为了便于理解，本申请以下实施例将以具有图1和图2所示结构的电子设备为例，结合附图和应用场景，对本申请实施例提供的安装应用的方法进行具体阐述。
在描述本申请实施例的安装应用的方法之前，首先对本申请实施例中的术语做简单的介绍。
1、Android应用程序包(android application package，APK)：是Android操作系统使用的一种应用程序包文件格式，用于分发和安装移动应用及中间件。一个Android应用程序的代码想要在Android设备上运行，必须先进行编译，然后被打包成为一个被Android系统所能识别的文件才可以被运行，而这种能被Android系统识别并运行的文件格式便是“APK”。APK由xml、资源文件、dex(二进制字节码)文件组合而成。
2、阻塞调用：调用结果返回之前，当前线程会被挂起。
3、dexopt线程：用于执行dexopt任务，dexopt是对dex文件进行验证和优化的过程，生成可执行的odex文件。该过程可以提升应用启动和组件加载性能。
4、dex2oat线程：用于执行dex2oat工作任务，dex2oat是对APK文件进行优化，生成oat文件的过程。oat文件是一种Android私有elf文件格式，它不仅包含有从dex文件翻译而来的本地机器指令，还包含有原来的dex文件内容。对于APK来说，oat文件实际上是对odex文件的包装，即oat＝odex。
5、dex2oat工作任务队列管理线程：用于管理dex2oat工作任务队列，用于将dex2oat工作任务从dex2oat工作任务队列中取出。
图3是本申请实施例提供的一组图形用户界面(graphical user interface，GUI)的示意图。本申请实施例以在用户使用手机安装多个应用为例。其中，从图3中的(a)至(d)示出了用户一次性安装多个应用的过程。
参见图3中的(a)，该GUI为手机的桌面200，当手机检测到用户点击桌面200上的应用市场的图标210的操作后，可以显示如图3中的(b)所示的GUI。
参见图3中的(b)，该GUI显示的是应用市场的界面，用户可以在该应用市场中下载需要的各种应用，例如，用户一次下载多个应用，当手机检测到用户依次点击下载控件220、230、240时，即开始下载应用，可以显示如图3中的(c)所示的GUI。
参见图3中的(c)，手机可以在该界面上显示当前下载的多个应用的进度。
参见图3中的(d)，当该多个应用下载安装完成时，可以在手机的桌面220上显示该多个应用的图标。
图4是本申请实施例提供的一种安装应用的流程示意图。以基于安卓(Android)系统的电子装置为例，电子装置通过软件包安装(package installer)接口来安装应用。如图4所示，该步骤包括步骤101至步骤107。
步骤101，应用程序层创建任务。
其中，应用安装方通过软件包安装任务(package installer session，PIS)的方式创建任务。
步骤102，将任务提交到应用框架层中的PMS中，由PMS进行应用的安装。
步骤103，PMS安装应用。
其中，PMS安装应用时会从应用的下载目录中将应用的APK文件拷贝到系统目录中，并扫描该APK文件，通过扫描过程对该APK文件进行解析，以获取应用的组件、配置文件等信息。
步骤104，PMS调用系统层的installd接口执行dexopt，以对APK文件进行优化。
这个过程PMS阻塞调用installd接口。
步骤105，installd调用dex2oat线程。
其中，installd在执行dexopt时，通过内部调用dex2oat线程对APK文件进行二进制优化，以提升应用启动速度和组件加载性能。
步骤106，installd向PMS发送dex2oat线程执行结束的消息。
步骤107，PMS判断dexopt执行完成，则向应用安装方发送App安装完成的消息。
上述应用安装过程中，对于单个的应用安装，安装过程需要阻塞等待dex2oat优化过程，而dex2oat优化过程一般耗费时间较长，例如，在电子设备上安装典型应用微信(大小约为120MB)，调试版本的安装时间总共需要14s，其中dex2oat优化过程耗时约为7s，耗时占比约为整个应用安装耗时的一半。
图5是本申请实施例提供的一种PMS内部安装应用的时序流程示意图。如图5所示，该流程可以包括步骤201至步骤206。
201，PMS开始安装App1。
