Description

用于安卓应用主进程唤醒的方法、存储介质、设备及系统 技术领域
本发明涉及移动软件领域，具体涉及一种用于安卓应用主进程唤醒的方法、存储介质、设备及系统。
背景技术
在日益激烈的移动互联网领域，提高APP(Application，应用程序)的活跃率是各大APP开发商颇为关注的事情，其中，APP的启动速度更是直接关系到用户对于APP的使用体验，如APP启动速度过慢则会直接减少用户对当前APP使用友善度，严重的甚至会直接导致用户卸载当前APP，进而大幅降低APP的安装量，进而影响APP的活跃率，因此提高APP的启动速度是APP开发人员当前迫切需要解决的难题。
当前，对于APP启动速度的提升，较常采用的做法是维持应用的主进程在后台长期运行，从而可以在不重复启动应用的情况下瞬间将应用置于前台，从而提高应用程序的启动速度。对于Android操作系统，当应用程序的主进程被操作系统关闭后，进行唤醒的方式有多种，较为常见的方案有如下三种：
(1)将应用程序加入启动白名单，当应用程序的主进程被关闭或异常退出时，操作系统随即采用唤醒机制，对应用程序的主进程进行唤醒。该方案的优点是主进程由操作系统唤醒，主进程唤醒成功率高，缺点是需要应用程序的厂商和操作系统厂商或手机厂商进行合作，方可将应用程序加入到启动白名单中。
(2)多进程保鲜机制，一个应用程序在运行时由多个进程组成：一个主进程和多个后台进程，当主进程被关闭或异常退出时，其它任意后台进程检测到主进程被关闭的警报后，随即开展主进程唤醒。该方案的优点是技术实现难度低，且无需做系统层面的处理，如应用程序白名单的添加，但缺点是一旦后台程序一并被杀死，唤醒机制则难以为继。
(3)关联启动机制，即当终端(运行Android操作系统的设备)中安装有多个集成了相同唤醒SDK(Software Development Kit，软件开发工具包)的应用程序，当其中一个应用程序处于运行状态，其后台进程则会随即开展搜索当前设备与其相似集成唤醒SDK的应用，搜索完成后随机进行应用唤醒，但随着Android操作系统版本的升级以及对后台权限的管制加强，关联启动机制在高版本的Android操作系统则无法展开，存在兼容性的问题。
发明内容
针对现有技术中存在的缺陷，本发明的目的在于提供一种用于安卓应用主进程唤醒的方法、存储介质、设备及系统，能够有效保证对应用程序主进程的唤醒。
为达到以上目的，本发明采取的技术方案是，包括：
S1：给应用程序新建一后台进程，通过新建的后台进程使得应用程序与服务端建立长连接，且后台进程运行的优先级和应用程序主进程的优先级相同，且后台进程包含用于监控应用程序主进程运行状态的监控服务，所述服务端为应用程序厂商推送服务的服务器；
S2：在应用程序与服务端间的长连接断开前，监控服务监控应用程序主进程的运行状态，若应用程序主进程的运行状态为结束运行状 态，则监控服务唤醒应用程序主进程，若应用程序主进程的运行状态为正常运行状态，则不做处理，在应用程序与服务端间的长连接断开后，服务端创建一通知消息并下发至运行应用程序的终端设备；
S3：终端设备的Android操作系统的系统服务接收服务端发送的通知消息，并对接收的通知消息的类型进行判断，若通知消息的类型为进程唤醒消息，则转到S4，若否，则结束；
S4：通过进程唤醒消息唤醒后台进程，并启动新建的后台进程的监控服务，监控服务判断应用程序主进程的运行状态，若应用程序主进程为结束运行状态，则新建的后台进程对应用程序的主进程进行唤醒，若否，则结束。
在上述技术方案的基础上，
所述应用程序与服务端间的长连接基于Socket通信；
所述应用程序与服务端间以应用程序的名称作为通信标识；
所述后台进程调用Android操作系统的本地服务建立应用程序与服务端间的长连接。
在上述技术方案的基础上，在应用程序与服务端间的长连接断开之前，后台进程对应用程序主进程的运行状态的判断，具体为：
后台进程每隔一预设时间间隔向应用程序主进程发送一条广播，应用程序主进程接受到广播后回馈一条包含有应用程序主进程自身运行状态信息的广播给后台进程，若后台进程在下一条广播发出前接收到应用程序主进程回馈的广播，则表示应用程序主进程为运行状态，反之，应用程序主进程为关闭状态。
在上述技术方案的基础上，所述后台进程通过轮训器向应用程序主进程发送广播。
在上述技术方案的基础上，若终端设备接收到的通知消息的类型 为进程唤醒消息，则Android操作系统通知栏对进程唤醒消息进行展示以供用户选择是否唤醒应用程序主进程，若用户选择是，则唤醒后台进程并唤醒应用程序主进程，若用户选择否，则结束。
