附录1 英文原文
Application Fundamentals
httpdeveloperandroidcomguidetopicsfundamentalshtml
Android applications are written in the Java programming language The compiled Java code — along with any data and resource files required by the application — is bundled by the aapt tool into an Android package an archive file marked by an apk suffix This file is the vehicle for distributing the application and installing it on mobile devices it＇s the file users download to their devices All the code in a single apk file is considered to be one application
In many ways each Android application lives in its own world
1 By default every application runs in its own Linux process Android starts the process when any of the application＇s code needs to be executed and shuts down the process when it＇s no longer needed and system resources are required by other applications
2 Each process has its own virtual machine (VM) so application code runs in isolation from the code of all other applications
3 By default each application is assigned a unique Linux user ID Permissions are set so that the application＇s files are visible only to that user and only to the application itself — although there are ways to export them to other applications as well
It＇s possible to arrange for two applications to share the same user ID in which case they will be able to see each other＇s files To conserve system resources applications with the same ID can also arrange to run in the same Linux process sharing the same VM
Application Components
A central feature of Android is that one application can make use of elements of other applications (provided those applications permit it) For example if your application needs to display a scrolling list of images and another application has developed a suitable scroller and made it available to others you can call upon that scroller to do the work rather than develop your own Your application doesn＇t incorporate the code of the other application or link to it Rather it simply starts up that piece of the other application when the need arises
For this to work the system must be able to start an application process when any part of it is needed and instantiate the Java objects for that part Therefore unlike applications on most other systems Android applications don＇t have a single entry point for everything in the application (no main() function for example) Rather they have essential components that the system can instantiate and run as needed There are four types of components
Activities
An activity presents a visual user interface for one focused endeavor the user can undertake For example an activity might present a list of menu items users can choose from or it might display photographs along with their captions A text messaging application might have one activity that shows a list of contacts to send messages to a second activity to write the message to the chosen contact and other activities to review old messages or change settings Though they work together to form a cohesive user interface each activity is independent of the others Each one is implemented as a subclass of the Activity base class
An application might consist of just one activity or like the text messaging application just mentioned it may contain several What the activities are and how many there are depends of course on the application and its design Typically one of the activities is marked as the first one that should be presented to the user when the application is launched Moving from one activity to another is accomplished by having the current activity start the next one
Each activity is given a default window to draw in Typically the window fills the screen but it might be smaller than the screen and float on top of other windows An activity can also make use of additional windows — for example a popup dialog that calls for a user response in the midst of the activity or a window that presents users with vital information when they select a particular item onscreen
The visual content of the window is provided by a hierarchy of views — objects derived from the base View class Each view controls a particular rectangular space within the window Parent views contain and organize the layout of their children Leaf views (those at the bottom of the hierarchy) draw in the rectangles they control and respond to user actions directed at that space Thus views are where the activity＇s interaction with the user takes place
For example a view might display a small image and initiate an action when the user taps that image Android has a number of readymade views that you can use — including buttons text fields scroll bars menu items check boxes and more
A view hierarchy is placed within an activity＇s window by the ActivitysetContentView() method The content view is the View object at the root of the hierarchy (See the separate User Interface document for more information on views and the hierarchy)
Services
A service doesn＇t have a visual user interface but rather runs in the background for an indefinite period of time For example a service might play background music as the user attends to other matters or it might fetch data over the network or calculate something and provide the result to activities that need it Each service extends the Service base class
A prime example is a media player playing songs from a play list The player application would probably have one or more activities that allow the user to choose songs and start playing them However the music playback itself would not be handled by an activity because users will expect the music to keep playing even after they leave the player and begin something different To keep the music going the media player activity could start a service to run in the background The system would then keep the music playback service running even after the activity that started it leaves the screen
