telephonyconnectionservice 示例 -回复

telephonyconnectionservice 示例-回复什么是TelephonyConnectionService？TelephonyConnectionService是一种服务，它可以让用户在进行多种通话（例如语音通话、视频通话等）时进行多任务操作，这意味着该服务可以在不中断通话的情况下执行其他任务。

这个服务主要是针对移动设备上的电话应用开发的，是Android的一个重要功能。

TelephonyConnectionService主要有哪些功能？TelephonyConnectionService主要有以下功能：1. 建立和维护通话：TelephonyConnectionService可以允许用户与其他人建立通话，包括语音通话、视频通话等，并可以在通话中继续执行其他任务。

2. 通话控制：TelephonyConnectionService可以让用户在通话中控制通话的状态，例如挂断、静音、免提等。

3. 通话记录：在通话结束后，TelephonyConnectionService会记录通话的信息，例如通话时间、通话方、通话类型等信息，以便用户进行查看、管理、分析等操作。

4. 通话扩展：TelephonyConnectionService可以允许第三方开发者进行扩展，例如增加新的通话功能、自定义通话处理等。

5. 统一接口：TelephonyConnectionService提供了一个统一的接口，使得各种通话方式可以通过相同的方式进行处理。

如何使用TelephonyConnectionService？使用TelephonyConnectionService需要一定的开发经验，可以参照以下步骤进行：1. 继承ConnectionService类，并实现其中的方法，例如onCreateOutgoingConnection()、onCreateIncomingConnection()等。

