Android Development I

Android system & Emulator

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
Android Development I

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
executed on the Dalvik virtual machine

Dalvik VM: a variant of JVM

Why? Smaller code size.
Android Development I
Android stock apps

Also called built-in apps

Apps included in the android system / sdk

Like IE in windows

Including: phone, sms messenger, contact manager,
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
emulator and the host system
Telnet to 5554 to control the emulator
(providing a shell of the emulator)
Emulators can interact with each other
Android Development

Download Android Studio

https://developer.android.com/sdk/index.html

Extract the zip file

Start
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!
