Introduction to Project: phase I

Process Form a group

Pick a topic

Requirement Engineering

Design

Implementation

Testing and documentation

Form a group

Organization 4-5 people

Inform me by Thursday (Sept. 19th)

Inform me if you do not have a group

Work assignments You decide the way to manage the group and assign

work

There can be some people working only on some phase of the project, e.g., requirement, testing

Pick a topic

Predefined topic Will introduce the topics later

Tell me by next Tuesday which one you choose

Other topics You can choose other topics, but it should be still be an

android project

Tell me by Thursday, if you want to work on other topics

We can schedule a time to talk about the details

Environment Setup

Android Development I

History of android An open source mobile operating system

Oct 2003: Palo Alto

Andy Rubin, and 3 other colleagues

A digital camera system at beginning

Aug 2005: acquired by Google

Oct. 2008: HTC dream, the first android phone

Most popular mobile system (market share 50%+)

1 million plus apps


Introduction to Android Based on Linux system The programming language is Java Jar files are transformed to app Apps are installed to the system, and then execute

d on the Dalvik virtual machine Dalvik VM: a variant of JVM Why? Smaller code size.


Android stock apps

Also called built-in apps Apps included in the android system / sdk Like IE in windows Including: phone, sms messenger, contact manage

r, web browser, clock, etc.

Emulator

People do not want to develop software using mobile device directly, why? Too slow

Hardware incompatibilities

Handling of multiple devices

Emulator A virtual android mobile phone running on the

host machine

Emulator looks like…

Emulator

Simulates almost everything about a mobile phone Run apps

Time

Make/receive phone calls, send/receive messages

Phone rotation

Battery level, AC on / off

GPS locations

Audio recording

Emulator

Something it currently cannot do Take pictures / record video (Just have it with

web camera)

Most Sensors

Other Positions (except for portrait and landscape)

Light

Phone specific devices, such as infrared emitter

Interactions between emulator and your host system

The emulator can access internet Adb tool set to transfer data between the emu

lator and the host system Telnet to 5554 to control the emulator (provid

ing a shell of the emulator) Emulators can interact with each other

Android Development

Download Android ADT Bundle http://developer.android.com/sdk/index.html Extract the zip file

Start eclipse

Android Development

Download Android SDK http://

developer.android.com/sdk/index.html#ExistingIDE

Extract the zip file Open SDK Manager.exe for update (usually no upd

ates) Start eclipse

Android Development

Install Eclipse ADT Go to eclipse, Help - > Install New Software

Input https://dl-ssl.google.com/android/eclipse/

Install all components

Create An Android project

Go to new project

Select Android

Input a name for you project

Click next for all steps

Create a new virtual device

Go to virtual device manager Add a device Give a name to the virtual device Select memory, SD card, etc.

Compile and Run

Create the hello world android project Run as an android project Wait for the system to start and go to the

app hello world And that’s it!