这些方法可以用于建立、管理通话等功能。

Android应用架构外文翻译

Android Application Architectureauthor：Lars V ogel1、AndroidManifest.xmlThe components and settings of an Android application are described in the file AndroidManifest.xml. For example all Activities and Services of the application must be declared in this file.It must also contain the required permissions for the application. For example if the application requires network access it must be specified here.<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="/apk/res/android"package="de.vogella.android.temperature"android:versionCode="1"android:versionName="1.0"><application android:icon="@drawable/icon"android:label="@string/app_name"><activity android:name=".Convert"android:label="@string/app_name"><intent-filter><action android:name="android.intent.action.MAIN" /><category android:name="UNCHER" /></intent-filter></activity></application><uses-sdk android:minSdkVersion="9" /></manifest>The package attribute defines the base package for the Java objects referred to in this file. If a Java object lies within a different package, it must be declared with thefull qualified package name.Google Play requires that every Android application uses its own unique package. Therefore it is a good habit to use your reverse domain name as package name. This will avoid collisions with other Android applications.android:versionName and android:versionCode specify the version of your application. versionName is what the user sees and can be any String.versionCode must be an integer. The Android Market determine based on the versionCode, if it should perform an update of the applications for the existing installations. You typically start with "1" and increase this value by one, if you roll-out a new version of your application.The tag <activity> defines an Activity, in this example pointing to the Convert class in the de.vogella.android.temperature package. An intent filter is registered for this class which defines that this Activity is started once the application starts (action android:name="android.intent.action.MAIN"). The category definition category android:name="UNCHER" defines that this application is added to the application directory on the Android device.The @string/app_name value refers to resource files which contain the actual value of the application name. The usage of resource file makes it easy to provide different resources, e.g. strings, colors, icons, for different devices and makes it easy to translate applications.The "uses-sdk" part of the "AndroidManifest.xml" file defines the minimal SDK version for which your application is valid. This will prevent your application being installed on devices with older SDK versions.2、R.java and ResourcesThe " gen " directory in an Android project contains generated values. R.java is a generated class which contains references to certain resources of the project.These resources must be defined in the "res" directory and can be XML files, icons or pictures. You can for example define values, menus, layouts or animations via XML files.If you create a new resource, the corresponding reference is automatically created in R.java via the Eclipse ADT tools. These references are static int values and defineID's for the resources.The Android system provides methods to access the corresponding resource via these ID's.For example to access a String with the R.string.yourString ID, you would use the getString(R.string.yourString)) method.R.java is automatically created by the Eclipse development environment, manual changes are not necessary and will be overridden by the tooling.3、AssetsWhile the res directory contains structured values which are known to the Android platform, the assets directory can be used to store any kind of data. You access this data via the AssetsManager which you can access the getAssets() method.AssetsManager allows to read an assets as InputStream with the open() method.// Get the AssetManagerAssetManager manager = getAssets();// Read a Bitmap from Assetstry {InputStream open = manager.open("logo.png");Bitmap bitmap = BitmapFactory.decodeStream(open);// Assign the bitmap to an ImageView in this layoutImageView view = (ImageView) findViewById(R.id.imageView1);view.setImageBitmap(bitmap);} catch (IOException e) {e.printStackTrace();}4、Activities and LayoutsThe user interface for Activities is defined via layouts. The layout defines the included Views (widgets) and their properties.A layout can be defined via Java code or via XML. In most cases the layout is defined as an XML file.XML based layouts are defined via a resource file in the /res/layout folder. This file specifies the ViewGroups, Views, their relationship and their attributes forthis specific layout.If a View needs to be accessed via Java code, you have to give the View a unique ID via the android:id attribute. To assign a new ID to a View use @+id/yourvalue. The following shows an example in which a Button gets the "button1" ID assigned.<Buttonandroid:id="@+id/button1"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="Show Preferences" ></Button>By conversion this will create and assign a new yourvalue ID to the corresponding View. In your Java code you can later access a View via the method findViewById(R.id.yourvalue).Defining layouts via XML is usually the preferred way as this separates the programming logic from the layout definition. It also allows the definition of different layouts for different devices. You can also mix both approaches.5、Reference to resources in XML filesIn your XML files, for example your layout files, you can refer to other resources via the @ sign.For example, if you want to refer to a color which is defined in a XML resource, you can refer to it via @color/your_id. Or if you defined a "hello" string in an XML resource, you could access it via @string/hello.6、Activities and LifecycleThe Android system controls the lifecycle of your application. At any time the Android system may stop or destroy your application, e.g. because of an incoming call. The Android system defines a lifecycle for Activities via predefined methods. The most important methods are:onSaveInstanceState() - called if the Activity is stopped. Used to save data so that the Activity can restore its states if re-startedonPause() - always called if the Activity ends, can be used to release resource orsave dataonResume() - called if the Activity is re-started, can be used to initialize fields7、Configuration ChangeAn Activity will also be restarted, if a so called "configuration change" happens.A configuration change happens if an event is triggered which may be relevant for the application. For example if the user changes the orientation of the device (vertically or horizontally). Android assumes that an Activity might want to use different resources for these orientations and restarts the Activity.In the emulator you can simulate the change of the orientation via CNTR+F11.You can avoid a restart of your application for certain configuration changes via the configChanges attribute on your Activity definition in your AndroidManifest.xml. The following Activity will not be restarted in case of orientation changes or position of the physical keyboard (hidden / visible).<activity android:name=".ProgressTestActivity"android:label="@string/app_name"android:configChanges="orientation|keyboardHidden|keyboard"> </activity>8、ContextThe class android.content.Context provides the connections to the Android system. It is the interface to global information about the application environment. Context also provides access to Android Services, e.g. the Location Service. Activities and Services extend the Context class and can therefore be used as Context.Android应用架构作者：Lars Vogel(拉尔斯·沃格尔)1、AndroidManifest.xml一个Android应用程序的组件和设置描述文件中的AndroidManifest.xml。

Android平台架构及特性

Android平台架构及特性Android平台架构及特性 Android系统的底层是建⽴在Linux系统之上，改平台由操作系统、中间件、⽤户界⾯和应⽤软件四层组成，它采⽤⼀种被称为软件叠层（Software Stack）的⽅式进⾏构建。

好处：这种软件叠层结构使得层与层互相分离，明确各层的分⼯，这种分⼯保证了层与层之间的低耦合，当下层内或者层下发⽣改变时，上层应⽤程序⽆需任何改变。

下图显⽰Android系统的体系结构：1.应⽤程序层（Application） Android平台不仅仅是操作系统，也包含了许多应⽤程序，诸如SMS短信客户端程序、电话拨号程序、图⽚浏览器、Web浏览器等应⽤程序。

这些应⽤程序都是⽤Java语⾔编写的，并且这些应⽤程序都是可以被开发⼈员开发的其他应⽤程序所替换，这点不同于其他⼿机操作系统固化在系统内部的系统软件，更加灵活和个性化。

我们编写的主要是这⼀层上的应⽤程序。

2.应⽤程序架构层（Application Framework）应⽤程序框架层是我们从事Android开发的基础，很多核⼼应⽤程序也是通过这⼀层来实现其核⼼功能的，该层简化了组件的重⽤，开发⼈员可以直接使⽤其提供的组件来进⾏快速的应⽤程序开发，也可以通过继承⽽实现个性化的拓展。

