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)