本发明还提供一种存储介质，该存储介质上存储有计算机程序，所述计算机程序被处理器执行时实现上述所述的方法。
本发明还提供一种用于安卓应用主进程唤醒的设备，包括存储器和处理器，存储器上储存有在处理器上运行的计算机程序，所述处理器执行所述计算机程序时实现上述所述的方法。
本发明还提供一种用于安卓应用主进程唤醒的系统，包括：
创建模块，其用于新建一后台进程，通过新建的后台进程使得应用程序与服务端建立长连接，且后台进程运行的优先级和应用程序主进程的优先级相同，且后台进程包含用于监控应用程序主进程运行状态的监控服务，所述服务端为应用程序厂商推送服务的服务器；
判断模块，其用于判断应用程序与服务端间的长连接是否断开，在应用程序与服务端间的长连接断开前，监控服务监控应用程序主进程的运行状态，若应用程序主进程的运行状态为结束运行状态，则监控服务唤醒应用程序主进程，若应用程序主进程的运行状态为正常运行状态，则不做处理，在应用程序与服务端间的长连接断开后，则表示后台进程已结束运行，则服务端创建一通知消息并下发至运行应用程序的终端设备；
消息接收及进程唤醒模块，其用于接收服务端发送的通知消息，并对接收的通知消息的类型进行判断，若为非进程唤醒消息，则结束，若通知消息的类型为进程唤醒消息，则唤醒后台进程，并启动新建的后台进程的监控服务，同时监控服务判断应用程序主进程的运行状态，若应用程序主进程为结束运行状态，则新建的后台进程对应用程 序的主进程进行唤醒，若否，则结束。
在上述技术方案的基础上，所述应用程序与服务端间的长连接基于Socket通信；
所述应用程序与服务端间以应用程序的名称作为通信标识；
所述后台进程调用Android操作系统的本地服务建立应用程序与服务端间的长连接。
在上述技术方案的基础上，所述后台进程通过轮训器向应用程序主进程发送广播。
与现有技术相比，本发明的优点在于：通过在应用程序中新建一个后台进程，后台进程具有对应用程序主进程进行唤醒和运行状态判断的功能，在应用程序与服务端间的长连接断开前，新建的后台进程能对停止运行的应用程序的主进程进行唤醒，当应用程序与服务端间的长连接断开后，服务端发送消息对应用程序的主进程进行唤醒，采用多重唤醒保险机制，确保应用程序主进程被唤醒，有效避免了应用程序所有进程被关闭后，应用程序主进程无法被唤醒情况的出现，且服务端向运行应用程序的终端设备发送的进程唤醒消息，采用友好的交互方式，由用户自己决定是否对已停止运行的应用程序的主进程进行唤醒。
附图说明
图1为本发明实施例中一种用于安卓应用主进程唤醒的方法的流程图；
图2为本发明实施例中用于安卓应用主进程唤醒的设备的结构示意图。
具体实施方式
以下结合附图及实施例对本发明作进一步详细说明。
参见图1所示，本发明实施例提供一种用于安卓应用主进程唤醒的方法，用于对Android操作系统中应用程序的已关闭或休眠的主进程进行唤醒，从而提升应用程序的启动速度。
本发明实施例的用于安卓应用主进程唤醒的方法具体包括：
S1：给应用程序新建一后台进程，通过新建的后台进程使得应用程序与服务端建立长连接，且后台进程运行的优先级和应用程序主进程的优先级相同，且后台进程包含用于监控应用程序主进程运行状态的监控服务，服务端为应用程序厂商推送服务的服务器，服务端能够发送各种类型消息至Android操作系统中运行的应用程序。对于新建的后台进程的优先级，为了保持后台进程的长期鲜活性，因此需要将后台进程运行的优先级设置和应用程序主进程的优先级相同，即为最高优先级。
通过新建的后台进程，应用程序与服务端间建立长连接，长连接是指在一个连接上可以连续发送多个数据包，在连接保持期间，如果没有数据包发送，需要双方发链路检测包。对于应用程序与服务端间的长连接：应用程序与服务端间的长连接基于Socket(套接字)通信；应用程序与服务端间以应用程序的名称作为通信标识；后台进程调用Android操作系统的本地服务建立应用程序与服务端间的长连接。因此，当应用程序与服务端间的长连接建立后，即代表新建的后台进程被激活。
