具体实施方式
为了使本申请的技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
图1为一个实施例中应用程序数据恢复方法的应用环境图。参照图1，该应用程序数据恢复方法应用于应用程序数据恢复系统。应用程序数据恢复系统包括终端110和服务器120，其中终端110通过网络与服务器120连接。终端110可以是固定终端或移动终端，固定终端具体可以是打印机、扫描仪和监控器中的至少一种，移动终端具体可以是平板电脑、智能手机、个人数据助理和数码相机中的至少一种。
图2为一个实施例中图1应用程序数据恢复系统中的终端110的内部结构示意图。如图2所示，该终端110包括通过系统总线连接的处理器、非易失性计算机可读存储介质、内存储器和网络接口。终端110的处理器用于提供计算和控制能力，支撑整个终端110的运行，存储器用于存储数据、代码指令等，网络接口用于与服务器120进行网络通信。存储器上存储有至少一个计算机可读指令，该计算机可读指令可被处理器执行，以实现本申请实施例中提供的适用于终端110的应用程序数据恢复方法。存储器可包括磁碟、光盘、只读存储记忆体(Read-Only Memory，ROM)等非易失性计算机可读存储介质，或随机存储记忆体(Random Access Memory，RAM)等。例如，在一些实施例中，存储器包括非易失性计算机可读存储介质及内存储器；非易失性计算机可读存储介质存储有操作系统和计算机可读指令，该计算机可读指令可被处理器执行以实现上述的业务编号分配方法；内存储器为非易失性计算机可读存储介质中的操作系统及计算机可读指令提供高速缓存的运行环境。
如图3所示，在一些实施例中，提供一种应用程序数据恢复方法，本实施例以该方法应用在终端110来举例说明，该方法具体包括以下步骤：
S302，获取应用程序开启指令。
在一些实施例中，终端110中安装有应用程序，终端110的显示屏中显示应用程序的应用图标，用户通过应用图标开启终端110中安装的应用程序。服务器120为终端110安装的应用程序对应的服务器。终端110检测应用图标的点击操作，终端110在检测到应用图标的点击操作时，触发应用图标对应的应用程序开启指令。
S304，根据应用程序开启指令开启应用主进程和应用辅助进程，应用主进程和应用辅助进程共享内存。
在一些实施例中，终端110获取应用程序开启指令后，提取应用程序开启指令中的应用标识，开启应用标识对应的应用主进程和应用辅助进程。应用主进程和应用辅助进程的地址空间中的内存地址相同，应用主进程和应用辅助进程通过相同的内存地址共享内存地址对应的内存空间。其中，应用主进程对共享的内存中的应用程序数据进行数据处理，而应用辅助程序不对共享的内存中的应用程序数据进行任何数据处理。
S306，检测应用主进程是否异常关闭。
在一些实施例中，终端110在开启应用主进程和应用辅助进程后，终端110在检测到应用主进程关闭时，获取应用主进程对应的进程参数，将获取到的进程参数与应用主进程对应的处于正常范围的进程参数进行参数比较，通过参数比较确定应用主程序是否为异常关闭。
在一些实施例中，终端110在检测到应用主进程关闭时，可以获取应用主进程中的线程数量，将获取到的线程数量与预设线程数量相比较。当应用主进程的线程数量超过预设线程数量时，则终端110检测到的应用主程序关闭为应用主程序的异常关闭。
在一些实施例中，终端110在检测到应用主进程关闭时，还可以获取应用主进程对应的处理器占用率，将获取到的处理器占用率与预设占用率相比较。当检测到应用主进程对应的处理器占用率超过预设占用率，则终端110检测到的应用主程序关闭为应用主程序的异常关闭。
S308，在检测到异常关闭时，保持应用辅助进程处于运行状态。
在一些实施例中，终端110在检测到应用主进程异常关闭时，不对应用辅助进程做任何处理，保持应用辅助进程仍然处于运行状态。在应用辅助进程处于运行状态时，应用主进程和应用辅助进程所共享的内存中的应用程序数据不会丢失，仍然会被存储在共享的内存中。