It＇s possible to connect to (bind to) an ongoing service (and start the service if it＇s not already running) While connected you can communicate with the service through an interface that the service exposes For the music service this interface might allow users to pause rewind stop and restart the playback
Like activities and the other components services run in the main thread of the application process So that they won＇t block other components or the user interface they often spawn another thread for timeconsuming tasks (like music playback) See Processes and Threads later
Broadcast receivers
A broadcast receiver is a component that does nothing but receive and react to broadcast announcements Many broadcasts originate in system code — for example announcements that the timezone has changed that the battery is low that a picture has been taken or that the user changed a language preference Applications can also initiate broadcasts — for example to let other applications know that some data has been downloaded to the device and is available for them to use
An application can have any number of broadcast receivers to respond to any announcements it considers important All receivers extend the BroadcastReceiver base class
Broadcast receivers do not display a user interface However they may start an activity in response to the information they receive or they may use the NotificationManager to alert the user Notifications can get the user＇s attention in various ways — flashing the backlight vibrating the device playing a sound and so on They typically place a persistent icon in the status bar which users can open to get the message
Content providers
A content provider makes a specific set of the application＇s data available to other applications The data can be stored in the file system in an SQLite database or in any other manner that makes sense The content provider extends the ContentProvider base class to implement a standard set of methods that enable other applications to retrieve and store data of the type it controls However applications do not call these methods directly Rather they use a ContentResolver object and call its methods instead A ContentResolver can talk to any content provider it cooperates with the provider to manage any interprocess communication that＇s involved
See the separate Content Providers document for more information on using content providers
Whenever there＇s a request that should be handled by a particular component Android makes sure that the application process of the component is running starting it if necessary and that an appropriate instance of the component is available creating the instance if necessary
Activating components intents
Content providers are activated when they＇re targeted by a request from a ContentResolver The other three components — activities services and broadcast receivers — are activated by asynchronous messages called intents An intent is an Intent object that holds the content of the message For activities and services it names the action being requested and specifies the URI of the data to act on among other things For example it might convey a request for an activity to present an image to the user or let the user edit some text For broadcast receivers the
Intent object names the action being announced For example it might announce to interested parties that the camera button has been pressed
There are separate methods for activating each type of component
1 An activity is launched (or given something new to do) by passing an Intent object to
ContextstartActivity() or ActivitystartActivityForResult() The responding activity can look at the initial intent that caused it to be launched by calling its getIntent() method Android calls the activity＇s onNewIntent() method to pass it any subsequent intents One activity often starts the next one If it expects a result back from the activity it＇s starting it calls startActivityForResult() instead of startActivity() For example if it starts an activity that lets the user pick a photo it might expect to be returned the chosen photo The result is returned in an Intent object that＇s passed to the calling activity＇s onActivityResult() method
2 A service is started (or new instructions are given to an ongoing service) by passing an Intent object to ContextstartService() Android calls the service＇s onStart() method and passes it the Intent object Similarly an intent can be passed to ContextbindService() to establish an ongoing connection between the calling component and a target service The service receives the Intent object in an onBind() call (If the service is not already running bindService() can optionally start it) For example an activity might establish a connection with the music playback service mentioned earlier so that it can provide the user with the means (a user interface) for controlling the playback The activity would call bindService() to set up that connection and then call methods defined by the service to affect the playback
A later section Remote procedure calls has more details about binding to a service

应程序基础Android Developers
Android应程序Java编程语言开发aapt工具编译Java代码连应程序需数资源文件起包Android包文件中文件apk作扩展名文件分发安装应程序移动设备载体户载设备文件单apk文件中代码认应程序
角度Android应程序存世界中：
1 默认情况应程序均运行Linux进程中应程序中代码需执行时Android启动进程需进程应程序请求系统资源时关闭进程
· 2 进程独虚拟机（VM）应程序代码应程序代码隔离运行
3 默认情况应程序均赋予唯Linux户ID加权限设置应程序文件仅户应程序见——方法文件样应程序访问
1 应程序组件
Android核心特性应程序应程序元素（果应程序允许话）例果应程序需显示图片卷动列表应程序已开发合允许应程序话直接调卷动列表完成工作开发应程序没吸纳链接应程序代码需求时候启动应程序功部分
