android Architecture

android information is come from
http://www.mindcracker.com/Story/1076/architecture-of-android

1. Applications e.g. calendar,email, SMS, maps phone,browser:
Android applications are written in the Java programming language, and they run within a virtual machine (VM). It's important to note that the VM is not a JVM as we might expect, but is the Dalvik Virtual Machine, an open source technology. Each Android application runs within an instance of the Dalvik VM, which in turn resides within a Linux-kernel managed process, as shown below.

2. Application Framework:

This is the skeleton or framework which all android developers have to follow. The developers can access all framework APIs an manage phone's basic functions like resource allocation, switching between processes or programs, telephone applications, and keeping track of the phone's physical location. Underlying all applications is a set of services and systems, including:

    Activity Manager
    Windows Manager
    Content Provider
    View System
    Package Manager
    Telephony Manager
    Resource Manager
    Location Manager
    Notification Manager

Where,

    Rich and extensible set of Views that can be used to build an application, including lists, grids, text boxes, buttons, and even an embeddable web browser.
    Content Providers that enable applications to access data from other applications (such as Contacts), or to share their own data.
    Resource Manager, providing access to non-code resources such as localized strings, graphics, and layout files.
    Notification Manager that enables all applications to display custom alerts in the status bar.
    An Activity Manager that manages the lifecycle of applications and provides a common navigation back stack.

    The architecture is well designed to simplify the reuse of components. Think of the application framework as a set of basic tools with which a developer can build much more complex tools.

    ArchAnd4.gif

3. Libraries:

This layer consists of Android libraries written in C, C++, and used by various systems. These libraries tell the device how to handle different kinds of data and are exposed to Android developers via Android Application framework. Some of these libraries includes media, graphics, 3d, SQLite, web browser library etc.

Android Libc implementation:

A custom implementation, optimized for embedded use.

    BSD license
    Small size and fast code paths
    Very fast custom pthread implementation
    Built-in support for android-specific services (system properties, log capabilities)
    Doesn't support some POSIIX features

Storage, rendering, multimedia:

Provides the main features on the Android platform:

    SQLite, a simple relational database management system (No IIPC, single file)
    WebKit, an application framework that provides foundation for building a web browser
    Media Framework, based on PacketVideo openCORE platform (codec)
    Optimized 2D//3D graphic library based on OpenGL ES

Surface Manager:

Provides a system-wide surface "composer" to render all the surfaces in a frame buffer.

    Can combined 2D and 3D surfaces
    Can use OpenGL ES and 2D hardware accelerator for its compositions

android AndroidManifest.xml (config file)

Android AndroidManifest.xml include

application
activity
service
provider
receiver
user-permission

什麼是Intent(意圖)？
強大的事件處理「Intent」(意圖)是Android很強大的一種機制。ntent（意圖）的作用與事件(event)很像，但與傳統的事件處理仍然有些差異。傳統的事件處理，講求的是「處理者（handler）的觸發」，當一事件發生時，便callback讓事件的處理者，或是直接將該事件轉送（forward）給應用程式，由應用程式決定處理方式。Android的做法是，讓每個意圖（Intent）都帶有一個動作（action），並根據不同的動作去行動。在「Intent」這樣的事件處理觀念裡，Android 試圖將事件解釋為「應用程式的意圖」或是「使用者的意圖」，並試著去解釋該意圖的目的，若 Android 系統本身能理解應用程式的意圖，便會「自行」去處理該意圖所應執行的工作。
I

The structure of intent include (Component Name, Action, Data, Categorg, Extra, Flag)

Android Component Name

i.e. target class
e.g. setComponent(), setClass(), setClassName and getComponent()

Android Action
ACTION_CALL i.e. call tel number
ACTION_EDIT
ACTION_MAIN
ACTION_SYNC
ACTION_VIEW: 使用Android內部定義的動作「ACTION_VIEW」，來「檢視」(view)一個「URL」資料，當框架看到內部定義的ACTION_VIEW動作時，便「自行」處理該Intent；處理的方式是啟動WebView並連上網“ACTION_VIEW”就可以很容易做出一個「啟動瀏覽器(WebView類別)上網」的應用程式
ACTION_DIAL
ACTION_SENDTO