Android应⽤程序框架提供了⼤量的API供开发者使⽤。

a） Activity Manager（活动管理器）管理各个应⽤程序⽣命周期以及通常的导航回退功能b） Window Manager（窗⼝管理器）管理所有的窗⼝程序c） Content Provider（内容提供器）使得不同应⽤程序之间存取或者分享数据d） View System（视图系统）构建应⽤程序的基本组件e） Notification Manager(通告管理器)使得应⽤程序可以在状态栏中显⽰⾃定义的提⽰信息f） Package Manager（包管理器）Android系统内的程序管理g）Telephony Manager(电话管理器)管理所有的移动设备功能h）Resource Manager（资源管理器）提供应⽤程序使⽤的各种⾮代码资源，如本地化字符串、图⽚、布局⽂件、颜⾊⽂件等i）Location Manager(位置管理器)提供位置服务j）XMPP Service（XMPP服务）提供Google Talk服务3.系统运⾏库层： 1)函数库（Libraries）函数是应⽤程序框架的⽀撑，是连接应⽤程序框架层与Linux内核层的重要纽带。

Android-Modem

1、概述
Android RIL（Radio Interface Layer）提供了无线硬件设备与电话服务之间的抽象层。下图 1 展示了 RIL 在 Android 体系中的位置。
图1 Android RIL 位于应用程序框架与内核之间，分成了两个部分，一个部分是 rild,它负责 socket 与应用程序框架进行通信。另外一个部分是 Vendor RIL，这个部分负责向下与 radio 进行通信。对于 RIL 的 java 框架部分，也被分成两个部分，一个是 RIL 模块，这个模块主要与下层的 rild 进行通信，另外一个是 phone 模块，这个模块直接暴露电话功能结构给应用开发用
2、L4、REX 、AMSS 之间的关系
L4 是一个微内核程序，高通的 L4 提供了操作系统最基本的操作，包括 Address Space Support( 地址空间支持 ),IPC (Inter-Process Communication, 进程间通讯 ), 和 Scheduling( 调度 ) 等。 REX 是在 L4 之上封装的服务，是一个抢占式，多任务的 RTOS ，所有的任务都以 task 的形式存在， REX 提供包括任务创建，同步，互斥，计时器，中断控制等功能的 API ，这里的 task 实际上就是我们的线程，每个 task 对应着一个线程。 REX 维护一个 task list( 双向链表 ) ，始终运行高优先级的 task 。 products 里面所有的服务包括 3g 协议栈等都是以 task 的形式跑在 rex 之上的。 AMSS― ― 高级的移动用户软件 (Advanced Mobile Subscriber Software) 技术。 AMSS 源代码实际上是 QC BREW(Binary Runtime Environment For Wireless) 平台的的底层部分，去掉了为应用程序提供接口的 AEE(application execution environment) 部分，高通平台基本上都是采用的这样的架构。

Android Phone模块基本介绍

Android Phone模块电话管理是Android 系统支持的重要的业务之一，提供接听电话，收发短信、电话薄、网络事件监听、读取用户信息等功能。

从下到上可以分为四层：硬件驱动层、RIL daemon层、Telephony框架实现层、 PHONE 应用层，下层为上层提供服务，每层之间采用不同的通讯方式交互。

RIL daemon层实现为单独的一个开机启动的进程（rild命令），通过AT命令硬件驱动层交互，Telephony JAVA框架实现层包括一个RIL抽象层，RIL抽象层中通过一个本地socket与RIL daemon层（rild）交互，Phone应用层通过Binder机制与Telephony框架交互。

一 Telephony框架Telephony框架系统类图如下图：Telephony框架层为应用层和框架层的其它服务提供Telephony服务，提供了如下几个服务：PhoneInterfaceManager服务，是ITelephony接口的实现，IccSmsInterfaceManager短消息服务，是Isms接口的实现；IccPhoneBookInterfaceManager电话本服务，是IIccPhoneBook接口的实现；PhoneSubInfo提供用户信息读取服务，是IPhoneSubInfo接口的实现；TelephonyRegistry提供应用层的消息登记服务，是ITelephonyRegistry接口的实现。

应用程序通过以下几个客户端对象使用Telephony框架提供的服务。

应用程序可以在SmsManager单例对象（通过SmsManager类的getDefault函数返回SmsManager单例对象）中访问IccSmsInterfaceManager服务,用来收发短信。

通过IccProvider一个内容提供对象提供对IccPhoneBookInterfaceManager服务的访问，读取和管理电话本。
