Introduction Android Architecture Application Development Demo
What is Android?
● What is Android??● Android Features.
– Application framework
– Dalvik virtual machine
– Integrated browser
– Optimized graphics
– SQLite
– Media support
– GSM Telephony (hardware dependent)
– Bluetooth, EDGE, 3G, and WiFi (hardware dependent)
– Camera, GPS, compass, and accelerometer (hardware dependent)
– Rich development environment

Android Architecture
Android Architecture
● Linux Kernel ● 2.6 -> core system
– Security,– memory management, – process management, – network stack, and – driver model.
Android Architecture
● Library– System C library (libc)– Media Libraries - based
on PacketVideo's OpenCORE;
– Surface Manager– LibWebCore– SGL– 3D libraries– FreeType - bitmap and
vector font rendering– SQLite
Android Architecture
● Android runtime– Dalvik VM– Not a Java VM
● register based
– one instance per application
– memory optimized– uses Linux to manage
memory and multi-threading
Android Architecture
● Application Framework● Service and System
– Views
– Content providers
– Resource manager
– Notification manager
– Activity manager
● All Java classes● Simplify the reuse of
components● Any application can publish
its capabilities and any other application may then make use of those capabilities
Android Architecture
● Applications● Core Applications
– email client, – SMS program, – calendar, – maps, – browser, – contacts, and others
● All applications are written using the Java programming language.
Agenda
Intro Android Architecture Application Development Demo
Development Environment
● Eclipse Based● Android SDK,
– http://developer.android.com/sdk/index.html● Android Development Tools (ADT) plugin for Eclipse
– http://developer.android.com/sdk/eclipse-adt.html● Emulator (AVD)
or● Target Devices
– USB Connection
Development Environment
● Netbean Based● Android SDK,
– http://developer.android.com/sdk/index.html● Android plugin for Netbeans
– http://kenai.com/projects/nbandroid/downloads/download/updatecenter/updates.xml
● Emulator (AVD)or
● Target Devices– USB Connection
Development Environment
● Command Line Based● Android SDK,
– http://developer.android.com/sdk/index.html● Ant + Bash + editor,● Emulator (AVD),
or● Target Devices
– USB Connection
Reference: http://developer.android.com/guide/developing/projects/projects-cmdline.html
Development Environment
● Web Based (App Inventor)● Android SDK,
– http://developer.android.com/sdk/index.html● Web Browser,
– http://www.appinventorbeta.com● Emulator (AVD),
or● Target Devices
– USB Connection
Programming Model
No single entry point – main()Run when needed.
Programming Model
● Activity– Executable unit– Has UI– 1 application can have
multiple Activity● Services
– Similar to Activity– No UI– Run in Background
● Content Providers– Makes application's data
available to other– Can be:
● File system,● Database (SQLite)● Other
– Targeted by: ContentResolver
● Broadcast Receiver– Respond to broadcast
messages.
● Application Components
Where is the Tools?
● android
● Dalvik Debug Monitor Server (ddms)
● dmtracedump
● Draw 9-patch
● Android Emulator (emulator)
● Hierarchy Viewer (hierarchyviewer)
● hprof-conv
● layoutopt
● mksdcard
● Monkey
● monkeyrunner
● ProGuard
● sqlite3
● traceview
● zipalign

Intro Android Architecture Application Development Demo
Lets try to Develop.
How do I create some Project?
Which one? Eclipse Based,
or
Command Line
Android + Eclipse
Android + Bash (Ant)
Requirement:● Ant● Shell / Bash
atau
Create a Project.
Run in terminal:
$ android create project \
target <target> \
name <project name> \
path <path to project> \
activity <activity name> \
package <package name>
Example:
$ android create project \
target 7 \
name CobaAndroid \
path ./CobaAndroid \
activity CobaActivity \
package com.android.main
Project Structure
└── CobaAndroidProject

│ │ └── main.xml
│ └── values
│ └── strings.xml
└── src
└── com
└── android
└── main
└── CobaAndroidActivity.java
Running it...
Just type:
$ emulator avd <avd_name> &
[wait a moment]
$ ant install
$ adb shell 'am start n <package.name>/.<ActivityName>'
Debugging it...
Run from terminal:
$ ddms
Deployment
● Debug● Target: Development
● Release● Target: Market● Unsigned● Signed (for Market)
