The document presents an overview of beginning Android development, covering its architecture, application development processes, and various development environments such as Eclipse and command line. It details key features of Android, including its core applications, programming model, and related tools for debugging and deploying applications. Additionally, it provides guidance on creating a new project and resources for further learning about Android development.

3. 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

5. Android Architecture

6. Android Architecture
● Linux Kernel
● 2.6 -> core system
– Security,
– memory management,
– process management,
– network stack, and
– driver model.

7. 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

8. 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

9. 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

10. Android Architecture
● Applications
● Core Applications
– email client,
– SMS program,
– calendar,
– maps,
– browser,
– contacts, and others
● All applications are
written using the Java
programming
language.

12. 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

13. 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

14. 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

15. 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

16. Programming Model
No single entry point – main()
Run when needed.

17. Programming Model
● Application Components
● Activity ● Content Providers
– Executable unit – Makes application's data
available to other
– Has UI
– Can be:
– 1 application can have ● File system,
multiple Activity ● Database (SQLite)
● Services ● Other
– Targeted by:
– Similar to Activity
ContentResolver
– No UI ● Broadcast Receiver
– Run in Background
– Respond to broadcast
messages.

18. 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

20. Lets try to Develop.

21. How do I create some Project?
Which one?
 Eclipse Based,
or
 Command Line

22. Android + Eclipse

23. Android + Bash (Ant)
Requirement:
● Ant
● Shell / Bash
atau

24. Create a Project.
Run in terminal: Example:
$ android create project $ android create project
­­target <target> ­­target 7
­­name <project name> ­­name CobaAndroid
­­path <path to project> ­­path ./CobaAndroid
­­activity <activity name> ­­activity CobaActivity
­­package <package name> ­­package com.android.main

25. Project Structure
└── CobaAndroidProject
├── AndroidManifest.xml
├── bin
├── build.properties
├── build.xml
├── default.properties
├── libs
├── local.properties
├── proguard.cfg
├── res
│ ├── drawable­hdpi
│ │ └── icon.png
│ ├── ...
│ ├── layout
│ │ └── main.xml
│ └── values
│ └── strings.xml
└── src
└── com
└── android
└── main
└── CobaAndroidActivity.java

26. Running it...
Just type:
$ emulator ­avd <avd_name> &
[wait a moment]
$ ant install
$ adb shell 'am start ­n
<package.name>/.<ActivityName>'

27. Debugging it...
Run from
terminal:
$ ddms

28. Deployment
● Debug
● Target: Development
● Release
● Target: Market
● Unsigned
● Signed (for Market)
