本公开涉及计算机技术领域，具体地，涉及一种进程管理方法、装置、存储介质以及电子设备。
背景技术
在免安装技术中，寄宿应用运行在宿主应用的免安装框架(引擎)中，该免安装框架作为宿主应用的核心进程，用于提供寄宿应用运行所需的运行环境。对于寄宿应用而言，该核心进程相当于系统进程，管理着寄宿应用运行时的数据，如进程桩的计算、任务栈的计算等等。
由于该免安装框架运行在宿主应用上，其仅是宿主应用中的一个用于保存数据的后台进程。当内存不足时，系统会将处于后台运行的进程杀死，以释放内存。但是，由于寄宿应用的运行依赖于免安装框架，如何免安装框架的进程被系统回收，必然会导致寄宿应用无法运行。因此，如何在寄宿应用的运行过程中保证免安装框架的进程存活变得尤其重要。

寄宿应用是指从属于宿主应用，依赖于宿主应用所提供的运行环境而运行的应用程序。宿主应用可以简称为宿主，可以用于表示为集成模块提供运行环境的应用主体，例如，以运行在客户端中的宿主应用为社交应用为例，当社交应用中集成了小程序引擎的模块时，该社交应用可以具备打开并展示小程序的能力。又例如，以运行在客户端中的宿主应用为免安装平台为例，免安装平台集成有免安装框架(引擎)，该免安装平台可以运行其他原生应用程序。
寄宿应用运行在宿主应用的免安装框架(引擎)中，该免安装框架作为宿主应用的核心进程，用于提供寄宿应用运行所需的运行环境。由于寄宿应用的运行依赖于免安装框架，如果免安装框架的进程被系统回收，必然会导致寄宿应用无法运行。因此，如何在寄宿应用的运行过程中保证免安装框架的进程存活变得尤其重要。
在相关技术中，一般存在两种进程的保活方式。第一种是在免安装框架的进程被系统回收后，通过进程自我复活或被复活的方式继续运行。第二种是通过使用前台服务(foreground service)的方式提高进程的优先级。
针对第一种方式，由于寄宿应用运行在宿主应用的免安装框架中，数据均保存在内存中，如果免安装框架的进程被回收，将会导致内存数据丢失，即使重启免安装框架的进程，其运行状态也已经变得不一致。
针对第二种方式，通过前台服务的方式，只能将免安装框架的进程优先级提高至就“3”级，在免安装的应用场景中，免安装框架的进程依旧存在被系统回收的风险。其中，进程优先级从“0”到“15”表示优先级从高到低。当使用前台服务的方式提高免安装框架的进程优先级时，虽然免安装框架的进程优先级从后台进程的“15”级被提高至可见进程的“3”级，但是在前台运行的寄宿应用的进程优先级为“0”，导致系统(例如，安卓系统)在进行内存回收时，仍然可能会将免安装框架的进程进行回收，导致前台运行的寄宿应用出现闪退。而且，在免安装的应用场景下，使用前台服务提高免安装框架的进程优先级，会在显示界面中出现一个无法取消的通知栏，给用户的使用带来困扰。
针对上述技术问题，本公开实施例提供了一种进程管理方法、装置、存储介质以及电子设备。通过建立寄宿应用的进程优先级与宿主应用的目标进程的进程优先级之间的依赖关系，将目标进程的进程优先级与寄宿应用的进程优先级进程绑定，从而在寄宿应用的运行过程中将目标进程的进程优先级调整为与寄宿应用的当前进程优先级一致。其中，该依赖关系用于使得目标进程的进程优先级跟随寄宿应用的进程优先级的变化而变化。目标进程为宿主应用创建用于运行寄宿应用的虚拟运行环境所必须的进程。例如，当寄宿应用在前台运行时，寄宿应用的当前进程优先级为“0”级，根据该依赖关系，目标进程的进程优先级被调整为“0”级，从而保证宿主应用的免安装框架的进程的生命周期能够不低于寄宿应用的生命周期，避免出现目标进程被回收而导致寄宿应用崩溃的问题，保证了用户在使用寄宿应用时的良好用户体验。
下面将结合附图对本公开实施例提出的一种进程管理方法、装置、存储介质以及电子设备进行详细说明。
图1是根据一示例性实施例提供的一种进程管理方法的流程示意图。本公开实施例提供的进程管理方法可以通过电子设备执行，具体可以通过进程管理方法装置来执行，该装置可以有软件和/或硬件的方式实现，配置于电子设备中。请参考图1，本公开实施例提供的进程管理方法可以包括以下步骤。
S110，获取寄宿应用的当前进程优先级。