其中，PMS在开始安装App1时，持有mInstallLock锁，该mInstallLock锁为一种安装锁定保护文件，在当前应用安装未完成时，该安装锁定保护文件阻止其他应用安装。
202，PMS提交dexopt1任务。
其中，PMS向软件包dex优化器提交dexopt1任务，对App1的APK文件进行优化。
203，软件包dex优化器向installd发送dexopt1任务。
其中，该过程再次持有mInstallLock锁，在当前dexopt任务未完成时，该安装锁定保护文件阻止其他dexopt任务进行。
204，installd内部调用dex2oat线程执行dex2oat工作任务，对APK文件进行二进制优化。
205，dex2oat工作任务执行完成之后，installd向PMS发送App1安装完成的消息。
206，PMS在接收到App1安装完成的消息之后，向应用安装方发送该消息。
207，PMS开始进行App2的安装。
应理解，dex2oat工作任务执行结束后，mInstallLock锁会依次返回释放，在此期间，该安装应用阻塞等待，对于其他应用的安装请求无法执行。
因此，批量应用安装过程中，由于mInstallLock锁的存在，多个应用的安装和dex2oat工作任务是依次串行进行的，导致的结果是多个应用安装过程缓慢，用户体验感较差。因此，需要一种快速安装应用的方法，以提升用户体验。
应理解，本申请实施例中PMS拷贝和扫描APK文件的过程可以称为“上层”或“上层安装”，而dexopt或dex2oat的优化过程可以称为“底层”或“底层优化”。
如前文所述，电子设备在批量安装App时，多个App的上层安装过程和底层优化过程是依次串行进行的，导致多个App安装过程缓慢，用户体验感较差。
本申请提供一种安装应用的方法，在电子设备批量安装App时，将dex2oat工作任务的执行过程即App的底层优化过程从整个安装过程中拆解开来，做到App上层安装与App底层优化并行处理，从而加快了安装多个App时的安装速度，提升用户体验。
图6是本申请实施例提供的另一种PMS内部安装应用的时序流程示意图。如图6所示，该流程可以包括步骤201a至步骤206a。
201a，PMS开始安装App1。
202a，PMS将App1的dex2oat工作任务提交给优化器。
具体地，PMS将dex2oat工作任务提交到dex2oat工作任务队列中，由dex2oat工作任务队列管理线程管理该队列。
203a，PMS向应用安装方发送App1安装完成的消息。
应理解，该步骤202a与203a可以是同时进行的。
204a，PMS开始安装App2。
204b，优化器调用installd接口。
具体地，dex2oat工作任务队列管理线程用于将dex2oat工作任务从队列中取出。
205b，将该App1对应的dex2oat工作任务取出后，installd接口内部调用dex2oat线程执行该dex2oat工作任务。
应理解，步骤204b和步骤205b与步骤204a是并行进行的，步骤204b和步骤205b的执行并不会影响步骤204a的进行。
205a，PMS将App2的dex2oat工作任务提交给优化器。
206a，PMS向应用安装方发送App2安装完成的消息。
206b，在步骤205b执行结束之后，dex2oat工作任务管理线程会将App2对应的dex2oat工作任务从队列中取出，并调用installd接口。
207b，installd接口内部调用dex2oat线程执行该App2对应的dex2oat工作任务。
同样的，该步骤207b和步骤208b并不会影响下一个应用的安装。
本申请实施例中，PMS上层安装应用与应用的底层优化过程并行进行，相比于现有的串行安装过程，该技术方案可以提升批量安装应用时的安装速度，提升了用户体验。
图7是本申请实施例提供的一种安装应用的方法流程图。如图7所示，该方法可以包括步骤301至步骤305。
301，用户安装应用。
例如，用户在应用市场下载安装多个应用，或者使用克隆备份恢复多个应用。
302，拷贝APK文件。
应用安装方拷贝APK文件，以便于后续安装。
303，扫描APK文件。
其中，PMS扫描APK文件用于对APK文件进行解析，以获取应用的组件、配置文件等信息。
304，提交dex2oat工作任务。
其中，PMS调用installd接口执行dexopt优化，而installd内部调用dex2oat线程执行dex2oat优化过程，以对APK文件进行优化。