S2：在应用程序与服务端间的长连接断开前，监控服务监控应用程序主进程的运行状态，若应用程序主进程的运行状态为结束运行状态，则监控服务唤醒应用程序主进程，若应用程序主进程的运行状态为正常运行状态，则不做处理，在应用程序与服务端间的长连接断开 后，则服务端创建一通知消息并下发至运行应用程序的终端设备。因为应用程序与服务端间的长连接是由应用程序内新建的后台进程所建立的，因此当应用程序被关闭或停止运行时，应用程序的后台进程也有可能被终止，因此应用程序与服务端间的长连接是会出现断开的情况的。因此，在应用程序与服务端间的长连接断开前，对于结束运行的应用程序的主进程采用一种唤醒方式，在应用程序与服务端间的长连接断开后，采用后续的对应用程序主进程的另一种唤醒方式，双重保险，有效提高停止运行的应用程序主进程的唤醒率。对于关闭或停止运行的应用程序主进程的唤醒，新建的后台进程通过启动应用程序主进程的内部服务的方式来唤醒应用程序主进程。
新建的后台进程和应用程序主进程间的运行在本质上是相互不存在干扰的，因此，为了达到进程的间的状态同步，需要建立长期的进程间的通信机制，本发明实施例采用的是发送广播的方式来实现新建的后台进程和应用程序主进程间的状态同步。
同样的，在应用程序与服务端间的长连接断开之前，后台进程对应用程序主进程的运行状态的判断，具体为：
后台进程每隔一预设时间间隔向应用程序主进程发送一条广播，预设的时间间隔可以为30秒，应用程序主进程接受到广播后回馈一条包含有应用程序主进程自身运行状态信息的广播给后台进程，若后台进程在下一条广播发出前接收到应用程序主进程回馈的广播，则表示应用程序主进程为运行状态，反之，应用程序主进程为关闭状态。新建的后台进程通过轮训器向应用程序主进程发送广播，新建的后台进程发送给应用程序主进程的广播可以为空消息。
S3：终端设备的Android操作系统的系统服务接收服务端发送的通知消息，并对接收的通知消息的类型进行判断，若通知消息的类型 为进程唤醒消息，则转到S4，若否，则结束。因为应用程序与服务端间的长连接是由应用程序内建立的后台进程建立的，因此当应用程序与服务端间的长连接断开，则极有可能是因为应用程序结束运行而导致的，因此需要通过服务端向终端设备发送通知的方式来对应用程序主进程进行唤醒。本发明实施例中，终端设备为智能手机或平板电脑。
服务端发送给终端设备中应用程序的消息的类型存在多种形式，如常规类的通知消息等等，这里，当应用程序与服务端间的长连接断开后，服务端发送给终端设备的消息类型为进程唤醒消息，通过进程唤醒消息来达到对应用程序主进程唤醒的目的。对于服务端发送给终端设备常规类型消息，按照常规的处理，如启动APP、跳转指定页面等等，这里与本发明无关，本发明关注的是服务端发送给终端设备的进程唤醒消息，进程唤醒消息是本发明实施例定义的一种消息类型，其主要作用是为了实现后续的对应用程序主进程进行唤醒目的。例如，对于某直播软件的主进程的唤醒，进程唤醒消息的格式可以为：
{
"msg_id":"uu481201399440513912",//消息id
"msg_type":1001,                //消息类型，1001代表进程唤醒
"display_type":"notification",//展示形式
"body":{
"title":"斗鱼直播",
"ticker":"精彩直播尽在斗鱼直播",
"text":"null",
"after_click":"process_awaken",//点击的操作—唤醒
"url":"com.douyu.android.socket.process",//后台进程包名
"activity":"null",//只启动进程，不展示任何界面
"custom":"null",    //无任何其他参数
"play_vibrate":"false",//禁止震动
"play_sound":"false",    //禁止响铃
"play_lights":"false"//禁止开启灯光
},
}
同时，由于服务端发送给终端设备的消息，消息由终端设备中运行的Android操作系统的系统推送服务接收并处理，由于是系统推送服务，且操作系统中的系统推送服务会一直运行，除非终端设备关机，不然系统推送服务会一直处于运行状态，因此可以确保终端设备接受到服务端发送的进程唤醒消息。
进一步地，为提高应用程序厂商服务的人性化，还能够增添以下步骤，若终端设备接收到的通知消息的类型为进程唤醒消息，则Android操作系统通知栏对进程唤醒消息进行展示以供用户选择是否唤醒应用程序主进程，若用户选择是，则进行后续的唤醒后台进程并唤醒应用程序主进程的操作，若用户选择否，则结束，将应用程序的运行权交给用户。此时，对于应用程序主进程是否存活的判断，同样可以采用发送广播的方式对应用程序主进程的运行状态进行判断，发送广播的时间间隔可以自由设定。
