则移植之前发送的第二时长的延时关闭消息，相机应用正常为第二应用提供功能服务。
在实际执行中，为了满足用户的个性化需求，在上述实施例中，可以对相关操作进行用户提示，其中，在进行某些操作的提示时，可获取用户的主动确认操作。
在本公开的一个实施例中，在控制第一应用释放对相机应用的占用之前，还以预设的通知方式，比如以短信通知、弹窗通知等方式，向用户发送相机应用占用释放提示消息，其中，该提示消息中提供与接收用户确认操作的控件等，接收到用户针对该提示消息的确 认操作后，才释放相机应用。
在本公开一个实施例中，当对第一应用释放对相机应用的占用后，还可以以弹窗通知、短信通知、语音通知等方式向用户提示功耗已经优化的提示信息，比如，提示用户第一应用已经解除对相机应用的占用等。
基于以上描述可知，第一操作状态和第二操作状态分别对应于占用相机应用的第一应用，可能会出现不必要占用情况的操作状态，即属于功耗优化范围的状态，和，基本不可能会出现不必要占用情况的操作状态，即不属于功耗优化范围的状态，为了本领域的技术人员更加清楚，下面分别在不同的应用场景下，结合上述两种操作状态进行相机应用占用控制方法的描述。
其中，在以下应用场景中，第一时长为一分钟，第二时长为两分钟。
场景一：
在该场景下，终端设备的第一操作状态为亮屏状态下第一应用由前台切换至后台的操作状态，第二操作状态对应于亮屏状态下，第一应用由后台切换至前台运行的状态。
具体地，如图3-1所示，在终端设备亮屏时，若检测到占用相机应用的第一应用由前台切换至后台运行，则为了确定第一应用是否对占用相机应用的进程闲置，检测第一应用是否发送相机数据请求。
如果第一应用发送相机数据请求，则发送一个一分钟的延时关闭消息，控制相机应用在一分钟内不关闭，检测在一分钟内终端设备的状态是否由后台切换至前台运行，如果切换至前台运行则认为第一应用在使用相机应用提供功能服务，从而清除发送的延时关闭消息，控制相机应用进行正常的功能提供服务。
如果没有切换至前台运行则进一步判断第一应用请求相机数据是否是为了进行功能服务，检测第一应用在一分钟后是否继续发送相机数据请求消息，若继续发送，则检测第一应用是否在进行直播或者视频聊天等于相机数据请求相关的功能，如果有则不关闭相机应用，如果没有则控制第一应用释放对所述相机应用的占用，强制停止第一应用使用相机应用，并提示用户已经优化对终端设备的功耗，将第一应用对相机应用的不必要占用进行了清除。
在该实施例中，如果第一应用没有发送相机数据请求，则发送一个两分钟的延时关闭消息，在两分钟内检测当前前台运行的第二应用是否具有打开相机应用的行为，如果有则移除之前发送的两分钟的延时关闭消息，控制相机应用正常为第二应用提供功能服务，此时，覆盖掉或释放第一应用对相机应用的占用，如果两分钟内第二应用不具有打开相机应用的行为，则向用户发送提示消息询问是否优化第一应用占用相机应用的异常，如果用户确认优化，则释放第一应用对相机应用的占用。
场景二：
在该场景下，终端设备的第一操作状态对应于灭屏状态，第二操作状态对应于终端设备由灭屏状态切换为亮屏状态。
如图3-2所示，当第一应用占用相机应用时，确定终端设备是否灭屏，如果灭屏则检测第一应用是否发送相机数据请求消息，以确认第一应用占用相机应用的进程是否闲置，如果第一应用发送相机数据请求，则表明第一应用占用相机应用的进程没有闲置，此时，为了进一步判断第一应用是否在使用相机应用提供功能服务，向相机应用发送延时第一时长的延时关闭消息，并检测在一分钟内终端设备的状态是否由灭屏状态切换至亮屏状态，如果终端设备的状态是否由灭屏状态切换至亮屏状态，则认为第一应用在使用相机应用提供功能服务，从而，清除之前发送的一分钟的延时消息，控制相机应用正常提供功能服务。
如果在一分钟内终端设备的状态没有由灭屏状态切换至亮屏状态，则进一步判断第一应用是否在使用相机应用提供功能服务，一分钟后若检测到第一应用继续发送相机数据请求消息，则检测第一应用是否在进行直播或者视频聊天等于相机数据请求相关的功能，如果有则不关闭相机应用，如果没有则控制第一应用释放对相机应用的占用，强制停止第一应用使用相机应用，并提示用户已经优化对终端设备的功耗，将第一应用对相机应用的不必要占用进行了清除。
在该实施例中，如果第一应用没有发送相机数据请求，则发送一个两分钟的延时关闭消息，在两分钟内检测终端设备是否亮屏，并且在亮屏后前台运行的第二应用是否具有打开相机应用的行为，如果有则移除之前发送的两分钟的延时关闭消息，控制相机应用正常为第二应用提供功能服务，此时，覆盖掉或释放第一应用对相机应用的占用，如果两分钟内第二应用不具有打开相机应用的行为，则向用户发送提示消息询问是否优化第一应用占用相机应用的异常，如果用户确认优化，则释放第一应用对相机应用的占用。
综上，本公开实施例的相机应用的占用控制方法，当相机应用被前台运行的第一应用占用时，若确定终端设备处于预设的第一操作状态，则检测第一应用是否发送相机数据请求消息，若检测到第一应用发送相机数据请求消息，则向相机应用发送延时第一时长的延时关闭消息，并检测在第一时长内终端设备的状态是否由第一操作状态切换至第二操作状态，进而，若没有切换至第二操作状态，且检测到第一应用继续发送相机数据请求消息，则检测第一应用是否开启与相机数据请求相关的功能，若没有开启，则控制第一应用释放对相机应用的占用。由此，根据应用占用相机应用时，对相机应用的使用情况，对不必要的占用进行优化，降低了终端设备的功耗，提高了终端设备的续航能力。