应理解，在电子设备批量安装应用的过程中，每个应用对应一个dex2oat工作任务。电子设备可以按照安装应用的顺序将应用对应的dex2oat工作任务组成一个队列，例如，电子设备依次安装App1，App2，App3，其各自对应的dex2oat工作任务分别为dex2oat1，dex2oat2，dex2oat3，则该dex2oat工作任务队列为dex2oat1，dex2oat2，dex2oat3。应用安装过程中，通过后台dex2oat工作任务队列管理线程，将该dex2oat工作任务从任务队列中依次取出，installd内部调用dex2oat线程执行dex2oat优化过程，不让其阻碍安装流程的执行，该过程将dex2oat工作任务执行的过程从整个应用安装的过程中拆解出来，将应用安装和dex2oat执行过程做并行处理，从而可以快速安装批量应用。
具体地，该步骤304可以包括步骤3041至步骤3046。
3041，启动后台dex2oat工作任务队列管理线程。
其中，该dex2oat工作任务队列管理线程用于管理dex2oat工作任务队列，将dex2oat工作任务依次从dex2oat工作任务队列中取出。
3042，等待dex2oat工作任务队列。
例如，电子设备依次安装App1，App2，App3，则该dex2oat工作任务为dex2oat1、dex2oat2、dex2oat3。
3043，若dex2oat工作任务空转超时，则结束该dex2oat工作任务队列管理线程。
其中，空转超时可以理解为dex2oat工作任务队列中没有任务执行的时间大于预设值，即可以认为该dex2oat工作任务队列中的dex2oat工作任务已全部执行结束，此时系统停止该工作任务队列管理线程，有利于降低电子设备的功耗。
3044，若dex2oat非空转，则获取dex2oat工作任务。
3045，执行dex2oat工作任务。
installd通过调用dex2oat线程执行dex2oat工作任务，以对应用的APK文件进行二进制优化。
3046，dex2oat工作任务执行结束。
其中，该dex2oat线程将dex文件编译成oat文件格式后，即该应用的dex2oat工作任务执行结束。
应理解，上述过程是一个应用的dex2oat工作任务的执行过程，该应用的dex2oat工作任务执行完成后，下一个应用的dex2oat工作任务的执行过程和上述步骤3042至3046 相同，不再赘述。
还应理解，该安装应用的顺序可以是电子设备下载应用完成的顺序，也可以是按照预设的优先级的顺序，本申请实施例对此不做具体限定。
305，安装应用完成。
应理解，在步骤305中，一旦步骤304提交了该应用对应的dex2oat工作任务，则可以认为该应用安装完成，即可以进行下一个应用的安装，而其对应的dex2oat工作任务转为后台执行。此时，PMS会向应用安装方发送该应用安装完成的广播消息。
例如，当前正在安装的应用为App1，在步骤304中提交了App1对应的dex2oat1后，则可以认为该App1安装完成，可以进行App2的安装，而在安装App2的同时，后台执行dex2oat1。
基于上述技术方案，在电子设备上批量安装应用时，可以将应用对应的dex2oat工作任务从安装过程中拆解出来，做到上层安装应用和底层dex2oat优化过程并行处理，从而可以加快批量应用的安装速度，提升用户体验。
图8是本申请实施例提供的一种安装应用的时序示意图。如图8所示，原技术方案中，电子设备批量安装应用时，多个应用是依次串行安装。例如，在安装App2之前，必须等待App1的dex2oat工作任务执行完毕，同样的，在安装App3之前，必须等待App2的dex2oat工作任务执行完毕。因此，导致批量应用安装缓慢，影响用户体验。
在本申请实施例中，如图8所示，响应于用户触发的安装应用程序的操作，拷贝和扫描第一应用程序对应的APK1(即上层安装App1)，在拷贝并扫描APK1之后的第一时间段t1内，拷贝和扫描第二应用程序对应的APK2(即上层安装App2)，在拷贝和扫描第一应用程序对应的APK1之后的第二时间段内t2内，执行对第一应用程序的优化，即在时间t2内执行dex2oat1，其中，该第一时间段t1和第二时间段t2至少部分重叠。
如图8所示，第一时间段t1和第二时间段t2的起始时间相同，此时dex2oat1和App2上层安装并行进行，从而可以提升应用的安装速度，提升用户体验。