現在，列舉以下三個情境，並分別實作其範例：

HelloIntentDialer: 啟動撥號器(dialer)並撥號
HelloIntentMusic: 使用者按下「Select Music」後，可以由音樂清單裡選擇音樂並撥放
HelloIntentWallpaper: 啟動Android內建的「背景圖選擇器」，讓使用者更換背景

第二個範例”HelloIntentMusic”其實是ApiDemo裡的範例，而且是很容易能了解Intent內涵的好程式。

除了action外，Intent還可以包含另外一項資訊「data」。

Intent的action指定這個Intent的「動作」是什麼，框架會依指定的動作進行處理；有些action可以附帶一筆資料，這個資料是以Uri的格式撰寫，在HelloIntentDialer的範例會再做說明。

內建的Intent有哪些呢？請參考Android Reference Guide中的Intent類別說明。上述三個範例分別使用以下三個action：

1. ACTION_CALL: 撥號
2. ACTION_GET_CONTENT: 啟動內容選取器
3. ACTION_SET_WALLPAPER: 設定Wallpaper

在進行範例講解前，可以先行閱讀Intent類別的說明。ACTION_CALL是一個內建的action，我們只要產生一個Intent物件，並定義其「action」為ACTION_CALL即可通知框架「打電話」。

Android內建的action是相當實用的應用開發機制，同時也是Android OS最具代表性的機制之一。Android內建的Intent action分為二種：

1. Activity Action: 啟動Activity的action
2. Broadcast Action: 透過廣撥器處理的action

第一種action是activity action，用途是通知框架啟動Activity，這裡提出的三個範例，都是使用activity action。Broadcast action將在Broadcast的教學裡再做說明。

Intent 應該算是 Andorid 中特有的東西。你可以在 Intent 中，指定要應用程式執行的動作 (view, edit, dial)，以及應用程式執行該動作時，所需要的資料。都指定好後，只要透過 startActivity()，Android 系統會自動尋找，最符合你指定要求的應用程式，並喚起執行該應用程式。

不過，這部份的文件還不是很完整。Reference of Available Intents 有列一些。

Android 可以利用 Intent.ACTION_VIEW 來開啟檔案且執行之,

Intent intent = new Intent( Intent.ACTION_VIEW );
File f1 = new File( "/" + vDir + "/" + vFile );

// 檔名小寫, 容易判斷副檔名
String vlowerFileName = vFile.toLowerCase();

// 影片
if( vlowerFileName.endsWith("mpg")
|| vlowerFileName.endsWith("mp4")
)
intent.setDataAndType( Uri.fromFile(f1), "video/*" );
// 音樂
else if( vlowerFileName.endsWith("mp3") )
intent.setDataAndType( Uri.fromFile(f1), "audio/*" );
// 影像
else if( vlowerFileName.endsWith("bmp")
|| vlowerFileName.endsWith("gif")
|| vlowerFileName.endsWith("jpg")
|| vlowerFileName.endsWith("png")
)
intent.setDataAndType( Uri.fromFile(

android folder

ProjectName
ProjectName/src
e.g. R.java and <activity>.java (in this example,
HelloWorldText.java,developProgram.java ), The file R.java is an auto-generated file that is added to your application by the Android plugin. This file contains pointers into the drawable, layout, and values directories (or the items within the directories, as is the case with strings and icons). You should never have to modify this file directly.

/ProjectName/assets
audio files for streaming and animation assets
jpg, html, js,css

/ProjectName/res/drawable
imageFiles, drawable-hdpi, drawable-ldpi, drawable-mdpi3

/ProjectName/res/layout
main.xml, layout, XML files

/ProjectName/res/values
string.xml, color.xml, style.xml

e.g. main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=http://schemas.android.com/apk/res/android