在一些实施例中，S308之后还包括关闭应用辅助进程的步骤，该步骤具体包括以下步骤：监测在预设时间段内应用主进程是否再次开启；当监测到应用主进程再次开启时，从应用辅助进程中获取内存地址；当监测到应用主进程未再次开启，关闭应用主进程对应的应用辅助进程。
在一些实施例中，终端110在检测到应用主进程异常关闭后，开始计时，并监测应用主进程是否再次开启。当所计时间达到预设时间段时，终端110仍未监测到应用主进程再次开启时，终端110查询与该应用主进程对应的应用辅助进程，并关闭查询到的应用辅助进程。当监测到应用主进程再次开启时，从应用辅助进程中获取内存地址。
S310，当应用主进程再次开启时，从应用辅助进程中获取内存地址。
在一些实施例中，在应用主进程异常关闭后，终端110在检测到应用主进程再次开启时，确定应用辅助进程的地址空间，从应用辅助进程的地址空间获取内存地址。内存地址为存储应用程序数据的内存空间所对应的唯一标识。
在一些实施例中，在应用主进程和应用辅助程序中设置有相同的地址空间标识。终端110在根据应用程序开启指令开启应用主进程和应用辅助进程时，分别应用主进程和应用辅助进 程中的地址空间标识对应的地址空间写入相同的内存地址。在应用主进程异常关闭后，终端110在检测到应用主进程再次开启时，获取再次开启的应用主进程中的地址空间标识。终端110根据获取的地址空间标识确定应用辅助进程中的地址空间，从确定的地址空间中获取内存地址。
S312，将获取到的内存地址写入再次开启的应用主进程，使应用主进程根据写入的内存地址进行应用程序数据恢复。
在一些实施例中，终端110在从处于运行状态的应用辅助进程中的地址空间获取到内存地址后，将获取到的内存地址写入再次开启的应用主进程中，使应用主进程根据写入的内存地址访问内存空间，从访问的内存空间中获取应用主进程异常关闭前的应用程序数据。终端110通过应用主进程获取应用主进程异常关闭前的应用程序数据，根据获取到的应用程序关闭数据恢复应用主进程异常关闭前应用程序页面。
本实施例中，根据应用程序开启指令开启应用主进程和应用辅助进程后，在检测到应用主进程异常关闭时，保持应用辅助进程处于运行状态。其中，应用主进程和应用辅助进程共享内存，应用主进程和应用辅助进程的内存地址相同，在保持应用辅助进程处于运行状态时，保证了内存地址对应的内存空间中的应用程序数据不会丢失。当应用主进程再次开启时，将应用辅助进程中的内存地址写入再次开启的应用主进程，使应用主进程根据写入的内存地址获取异常关闭前的应用程序数据进行数据恢复，避免了由于应用程序异常关闭导致应用程序数据丢失的情况，提高了应用程序数据的安全性。
如图4所示，在一些实施例中，S304具体包括开启共享内存的应用进程的步骤，该步骤具体包括以下内容：
S402，获取应用程序开启指令中的应用所需内存容量。
在一些实施例中，应用程序开启指令中包括应用程序对应的应用所需内存容量。终端110对应用程序开启指令进行解析，通过解析获取应用程序开启指令中的应用所需内存容量。
S404，根据应用所需内存容量确定内存空间，并获取确定的内存空间的内存地址。
在一些实施例中，终端110提取到应用所需内存容量后，根据应用所需内存容量确定空余的内存空间，并获取确定的内存空间的内存地址。
S406，开启应用主进程和应用辅助进程。
在一些实施例中，终端110提取应用程序开启指令中的应用标识，根据应用标识获取进程参数，根据进程参数开启与应用标识对应的应用主进程和应用辅助进程。
S408，将获取的内存地址分别写入应用主进程和应用辅助进程的地址空间。
在一些实施例中，终端110分别查询开启的应用主进程和应用辅助进程中的地址空间，将获取到的内存地址分别写入应用主进程和应用辅助进程的地址空间，以将获取到的内存地址对应的内存空间分配至应用主进程和应用辅助进程，使应用主进程和应用辅助进程共享获取到的内存地址对应的内存空间。
本实施例中，根据应用程序开启指令中的应用所需内存容量确定空闲的内存空间，将确定的内存空间对应的内存地址写入应用主进程和应用辅助进程的地址空间，保证应用主进程 和应用辅助进程可以共享写入的内存地址对应的内存空间。