在另一个示例中，该t1和t2的起始时间也可以不同，例如，t2的起始时间早于t1的起始时间，但t1和t2的时间段至少有部分重叠，也可以实现App2的上层安装和App1的底层优化的并行进行，从而可以提升多个应用的安装速度。
在一种可能的实现方式中，可以将该App1对应的第一优化任务即dex2oat任务加入第一任务队列中；由第一线程将该第一优化任务从第一任务队列中取出；并调用第一接口，该第一接口启动第二线程，以执行该第一优化任务。
例如，该第一任务队列为dex2oat任务队列，该第一线程为dex2oat任务队列管理线程，该第一接口为installd接口，该第二线程为dex2oat线程。
基于本申请实施例提供的安装应用的方法，在安装App1和App2时，相比于原安装应用方法，可以优化的时长为执行dex2oat1与执行dex2oat2所耗费时间的总和。
图9是本申请实施例提供的一种安装应用的时序示意图。本申请实施例中，批量安装应用时可能会出现的情况是：App1对应的dex2oat1的执行过程耗费时间较长，如图9中的(a)所示，上层App1安装完成，开始安装App2，同时底层开始对App1执行dex2oat1；App2上层安装完成，dex2oat2加入dex2oat工作任务队列，由于此时dex2oat1尚未执行完成，因此dex2oat2只能在队列中等待执行；此时，上层开始安装App3，App3上层安装完成后，dex2oat3加入dex2oat工作任务队列等待执行；上层开始安装App4，App4上层安 装完成后，dex2oat4加入dex2oat工作任务队列等待执行，此时dex2oat1依然尚未执行完成。因此，造成的结果是dex2oat工作任务队列中积压了较多的任务，而这些任务并未真正执行，如果此时电子设备出现异常情况(如，关机或重启等)，那么可能会出现有些App没有执行其对应的dex2oat的情况，那么当用户启用该应用时，将会以普通模式启动。
应理解，对App进行dex2oat优化，可以提升App的启动速度和组件加载性能，普通模式即不对App进行优化，可能出现的情况是该App的启动速度较慢。
针对可能出现的上述情形，本申请实施例提供一种方法，可以控制dex2oat工作任务队列中积压的任务数量。如图9中的(b)所示，该方法可以包括如下步骤：
(1)App1上层安装完成，在App1上层安装完成之后的第一时间段t1内上层安装App2，在App1上层安装完成之后的第二时间段t2内，执行对App1的优化。
例如，该第一时间段t1和第二时间段t2的起始时间相同，即在上层安装App2的同时底层开始对App1执行dex2oat1。
(2)在App1上层安装完成之后的第三时间段t3内，上层安装App3。
例如，App2上层安装完成，dex2oat1尚未执行完成，此时，将App2对应的dex2oat2加入等待队列中，同时上层开始安装App3。
(3)在App1上层安装完成之后的第四时间段t4内，执行对App2的优化。
例如，将App2对应的dex2oat2加入等待队列中，在第四时间段t4内执行。
具体地，由dex2oat工作任务队列管理线程(即第一线程)将该dex2oat2从队列中取出，PMS调用installd接口执行，而installd内部启动dex2oat线程(即第三线程)执行该dex2oat2。
(4)在App1上层安装完成之后的第五时间段t5内，上层安装App4，其中，在该第二时间段t2的时长大于所述第一时间段t1和所述第三时间段t3的时长之和时，拷贝并扫描第四应用程序包的起始时刻(即t5的起始时刻)晚于或等于对该第二应用程序执行优化的起始时刻(即t4的时刻)。
其中，当该第二时间段t2的时长大于第一时间段t1和第三时间段t3的时长之和时，意味着App1的底层优化任务耗费的时间较长，如果不加控制，底层的dex2oat工作任务队列中可能会积压多个dex2oat工作任务，此时PMS不向应用安装方发送该App3安装完成的广播，而是等待底层dex2oat1执行完成。在底层dex2oat1执行完成的同时，开始执行dex2oat2，此时App3对应的dex2oat3加入dex2oat等待队列，则dex2oat工作任务队列中等待执行的是dex2oat3，此时PMS向应用安装方发送该App3安装完成的消息，则上层开始继续安装App4，此时，该对App2执行优化的起始时刻等于对App4进行拷贝和扫描的起始时刻，即上层安装App4和底层执行dex2oat2是同时进行的。
应理解，后续更多应用的安装可以参考上述安装过程，不再赘述。
