The document outlines the steps to set up a development environment for Android applications, including installing the JDK, Android SDK, and Eclipse IDE. It details creating a new Android project, debugging procedures, and testing applications on various devices. Additionally, it provides information on publishing apps and best practices for development and debugging.

2. Requirements
 Android SDK
 Java JDK
 Eclipse IDE
 Some knowledge of Java programming
 A modern computer
 Guts
 And maybe a beer…

3. Setting up the JDK
 Download JDK
from Oracle
 http://www.oracl

ork/java/javase/
downloads/jdk7
-downloads-

4. Setting up the Android SDK
 http://developer.androi
d.com/sdk/index.html
 SDK Manager:
android-sdk-
windowstoolsandroid.
bat
 Update as required
4

5. Setting up Eclipse IDE
 http://www.eclipse.org/
downloads/
 Pick a “Eclipse IDE for
Java Developers”
matching your OS
 Unpack your download
5

6. Your new Android project (0)
 On boot, Eclipse will ask where to put your
projects (your workspace)
 Pick somewhere you wont forget, preferably with a
lot of space
 Install ADT plugin & restart Eclipse
 https://dl-ssl.google.com/android/eclipse/
6

7. Your new Android project (I)
 Start a new “Android Application Project”
 Give it a good name & pick an
appropriate minimum required SDK
7

8. Your new Android project (II)
 Pick a launcher icon
 Pick a starting activity
 Pick the navigation style
8

9. Your new Android project (III)
 You should get this screen when you are
done
9

10. Your new Android project (IV)
 You can also import an existing project
 Menu: ”File”>>”Import”
 Select Android project and pick the directory
path for it
10

11. Basics
 Each screen is an “activity”
 Activity = code (Java) + UI layout (XML)
 Code controls everything
 Except modifying UI layouts
 UI layout is composed of “widgets”
 A button, an image or a textbox are all
widgets
 The labels of widgets can be changed by
code
11

12. Exploring your project
 src: code
 libs: reference libraries
 bin: compiled apk
 res: all media, layouts, visuals
 res/layout: UI layout of all activities
 AndroidManifest.xml: the heart of
any Android project
 Permissions
 Declaring components
12

13. Debugging with Eclipse
 If you want to use your physical device,
remember to turn on USB debugging
 Settings >> Developer options >> USB
debugging
 Emulation
 DDMS
 LogCat
13

14. Setting up an Android emulator (I)
 Menu: “Window” >> “Android Virtual
Device Manager”
 Select “New”
 Select suitable attributes
14

15. Setting up an Android emulator (II)
 Start your virtual device first to save time
15

16. Emulating your Android
application
 Select one of your source
files
 Select the green “Run
[your program name]
button
 First run only:
 Select run as “Android
Applicaiton”
 Say “Yes” to LogCat, nyan~!
 Viola!!
16

17. Emulating your Android
application (II)
 If you didn’t start a virtual device first,
Eclipse will start one for you
 Automatically selects first compatible device
 Prompts you to create if you don’t have one
 But you have to wait for it to boot
 Might have to run again because it took too
long for the virtual device to start
17

18. Testing with other Android
devices
 Menu: “Run” >> “Run Configurations…”
 Switch to “Target” tab
 Choose “Always prompt to pick device”
 Now you get to choose a device every
time you run your application
18

19. DDMS (I)
 Menu: “Window”>>”Open
perspective”>>”DDMS”
19

20. DDMS (II)
 You can do a lot of things in the DDMS
 File dump
 Fake GPS
 Check CPU load
20

21. LogCat (I)
 Menu: “Window”>>”Show
View”>>”Other”>>”LogCat”
 A log of everything computational on the
Android device
21

22. LogCat (II)
 You can filter log data by:
 Application
 Debug level
 You can also save the log
 You can use code to send debug data to
LogCat
 Better than using “push” popup messages
22

23. Debugging with Android SDK
 Same as DDMS
 android-sdk-windowstoolsandroid.bat
23

24. Publishing your app
 Compile in “release” config
 APK file
 Mail to people you want to share
 Host on website for download
 etc.
 Publish to Google Play
 Need Google account
 USD 25 registration fee
24

25. Tricks for demoing
 Make a video capture
 Android emulator
 BlueStacks
 Droid @ Screen
25

26. BlueStacks
 http://www.bluestacks.com/
 Install a custom launcher and you are
ready to go
26

27. Droid @ Screen
 http://droid-at-
screen.ribomation.com/
 Requires Java & a USB
connection to your
Android device
 Just specify where your
/sdk/platform-
tools/adb.exe resides
27

28. Wrapping it up…
 Read the documentation
 Ask around on StackOverflow
 Plan a lot
 Don’t give up
 Practice makes perfect!
 And remember to have fun 
