参阅图1，为符合本发明一优选实施例中应用程序启动方法的流程示意图，所述应用程序启动方法包括以下步骤：
S101：于一智能终端内预设至少一个沙箱程序，所述沙箱程序内自定义一组用于处理输入事件的运行环境参数。
所述沙箱程序，简称沙箱，又被称为(sandbox)，用于构建限制程序运行的环境，是一种典型的安全模型。所述沙箱程序限制程序运行一方面是为了保护系统资源，同时另一方面也为了保护程序自己，免受恶意访问以及数据泄露。所述系统资源又包括CPU、内存、文件系统、网络等。例如在Java语言开发中，其安全模型的核心就是沙箱，可设 置不同的沙箱对应不同的系统资源访问限制，所有的Java程序运行都可以指定沙箱，可以定制安全策略。所述沙箱程序包括权限、代码源、保护域、策略文件、秘钥库等要素，用于对被保护的程序代码设定权限操作、保护范围以及各种安全策略。Java沙箱实现通过重写类加载器和安全管理器，通过设置的全局安全管理器来控制执行应用程序的权限。
本实施例中，所述沙箱程序设于所述智能终端内，其内部定义了一组用于处理输入事件的运行环境参数，以配置文件形式存储于所述智能终端内。对于安卓操作系统，各种应用程序的运行需要运行环境的支持，所述运行环境是一个广义的概念，体现为各种与应用程序相关的操作系统已定义的类或服务的集合，特别是各个类的属性和成员变量，支撑了应用程序运行所需的各种参数。本步骤预设所述沙箱程序时，所述沙箱程序内定义的运行环境参数分布在与处理输入事件有关的类中，所述运行环境参数可以是个别的类的成员变量，也可以对整个类进行再次定义。本步骤于所述沙箱程序内重新定义了与处理输入事件相关的类或类中的成员变量，并预设了对所述输入事件的监听，当有输入事件产生时，运行所述沙箱程序内定义的运行环境参数来对所述输入事件进行处理。所述沙箱程序内定义的运行环境参数并不限于对应用层的运行环境修改，还可能涉及系统运行库层或者驱动层；所述运行环境参数也不限于某个类、方法或服务，可以是多个类、方法或服务的集合，以实现所述应用程序所需的运行环境。
S102：运行所述沙箱程序。
本步骤运行所述沙箱程序，只有先运行了所述沙箱程序，才能为后续的应用程序运行提供相应的运行环境参数。运行所述沙箱程序，可通过多种方式实现，在开发阶段，可在开发环境下运行命令来启动沙箱程序，例如Java中运行打开安全管理器的命令；也可将沙箱程序的运行与相应的操作关联，例如将需要在沙箱程序内运行的应用程序放入同一个文件夹中，当用户打开该文件夹时，即触发所述沙箱程序的运行。所述沙箱程序运行后，启动对所述输入事件的相关接口的监听，以便对输入事件的处理进行劫持，所述操作系统内原有的运行环境参数不再起作用。
S103：基于所述运行环境参数启动一应用程序。
本步骤实现所述应用程序的启动，所述应用程序的运行基于所述沙箱程序中预设的运行环境参数。所述沙箱程序中可预设保护域，也就是定义了哪些应用程序是在所述沙箱程序中关联的，当所述沙箱程序运行后，在保护域内关联的应用程序运行时会按照所述沙箱程序的预设运行环境参数运行。所述应用程序的启动可以是接收用户的操作启动，例如用户对应用程序图标执行触摸操作打开应用程序。需要注意的是，所述应用程序与所述沙箱程序处于不同进程，但会继承沙箱应用的运行时环境，从外部看起来，等同于 是所述应用程序运行在所述沙箱程序内部。所述应用程序与操作系统的交互通过所述沙箱程序实现，即所述应用程序获取的各类输入事件须经基于所述沙箱程序内定义的运行环境参数进行处理，操作系统内原有的相关运行环境参数对于所述应用程序而言是不可见的。除了所述沙箱程序内定义的运行环境参数，其他的运行环境参数仍按照操作系统内的配置支持所述应用程序运行。从两者的从属关系上来看，所述应用程序是沙箱程序的客户端进程，而所述沙箱程序则是所述应用程序的宿主进程，所述应用程序会基于沙箱程序运行时的运行环境与沙箱程序进行通讯，沙箱程序会向所述应用程序暴露预设的API，提供相应功能，除了对输入事件处理以外，还可提供诸如获取系统状态，地理位置信息等功能。
作为所述应用程序启动方法的进一步改进，所述步骤S101中，所述运行环境参数包括根视图类的成员变量。本改进实施例对所述沙箱程序中自定义的运行环境参数进行了优选，即为所述根视图类的成员变量。所述根视图类为安卓操作系统应用层中的重要的类，英文为ViewRootImpl，其作用为对视图对象(View)进行填充，完成具体的视图对象的管理任务；根视图类还与窗口管理服务(WindowManagerService)进行沟通，管理要显示的界面。在本实施例中，通过对根视图类的成员变量进行自定义，实现对各输入事件进行处理，并将输入事件的结果反映在显示界面中。
