1. Web Application Model


136

!3

• Web 应⽤用程序 – Using web based technologies (HTML/JS/CSS/etc.) – Accessing local device / platform resources – Can be installed on the device

• Web 运⾏行时 – Package management (installation, update, etc.) – Execution and lifecycle (launching, pause, resume, etc.) – Runtime security (API/network access, sandboxing, etc.) – Device and platform integration

什么是Web应⽤用程序和Web运⾏行时

Tizen web app ecosystem


136

!5

• Environment within which all web 应⽤用程序s run on Tizen • To access local device and platform resources

• Describes the web application itself • Follows W3C widget Spec, and Tizen-

specific features • <name> : application name • <widget version=“x.y.z”> attribute • <content src=“start_file_name.html”/> • <icon src=“icon_file_name.png” /> • <author> • <feature>: Each feature has a corresponding

URL from which you can obtain more information about the feature

config.xml• <tizen:privilege> element. List any privileges

application requires • <tizen:application id=“…”> attribute. Unique

application identifier • <tizen:application required_version=“”>

attribute. The minimum required platform on which the application can run

• <tizen:app-control> To make use of certain functionality provided by another application

• <tizen:app-widget> Show some dynamically updated content from another application directly on the home screen

• 基于开源的javascript库 – Such as jQuery mobile, jquery, globalize

• 提供许多具有相同外貌与观感的组件

Tizen Web UI framework


136

!9

• 概述 – JavaScript开发移动web应⽤用程序的框架 –包括优化等功能UI控件,事件处理程序,动画效果,Ajax通信 –包括HTML、CSS、JavaScript –基于html5的⽤用户界⾯面系统旨在使响应web站点和应⽤用程序 –移动⽤用户界⾯面;使⽤用基于标记的HTML标记(数据- *属性、css类)

• ⽀支持平台 –Apple iOS, Android, Windows Phone, Blackberry, Palm WebOS, Firefox Mobile, Chrome for

Android, Skyfire, Opera Mobile, Meego, Tizen, Samsung Bada, Kindle, … • 下载

– From jquerymobile.com or using jQuery Mobile CDN (Contents Delivery Network) • Comparison with Sencha Touch

–Superior in terms of portability, performance, entry barrier, and library size

jQuery Mobile

• 设计和开发为多种⽂文化服务的应⽤用程序 • jQuery.glob.all.js 包括⼤大概350种⽂文化 (date, number, currency)

Globalization

2. Native Application Model


136

!13

• 界⾯面应⽤用程序 –有⼀一个图形⽤用户界⾯面 –只有⼀一个可以在前台

• 服务应⽤用程序 –它没有图形⽤用户界⾯面(背景) –显⽰示任务切换器(它提供了所有正在运⾏行的应⽤用程序)的列表,但是没有事件发⽣生时如果⽤用户选择

–有⽤用的执⾏行需要定期运⾏行或持续的活动,但不需要任何⽤用户干预

Native 应⽤用程序


136

!14

• Tizen多任务 –只有⼀一个Tizen⽀支持UI应⽤用程序可以运⾏行在前台,其余应⽤用程序在后台运⾏行 –确定哪些UI应⽤用程序是运⾏行在前台

• 使⽤用任务切换器 • 使⽤用主菜单图标

–当结束键或终⽌止系统内存低 • 内存溢出政策

–低内存运⾏行系统时,系统开始终⽌止应⽤用程序⼀一个接⼀一个,直到⾜足够的内存再次可⽤用 –⽤用户最后放置他们的背景

• 多任务优先级

• 系统事件处理 –电池的事件

• 检查设备的电池电量使⽤用OnBatteryLevelChanged()或OnBatteryLevelChangedInPercentage()事件处理程序 • 例)空;终⽌止应⽤用程序,关键;停⽌止使⽤用多媒体功能

–内存事件 • 使⽤用OnLowMemory()事件处理程序来释放堆中未使⽤用的内存

– 屏幕事件(只适⽤用于UI应⽤用程序) • 当OnScreenOff(),减少电⼒力消耗通过释放激活资源(如3 d、媒体和传感器)不再是⽤用来进⼊入睡眠模式

– 检查点的事件 • 为了避免由于意外终⽌止导致的数据丢失，使⽤用OnAppChechpointing()事件处理程序保存应⽤用程序状态或上下⽂文的应⽤用程序注册表或设备存储

Native 应⽤用程序模型

!16

• ⼀一个框架是由UI应⽤用程序,由AddFrame()初始化 • 应⽤用程序初始化后,它可以处理事件和其状态设置为运⾏行 • 应⽤用程序使⽤用OnAppTerminating()事件处理程序释放资源

Life Cycle of Native Applications


136

!17

• 启动 – UI应⽤用程序;从主菜单中,任务切换器,运⾏行应⽤用程序或者当注册条件满⾜足 –服务应⽤用;从另⼀一个应⽤用程序

• 开始的时候, –进程管理器加载必要的库和可执⾏行⼆二进制到内存中 –创建实例的应⽤用程序,执⾏行OspMain()

• 初始化,之前应⽤用程序加载,OnAppInitializing()

启动应⽤用程序


136

!18

• When, – Tizen native 应⽤用程序 itself calls the Terminate() – The system forced the 应⽤用程序 to shut down

• Memory or battery power is extremely low – Handled in the OnAppTerminating()

• Free its resources and terminates • Allocated UI controls, such as the form and its child controls are also released • save the 应⽤用程序's states into 应⽤用程序 registry

• urgent termination – triggered by the power-off and OOM – this method is not likely to be called, so the 应⽤用程序 should save the critical data

as often as possible. (check point or callback for low memory)

• normal termination – triggered by self or other 应⽤用程序s – this method is executed properly (more time but limit of 3-5 seconds)

终⽌止应⽤用程序


29

!19应⽤用程序状态转换

Paused •Application is not visible for the user

Running•While the UI app is running, it can switch between the background and foreground•During the switch, the window state of the app changes •The service app always runs in the background

Initializing•App framework initializes the application•The app data saved on the previous run is restored•For UI app, the app's frame must be created and added explicitly in app_create_cb()

Terminated•App framework removes the app from memory


136

!20

• full-screen Tizen::Ui::Controls::Frame container that creates the top-level window –必须有⾄至少⼀一个帧/应⽤用程序

Tizen ⽤用户接⼝口

!21

• One frame in a UI application which is the top-level main window • The frame has three states

帧状态转换

State: MinimizedStatus: Invisible, Graphic / media processing and sensor manipulations are discontinuedTriggered by:1. HOME key is pressed2. Another UI application has been launched

State: Deactivated Status: No input to deactivated frame, partially shownTriggered by:1. Another frame is located on top of the current frame2. Another window, such as an incoming call, pop-up, or alarm is displayed

State: Activated Status: Fully visible, receive inputTriggered by:1. User selects the application on task switcher2. User presses the main menu icon3. A window that had caused the application to become deactivated is terminated

• 注册有特定的启动条件的应⽤用程序 –启动条件得到满⾜足时,注册的应⽤用程序⾃自动启动

• 注册 – At runtime, AppManager::RegisterAppLaunch() method with privilege

• http://tizen.org/privilege/application.launch –在应⽤用程序安装时,在清单⽂文件中指定的条件