如图5所示，在一些实施例中，S308之后具体还包括再次开启应用主进程的步骤，该步骤具体包括以下内容：
S502，展示是否开启应用程序的确认窗口。
在一些实施例中，终端110在应用主进程异常关闭后，获取应用主进程对应的应用标识，根据应用标识生成是否再次开启应用程序的提示信息，将生成的提示信息展示在是否开启应用程序的确认窗口中。
S504，获取根据确认窗口中触发的应用主进程开启指令。
在一些实施例中，确认窗口中展示有是否开启应用程序的提示信息，确认窗口中设置有“是”和“否”两个按钮，用户通过终端110的输入设备点击确认窗口中的按钮触发与点击的按钮相应的指令。终端110检测到“是”按钮被点击，触发应用程序开启指令；终端110检测到“否”按钮被点击，取消展示确认窗口。
S506，根据应用程序开启指令再次开启应用主进程。
在一些实施例中，终端110在获取到触发的应用程序开启指令，根据触发的应用程序开启指令再次开启应用主进程，使应用程序开启指令中应用标识对应的应用程序处于正常运行状态。
本实施例中，在应用程序的应用主进程异常关闭后，展示是否开启应用程序的确认窗口，保证用户可根据需要来确定相应的是否开启应用程序的指令，简化了开启应用程序的操作。
如图6所示，在一些实施例中，S312之前具体包括比较内存地址的步骤，该步骤具体包括以下内容：
S602，提取再次开启的应用主进程中的内存地址。
在一些实施例中，终端110在再次开启应用主进程后，获取再次开启的应用主进程的地址空间标识，提取地址空间标识对应的地址空间中的内存地址。
S604，将提取到的内存地址与获取到的内存地址进行比较。
在一些实施例中，终端110根据与应用主进程中相同的地址空间标识从处于运行状态的应用辅助进程的地址空间中获取内存地址，将提取到的内存地址与获取到的内存地址进行比较，若提取到的内存地址与获取到的内存地址相同，则无需对应用主进程的地址空间中的内存地址进行替换。
S606，若提取到的内存地址与所述获取到的内存地址不相同，将获取到的内存地址写入再次开启的应用主进程，使应用主进程根据写入的内存地址进行应用程序数据恢复。
在一些实施例中，若提取到的内存地址与获取到的内存地址不相同，终端110将再次开启的应用主进程中的内存地址替换为从应用辅助进程中获取到的内存地址，应用主进程根据替换的内存地址访问对应的内存空间，读取内存空间中的应用程序数据。终端110根据应用主进程读取到的应用程序数据恢复应用主进程异常关闭之前应用程序的页面。
本实施例中，通过将再次开启的应用主进程和应用辅助进程中的内存地址进行比较，通过比较确定再次开启的应用主进程和应用辅助进程中的内存地址不相同时，将再次开启的应 用主进程中的内存地址替换为应用辅助进程中的内存地址，保证再次开启的应用主进程中的内存地址的正确性，确保再次开启的应用主进程可以根据正确的内存地址进行应用程序数据恢复。

    当监测到所述应用主进程再次开启时，执行所述从所述应用辅助进程中获取内存地址的步骤；及
    当监测到所述应用主进程未再次开启，关闭所述应用主进程对应的所述应用辅助进程。
  19. 根据权利要求17所述的存储介质，其特征在于，所述在检测到异常关闭时，保持所述应用辅助进程处于运行状态之后，所述计算机可读指令被所述处理器执行时还执行以下步骤：
    展示是否开启应用程序的确认窗口；
    获取根据所述确认窗口中触发的应用程序开启指令；及
    根据所述应用程序开启指令再次开启所述应用主进程。
  20. 根据权利要求16-19中任一项所述的存储介质，其特征在于，所述将获取到的内存地址写入再次开启的应用主进程，使所述应用主进程根据写入的内存地址进行应用程序数据恢复之前，所述计算机可读指令被所述处理器执行时还执行以下步骤：
    提取再次开启的应用主进程中的内存地址；
    将提取到的内存地址与所述获取到的内存地址进行比较；及
    若所述提取到的内存地址与所述获取到的内存地址不相同，执行所述将获取到的内存地址写入再次开启的应用主进程，使所述应用主进程根据写入的内存地址进行应用程序数据恢复的步骤。