进一步地，步骤S103之后，所述应用程序启动方法还包括：
S104：当所述应用程序接收一输入事件时，所述运行环境参数内的根视图类代替所述智能终端操作系统中的根视图类对所述输入事件进行识别并上报。
本改进实施例在所述运行环境参数包括根视图类的成员变量的基础上，实现了步骤S104。当所述智能终端触摸屏或其他输入设备接收了输入操作，所述智能终端的底层驱动识别所述输入操作并形成输入事件，再将所述输入事件逐层上报。本步骤实现对输入事件的处理过程，当所述应用程序监听到有输入事件发生时，所述应用程序根据所述沙箱程序提供的根视图类对所述输入事件进行识别，并上报给其他功能程序模块进行处理。所述沙箱程序的安全策略可以对输入事件发生时进行的运行环境参数的获取路径进行定义，以实现对所述根视图类的替换。而现有技术中，若没有运行沙箱程序，所述应用程序会根据操作系统默认的运行环境对所述输入事件进行处理，特别是对于不同的输入事件可能无法有效识别，仅能识别同一类型的输入事件，例如触摸屏输入事件。
作为所述应用程序启动方法的进一步改进，所述步骤S101中，所述输入事件包括与所述智能终端连接的外部输入设备对应的外部输入事件及智能终端触摸屏对应的触摸输入事件。本改进实施例对所述输入事件的种类作了进一步限定。用户在使用所述智能终 端运行需要大量复杂操作的应用程序时，例如玩游戏，仅通过智能终端触摸屏的输入操作难以满足交互需求，还需通过外部输入设备，例如游戏手柄与所述智能终端通信连接后进行辅助输入操作。现有技术中的智能终端操作系统对于所述外部输入设备接收的输入操作产生一外部输入事件，对于智能终端触摸屏接收的输入操作产生一触摸输入事件，然而操作系统的应用层无法对上述两种输入事件进行识别并区分处理，导致了两种输入事件无法并存，用户只能选择一种输入操作。本实施例中所述沙箱程序监听从所述操作系统框架层的接口上报的输入事件，并通过自定义的根视图类对不同的输入事件进行识别及处理，使得所述应用程序(例如游戏程序)具备对触摸屏操作和外部设备输入操作的识别能力，用户能够同时进行两种输入操作，丰富了输入操作方式，提升了体验效果。
作为所述应用程序启动方法的进一步改进，所述步骤S101中，于所述智能终端操作系统的应用层预设所述沙箱程序。所述沙箱程序工作于所述操作系统的应用层，其涉及的运行环境参数也主要为应用层的类或方法，工作时从所述操作系统框架层获取事件，无需对框架层本身进行修改。这样以来，即便操作系统进行了升级，也只需将沙箱程序在应用层进行移植，不涉及其他层的代码修改，减少了移植工作量。同时，由于所述应用程序直接与沙箱程序交互而非与操作系统交互，所述沙箱程序起到了屏障的作用，能够保障数据的安全性，防止数据泄露[与之前的情况一样，这边能否强调一下“同时可以方便地应用到不同的安卓系统(ROM)平台”]；同时，该沙箱程序及应用程序可以方便地应用到不同的安卓操作系统(ROM)平台，具有较好的通用性。
参阅图4，为符合本发明一优选实施例中应用程序启动方法的操作系统框图。图4展示了安卓(Android)操作系统下的各层，包括应用层(Application)、框架层(Framework)、本地运行库层(Android Native)及驱动层(Android Driver)，各层仅展示了与本发明相关的各模块。其中，驱动层包括了触摸屏驱动程序以及外部输入设备驱动程序，用于识别触摸屏及外部输入设备接收的输入操作，并形成输入事件。所述本地运行库层包括了输入管理服务本地运行库(InputManagerService Native)，为输入事件的处理提供本地支持。框架层包括了输入管理服务(InputManagerService)和视图类(View)，输入管理服务对输入事件进行管理，并上报给应用层，视图类则控制显示界面的显示。本发明涉及的沙箱程序及应用程序均在应用层，原本安装于操作系统内的应用程序在所述沙箱程序的基础上运行后变为应用程序’，所述应用程序’基于所述沙箱程序提供的运行环境运行，从框架层上报的输入事件经过所述沙箱程序后再上报至所述应用程序’。通过修改沙箱程序内部的运行环境，实现了输入事件的客制化需求，从而使得从沙箱内部启动的应用程序’获取客制化的能力，并为应用程序提供更多的扩展性和安全性。

-运行模块12
所述运行模块12与所述预设模块11连接，运行所述沙箱程序。所述运行模块12可以是开发环境下的运行指令；也可以将在应用层的用户交互操作与所述沙箱程序进行关联，当有用户交互操作(例如打开文件夹)时，运行所述沙箱程序。所述沙箱程序运行后，启动对所述输入事件的相关接口的监听，以便对输入事件的处理进行劫持，所述操作系统内原有的运行环境参数不再起作用。