应理解，上述过程以dex2oat工作任务队列中积压一个dex2oat工作任务为例进行说明，但本申请实施例不局限于此，本申请实施例中dex2oat工作任务队列中积压的dex2oat工作任务数量也可以是两个、三个或更多个。
基于上述技术方案，在批量安装应用时，当某个应用的dex2oat执行过程耗费时间较长时，该方案可以避免dex2oat工作任务队列中积压过多的dex2oat工作任务。
图10是本申请实施例提供的一种安装应用的方法流程示意图。该方法可以包括步骤401至步骤408。
401，用户安装应用。
402，拷贝APK文件。
403，扫描APK文件。
应理解，上述步骤401至403可以参考前文所述，为了简洁，不再赘述。
404，提交dex2oat工作任务。
其中，PMS调用installd接口执行dexopt优化，而installd内部调用dex2oat线程来执行dex2oat优化过程。
405，并行化dex2oat工作任务。
如前文所述，应用本申请实施例中的安装应用的方法，上层安装App与底层执行dex2oat工作任务并行化处理，以加快应用的安装速度。
406，若dex2oat工作任务等待队列不为空，则阻塞等待队列清空。
应理解，该dex2oat工作任务等待队列表示除当前正在执行的dex2oat工作任务之外，等待执行dex2oat工作任务的队列。
在安装应用过程中，上层安装App与底层dex2oat工作任务并行处理时，若当前dex2oat工作任务等待队列不为空，则意味着当前dex2oat工作任务尚未执行完成，则此时，PMS阻塞等待该dex2oat工作任务执行完成后，再通知应用安装方该应用安装完成。
例如，参考图9中的(b)，上层安装App3，在PMS提交dex2oat3时，当前dex2oat1尚未执行完成，此时，dex2oat工作任务队列中还有dex2oat2等待执行，那么，PMS不向应用安装方发送App3安装完成的消息，而是阻塞等待该dex2oat1执行完成。dex2oat1执行完成之后，开始执行dex2oat2，则此时等待队列为空。
407，若dex2oat工作任务等待队列为空，则提交dex2oat工作任务。
若dex2oat工作任务队列为空，则意味着该dex2oat工作任务队列中等待执行的dex2oat工作任务为空，则此时可以向dex2oat工作任务队列提交该应用的dex2oat工作任务，即将该应用对应的dex2oat工作任务加入dex2oat工作任务等待队列中。
在一个示例中，步骤406中dex2oat工作任务等待队列不为空，PMS阻塞等待队列清空之后，PMS提交该应用的dex2oat工作任务到任务队列中。例如，参考图9中的(b)，dex2oat1执行完成之后，开始执行dex2oat2，此时dex2oat等待队列为空，则PMS向应用安装方发送App3安装完成的广播，同时App3对应的dex2oat3加入dex2oat等待队列中等待执行。
在另一个示例中，上层安装App3，底层正在执行dex2oat2，此时，dex2oat工作队列中并未有等待执行的dex2oat工作任务，则此时将该dex2oat3加入该dex2oat工作任务队列中等待执行。
408，安装应用完成。
将当前安装App的dex2oat工作任务提交到dex2oat工作任务队列中后，PMS向应用安装方发送该App安装完成的广播。
应理解，此时，尽管PMS向应用安装方发送了该App安装完成的广播，但该App对应的dex2oat工作任务仍在后台执行或等待执行。
基于上述技术方案，在批量安装应用时，该方案可以避免dex2oat工作任务队列中积压过多的dex2oat工作任务。
在批量应用安装过程中，应用的dex2oat工作任务是在电子设备的本地系统中执行， 由于该dex2oat执行过程是一个高计算量的过程，因此会有较多的功耗，导致电子设备短时间内出现温度上升，从而可能会影响电子设备的稳定性。因此，本申请实施例提供一种温度控制策略方法来改善上述问题。
图11是本申请实施例提供的一种安装应用时温控策略的方法的时序流程示意图。如图11所示，电子设备上层安装完App1，底层开始执行dex2oat1，同时上层开始安装App2，在准备提交dex2oat2时，即T1时刻，监测电子设备的温度，该温度可以是电子设备的整机温度，也可以是电子设备的中央处理器(center processing unit，CPU)的温度。