这里，寄宿应用的当前进程优先级是指寄宿应用在当前运行状态下的进程优先级。例如，当寄宿应用在前台运行时，其当前进程优先级为“0”级，当寄宿应用在后台运行时，其当前进程优先级为“3”级。其中，可以通过系统进程来确定寄宿应用的当前进程优先级。
S120，将所述寄宿应用对应的宿主应用的目标进程的进程优先级调整为与所述当前进 程优先级一致，所述目标进程为所述宿主应用创建用于运行所述寄宿应用的虚拟运行环境所必须的进程；其中，所述寄宿应用的进程优先级与所述目标进程的进程优先级之间存在依赖关系，所述依赖关系用于使得所述目标进程的进程优先级跟随所述寄宿应用的进程优先级的变化而变化。
这里，目标进程是指宿主应用创建用于运行寄宿应用的虚拟运行环境所必须的进程，该目标进程作为宿主应用的核心进程，其通过免安装框架为寄宿应用提供虚拟运行环境，寄宿应用并不安装在系统中，而是运行在该虚拟运行环境中。其中，目标进程可以是宿主应用的主进程，也可以是宿主应用的独立进程，用于管理寄宿应用运行时的数据。
依赖关系是指目标进程的进程优先级依赖于寄宿应用的进程优先级，在该依赖关系下，目标进程的进程优先级跟随寄宿应用的进程优先级变化而变化。根据该依赖关系，系统可以对目标进程的进程优先级进行调整。例如，当寄宿应用在前台运行时，寄宿应用的当前进程优先级为“0”级，根据该依赖关系，目标进程的进程优先级也为“0”级。当寄宿应用在后台运行时，寄宿应用的当前进程优先级为“3”级，根据该依赖关系，目标进程的进程优先级也为“3”级。
应当理解的是，该依赖关系实际上是将目标进程的进程优先级与寄宿应用的进程优先级进行绑定，以使得在寄宿应用的运行过程中，寄宿应用所依赖的目标进程不会被系统回收。
示例性地，在寄宿应用开始运行时，可以通过系统的服务组件来建立目标进程的进程优先级与寄宿应用的进程优先级之间的依赖关系。
由此，通过预先建立的寄宿应用的进程优先级与目标进程的进程优先级之间的依赖关系，将宿主应用的目标进程的优先级调整为与寄宿应用的当前进程优先级一致。使得在寄宿应用的运行过程中，宿主应用的目标进程的进程优先级与寄宿应用的当前进程优先级一致，确保了目标进程的生命周期不低于寄宿应用的生命周期，从而避免出现目标进程被回收而导致寄宿应用崩溃的问题，保证了用户在使用寄宿应用时的良好用户体验。
图2是根据一示例性实施例提供的建立依赖关系的流程示意图。如图2所示，依赖关系可以通过以下步骤建立。
S210，建立所述寄宿应用与所述目标进程之间的通信通道。
这里，在寄宿应用开始运行时，建立寄宿应用与目标进程之间的通信通道，通信通道用于寄宿应用与目标进程进行进程间通信(IInter-Process Communication，IPC)。即在寄宿应用开始运行时，控制寄宿应用与目标进程进行进程间通信。
在一些实施方式中，可以通过系统的进程通信组件建立寄宿应用与目标进程之间的通信通道。
其中，进程通信组件表示ContentProvider，为Android(安卓)四大组件之一，用于进程间的数据交互和共享。ContentProvider是Android系统中为开发者专门提供的不同应用间进行数据共享的组件，其提供了一套标准的接口用来获取以及操作数据，准许开发者把自己的应用数据根据需求开放给其他应用进行增删改查，而无须担心直接开放数据库权限而带来的安全问题。
在一些实施方式中，进程通信组件以稳固的方式建立寄宿应用与目标进程之间的通信通道。
这里，进程通信组件在建立通信通道时，可以使用稳固(stable)的方式或不稳固(unstable)的方式建立通信通道。其中，采用unstable类型的ContentProvider的应用程序不会因为远程ContentProvider进程的死亡而被杀，而采用stable类型的ContentProvider的应用程序会因为远程ContentProvider进程的死亡而被杀。
在免安装的应用场景中，通过控制进程通信组件通过稳固的方式建立寄宿应用与目标进程之间的通信通道。如果目标进程被系统回收，则前台运行的免安装应用也会被同步回收。
S220，获取所述通信通道对应的通信句柄，并将所述通信句柄缓存在所述寄宿应用的内存中，以建立所述依赖关系。