S4：通过进程唤醒消息唤醒后台进程，并启动新建的后台进程的监控服务，监控服务判断应用程序主进程的运行状态，若应用程序主进程为结束运行状态，则新建的后台进程对应用程序的主进程进行唤醒，若否，则结束。
本发明的一种用于安卓应用主进程唤醒的方法的原理在于，通过在应用程序中新建一个后台进程，后台进程具有对应用程序主进程进 行唤醒和运行状态判断的功能，同时，后台进程建立基于Socket通信的应用程序与服务端间的长连接，实现服务端对应用程序主进程运行状态的监控，同时，在应用程序与服务端间的长连接断开前，新建的后台进程能对停止运行的应用程序的主进程进行唤醒，且当应用程序与服务端间的长连接断开后，服务端向运行应用程序的终端设备发送消息，对停止运行的应用程序的主进程进行唤醒，采用多重唤醒保险机制，实施方便，确保应用程序主进程的唤醒，有效避免了应用程序所有进程被关闭后，应用程序主进程无法被唤醒情况的出现，且应用程序厂商无需与终端设备厂商进行合作，也同时避免了应用程序进程唤醒时Android操作系统版本问题，同时，服务端向运行应用程序的终端设备发送的进程唤醒消息，采用友好的交互方式，由用户自己决定是否对已停止运行的应用程序的主进程进行唤醒。
另外，对应上述用于安卓应用主进程唤醒的方法，本发明还提供一种存储介质，存储介质上存储有计算机程序，计算机程序被处理器执行时实现上述各实施例所述的用于安卓应用主进程唤醒的方法的步骤。需要说明的是，所述存储介质包括U盘、移动硬盘、ROM(Read-Only Memory，只读存储器)、RAM(Random Access Memory，随机存取存储器)、磁碟或者光盘等各种可以存储程序代码的介质。
参见图2所示，对应上述用于安卓应用主进程唤醒的方法，本发明还提供一种用于安卓应用主进程唤醒的设备，包括存储器和处理器，存储器上储存有在处理器上运行的计算机程序，处理器执行计算机程序时实现上述各实施例的安卓应用主进程唤醒的方法。
本发明还提供一种基于上述安卓应用主进程唤醒的方法的安卓应用主进程唤醒的系统，包括创建模块、判断模块和消息接收及进程唤醒模块。
创建模块用于新建一后台进程，通过新建的后台进程使得应用程序与服务端建立长连接，且后台进程运行的优先级和应用程序主进程的优先级相同，且后台进程包含用于监控应用程序主进程运行状态的监控服务，所述服务端为应用程序厂商推送服务的服务器；判断模块用于判断应用程序与服务端间的长连接是否断开，在应用程序与服务端间的长连接断开前，监控服务监控应用程序主进程的运行状态，若应用程序主进程的运行状态为结束运行状态，则监控服务唤醒应用程序主进程，若应用程序主进程的运行状态为正常运行状态，则不做处理，在应用程序与服务端间的长连接断开后，则表示后台进程已结束运行，则服务端创建一通知消息并下发至运行应用程序的终端设备；
消息接收及进程唤醒模块用于接收服务端发送的通知消息，并对接收的通知消息的类型进行判断，若为非进程唤醒消息，则结束，若通知消息的类型为进程唤醒消息，则唤醒后台进程，并启动新建的后台进程的监控服务，同时监控服务判断应用程序主进程的运行状态，若应用程序主进程为结束运行状态，则新建的后台进程对应用程序的主进程进行唤醒，若否，则结束。
应用程序与服务端间的长连接基于Socket通信；应用程序与服务端间以应用程序的名称作为通信标识；后台进程调用Android操作系统的本地服务建立应用程序与服务端间的长连接。后台进程通过轮训器向应用程序主进程发送广播。
本发明的用于安卓应用主进程唤醒的系统的原理在于：创建模块通过在应用程序中新建一个后台进程，后台进程具有对应用程序主进程进行唤醒和运行状态判断的功能，同时，后台进程建立基于Socket通信的应用程序与服务端间的长连接，实现服务端对应用程序主进程运行状态的监控，同时判断模块对应用程序与服务端间的长连接是否 断开进行判断，在应用程序与服务端间的长连接断开前，新建的后台进程能对停止运行的应用程序的主进程进行唤醒，且当应用程序与服务端间的长连接断开后，服务端向运行应用程序的终端设备发送消息，对停止运行的应用程序的主进程进行唤醒，采用多重唤醒保险机制，实施方便，确保应用程序主进程的唤醒，有效避免了应用程序所有进程被关闭后，应用程序主进程无法被唤醒情况的出现。
本发明不局限于上述实施方式，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围之内。本说明书中未作详细描述的内容属于本领域专业技术人员公知的现有技术。