例如，可以预先设置该温度的阈值范围，当该温度大于第一阈值时，即认为该电子设备的温度异常，当该温度小于或等于第一阈值时，即认为该电子设备的温度正常，例如，该第一阈值可以是35度至40度之间的任意值。
若T1时刻监测到该电子设备的温度异常，再确定第一执行时长(即第四时间段)，该第一执行时长用于表示该电子设备连续执行dex2oat工作任务的时长，该第一执行时长可以用于判断dex2oat工作任务是否已经长时间执行，若dex2oat工作任务已经长时间执行，则PMS不向应用安装方发送App2安装完成的广播，并触发停止dex2oat工作任务即暂停dex2oat工作任务队列管理线程，使其休息第一预设时长，即在第一预设时长内暂停dex2oat工作任务的调度，也就是说，在该第一预设时长之后，再拷贝并扫描App3。值得注意的是，并不是马上停止当前dex2oat工作任务的执行过程，而是让App2的dex2oat2执行完成才触发停止dex2oat工作任务，如图11中的T2时刻，因为App的扫描和dex2oat优化过程是一个安装过程，所以尽量使其不分离，避免出现稳定性不足的问题。
可选地，当T1时刻检测到电子设备的温度异常时，就可以触发停止dex2oat工作任务，即使dex2oat工作任务队列管理线程暂停第一预设时长，同样的，等待App2的dex2oat2执行完成才触发停止dex2oat工作任务。
应理解，本申请实施例中的温度监控可以通过温度传感器来实现，也可以通过其他具有温度监控功能的传感器来实现，本申请实施例对此不做具体限定。
应理解，本申请实施例中可以通过统计当前dex2oat优化过程的执行时间来判断其是否已经长时间执行，例如，当前dex2oat优化过程的执行时间大于预设的值，可以认为其已经长时间执行，下文将结合具体实施例描述判断当前dex2oat优化过程是否已经长时间执行的过程，此处暂不详述。
T2时刻，触发停止dex2oat工作任务队列管理线程，使其休息一段时间至T3时刻，该休息的时间间隔可以是预先设定的时长，例如5s或10s或其他值。
T3时刻，dex2oat工作任务已经暂停了一段时间t，PMS向应用安装方发送App2安装结束的广播，并开始安装App3。
T4时刻，上层安装App3结束，底层开始执行dex2oat3。
可以看出，从T2时刻触发停止dex2oat工作任务开始，到T4时刻开始执行dex2oat3，实际上dex2oat工作任务的休息时长为T2至T4，从而可以有效降低电子设备在批量安装应用过程中短时间内出现的发热问题。
应理解，后续更多应用的安装可以参照上述T1至T4时刻，为了简洁，不再赘述。
下面结合图12介绍本申请实施例中统计dex2oat工作任务执行时长的方法。
图12是本申请实施例提供的一种统计dex2oat工作任务工作时间的流程示意图。如图12所示，该方法可以包括步骤501至步骤509。
步骤501，用户安装应用。
步骤502，提交dex2oat工作任务。
步骤503，dex2oat工作任务开始执行，记录时间T1。
步骤504，dex2oat工作任务执行完成，记录时间T2。
步骤505，记录本次dex2oat执行时间：dT＝T2-T1。
步骤506，计算本次dex2oat工作任务与上次dex2oat工作任务的时间间隔：AT＝T1-LT2。
其中，AT表示本次dex2oat工作任务与上次dex2oat工作任务的时间间隔，LT2表示上次dex2oat工作任务执行完成的时间。
步骤507，若AT≤MIN_INTER，则dex2oat的工作时间WT为本次dex2oat的工作时长与上次dex2oat的工作时长之和。
其中，WT表示dex2oat的工作时间，MIN_INTER表示最小时间间隔。应理解，该最小时间间隔可以是预先设置的值，例如，该最小时间间隔可以为20s或30s或其他值。
若本次dex2oat工作任务与上次dex2oat工作任务的时间间隔AT小于或等于设定的dex2oat的最小时间间隔MIN_INTER，则累计dex2oat工作时间。
示例性地，如图11所示，在拷贝并扫描第一应用程序App1之前的第五时间段t5内，执行对第四应用程序App0的底层优化dex2oat0，若T1时刻，在执行dex2oat0的第五时间段t5与执行dex2oat1的第二时间段的间隔小于或等于最小时间间隔(即第三预设时长)，则dex2oat的工作时间WT(即第四时间段)为第五时间段t5与第二时间段t2的时长之和。
步骤508，若AT>MIN_INTER，则dex2oat的工作时间：WT＝dT。