这里，通信句柄是指ContentProvider建立的通信通道的编号，每个通信通道都有唯一的编号。在寄宿应用通过ContentProvider与目标进程进行进程间通信时，目标进程的进程优先级会被提高至与通信来源进程一样的等级。其中，通信来源进程就是正在前台运行的寄宿应用的进程，其进程优先级为“0”级。
在寄宿应用与目标进程进行进程间通信时，将对应的通信句柄缓存在寄宿应用的内存中，并在进程间通信完成后，也不对该通信句柄进行释放。此时，系统会认为寄宿应用一直在与目标进程进行进程间通信，从而建立目标进程的进程优先级与寄宿应用的进程优先级之间的依赖关系。
例如，当寄宿应用在前台运行时，寄宿应用的优先级为“0”级，在将上述通信句柄缓存在寄宿应用的内存后，系统会认为寄宿应用一直在与目标进程进行进程间通信，从而将目标进程的进程优先级提高为与寄宿应用的进程优先级一致，即目标进程的进程优先级被提高为“0”级。
当寄宿应用退到后台运行时，寄宿应用的进程优先级从“0”级降低为“3”级，由于将该通信句柄缓存在寄宿应用的内存中，系统依旧会认为寄宿应用在与目标进程进行进程间通信，从而将目标进程的进程优先级提高为与寄宿应用的进程优先级一致，即目标进程的进程优先级为“3”级。
应当理解的是，如果不使用上述依赖关系来提升目标进程的进程优先级，当寄宿应用退到后台运行时，寄宿应用的进程优先级会降低为“13”级。显然，通过使用上述依赖关系，能够极大地提高目标进程的进程优先级，从而避免出现寄宿应用在运行过程中由于目标进程被系统回收而导致的闪退问题。
值得说明的是，由于将通信句柄缓存在寄宿应用的内存中，因此，当寄宿应用的内存被回收后，通信句柄也会被释放，从而解除目标进程的进程优先级与寄宿应用的进程优先级之间的依赖关系。
图3是根据另一示例性实施例提供的一种进程管理方法的流程示意图。如图3所示，该进程管理方法可以包括以下步骤。
S310，获取所述寄宿应用的当前运行状态。
这里，寄宿应用的当前运行状态是指寄宿应用的实时运行状态，如前台运行状态或后台运行状态等。其中，可以通过系统进程或宿主应用来感知寄宿应用的当前运行状态。
S320，根据所述当前运行状态，确定是否解除所述依赖关系。
这里，由于寄宿应用的运行依赖于宿主应用的目标进程，因此可以根据寄宿应用的当前运行状态来判断是否解除寄宿应用的进程优先级与目标进程的进程优先级之间的依赖关系。
在一些实施方式中，在所述当前运行状态表征所述寄宿应用处于前台运行或后台运行的情况下，维持所述依赖关系。
这里，当寄宿应用处于前台运行状态或后台运行状态时，寄宿应用依旧需要依赖目标进程创建的虚拟运行环境进行运行，因此，需要一直维持该依赖关系，以使目标进程的进程优先级能够与寄宿应用的进程优先级保持一致，从而避免目标进程的被系统回收。
作为一个示例，在通过上述通信句柄的方式建立依赖关系的情况下，维持该依赖关系的方式可以是继续将上述通信句柄存储在寄宿应用的内存中，即不对该通信句柄进行释放操作。
作为另一个示例，在通过系统的服务组件建立依赖关系的情况下，维持该依赖关系的方式可以是继续通过服务组件建立依赖关系。
在一些实施方式中，在所述当前运行状态表征所述寄宿应用退出运行的情况下，解除所述依赖关系。
这里，当寄宿应用退出运行时，目标进程无需继续为寄宿应用的运行创建虚拟运行环境，此时，可以解除目标进程的进程优先级与寄宿应用的进程优先级之间的依赖关系。即在寄宿应用退出运行后，目标进程的进程优先级不再跟随寄宿应用的进程优先级变化而变化。
作为一个示例，在通过上述通信句柄的方式建立依赖关系的情况下，解除该依赖关系的方式可以是将缓存在寄宿应用的内存中的通信句柄进行释放。此时，系统不再认为寄宿应用与目标进程在进程间通信，从而解除依赖关系。
应当理解的是，在寄宿应用退出运行之后，寄宿应用的内存被回收，存储在寄宿应用的内存中的通信句柄也会被同步释放。
值得说明的是，解除寄宿应用的进程优先级与目标进程的进程优先级的依赖关系是指在寄宿应用退出运行后解除该依赖关系。但是，当用户在退出寄宿应用A之后再启动寄宿应用B，则电子设备根据上述实施方式，重新建立寄宿应用B的进程优先级与目标进程的进程优先级的依赖关系。另外，当在宿主应用中同时运行多个寄宿应用时，可以存在多个依赖关系。当存在多个依赖关系时，目标进程的进程优先级跟随多个依赖关系中对应的最高进程优先级。