若本次dex2oat工作任务与上次dex2oat工作任务的时间间隔AT大于设定的dex2oat的最小时间间隔MIN_INTER，则将本次dex2oat的执行时间dT作为dex2oat的工作时间。
示例性地，如图11所示的T1时刻，若第五时间段t5与第二时间段t2之间的间隔大于第三预设时长，则dex2oat的工作时间WT(第四时间段)为dex2oat1的执行时间即第一时间段t1。
步骤509，LT2＝T2。
在下一个dex2oat工作任务开始时，将该当前dex2oat工作任务执行完成的时间作为LT2。
应理解，下一个或多个dex2oat工作任务的工作时间的统计可以参考上述步骤，为了简洁，不再赘述。
下面结合图13介绍本申请实施例的温控策略的优化调控的方法。
图13是本申请实施例提供的一种温控策略的优化调控流程示意图。如图13所示，该方法可以包括步骤601至步骤606。
步骤601，安装App2。
应理解，在该步骤601之前，上层已经安装完App1，该步骤中上层安装App2和底层执行dex2oat工作任务是并行进行的。
步骤602，提交dex2oat工作任务。
步骤603，系统根据温度监测结果，读取温度信息Temp。
其中，系统可以根据温度传感器来监测电子设备的温度，该温度可以是电子设备的整机温度，也可以是CPU的温度。
步骤604，根据步骤603中温度的监测结果，若此时电子设备的温度Temp>MIN_TEMP，且dex2oat工作时间WT>MAX_WT，则触发dex2oat工作任务暂停。
其中，MIN_TEMP表示门限温度，该门限温度用于判断电子设备安装应用时温度是否异常的临界温度，MAX_WT用于表示最长工作时间。该MIN_TEMP的值和MAX_WT的值可以通过系统预设来实现，如前文所述，该MIN_TEMP可以为35度至40度之间的任意值，该MAX_WT可以为20s至30s之间的任意值。
应理解，本申请实施例中的WT可以通过图10中的统计dex2oat工作任务的工作时间的方法获取。
其中，该步骤604中虽然触发了dex2oat工作任务停止，但是为了避免应用安装过程中出现的稳定性问题，并不是马上停止当前正在执行的dex2oat工作任务，如前文所述，而是让App2的dex2oat2执行完成才让dex2oat工作任务停止。
步骤605，dex2oat2执行完成。
其中，dex2oat2执行完成后，dex2oat工作任务会停止一段时间，以避免电子设备由于温度过高，而带来稳定性不足的问题。
步骤606，WT清零处理。
其中，触发dex2oat工作任务停止时，将dex2oat的工作时间WT置零，以便于下一个周期中dex2oat的工作时间的统计。
基于上述技术方法，当批量安装应用时，由于dex2oat工作任务执行过程中会有较多的功耗，本申请实施例中的温控策略的优化方法可以避免电子设备由于温度过高而带来稳定性不足的问题。
图14是本申请实施例提供的一种安装应用的方法的示例性流程图。如图14所示，该方法可以包括步骤710至步骤740。
710，电子设备检测到用户触发安装应用程序的操作。
示例性的，用户在应用市场中一次性下载安装多个应用，或者用户使用电子设备克隆恢复多个应用，从一个设备克隆多个应用到另一个设备等。
720，响应于该操作，拷贝并扫描第一应用程序包，该第一应用程序包为该第一应用程序对应的应用程序包。
其中，电子设备响应于用户的操作，拷贝并扫描第一应用程序包，即电子设备上层安装第一应用。
730，在该拷贝并扫描第一应用程序包后的第一时间段内，拷贝并扫描第二应用程序包，该第二应用程序包为第二应用程序对应的应用程序包；
其中，该第一时间段可以在电子设备扫描并拷贝第一应用程序包之后立即开始，也可以在电子设备扫描并拷贝第一应用程序包之后间隔一段时间开始。
740，在该拷贝并扫描第一应用程序包后的第二时间段内，执行对该第一应用程序的优化；其中，该第一时间段和该第二时间段至少部分重叠。
可选地，该第一时间段和第二时间段的起始时间相同，即第二应用的上层安装和第一应用的底层优化是同时进行的。
可选地，该第一时间段和第二时间的起始时间不相同，例如，第一时间段的起始时间晚于第二时间段的起始时间，此时，电子设备上层安装第一应用程序和第二应用程序会间隔一段时间，有利于减轻电子设备出现的发热现象。
上述实施例中以电子设备安装两个应用程序为例进行说明，但这不应对本申请造成任何限定，应理解，更多个应用的安装过程可以参考上述过程。
