App Presentation

Are you hungry?
Presentations
– Talk about a cool app
•
•
•
•
Download the app or apps (yes, you might need to pay a few bucks)
PPT Slides with app views
Compare to existing apps
Use/search for app reviews
– Talk about something interesting in mobile computing
•
•
E.g., android on Intel, qualcomm android tools, new/old company
A few slides and be prepared to answer (tough) questions
– 15 minutes max, but in depth (we are all experts)
– Be prepared. If you are not prepared (i.e., haven’t spent enough time figuring everything out),
ask to present next time. Don’t waste our time.

platform
• I will use windows
• Linux is fine
• You can use MAC, but will need to be a fairly
experienced MAC user. Otherwise, try using a
windows virtual machine or, if your machine
can boot into windows, use that.
• You must download and view powerpoint
documents in class
Adobe Connect
• Go to
– http://udel.adobeconnect.com/bohacek
• Log in as guest
Get Eclipse
• Complete information is also here:
http://developer.android.com/sdk/installing.html
• Download Eclipse Indigo Classic (v3.7.1)
– http://www.eclipse.org/downloads/packages/eclipse-classic371/indigosr1
– Note, if you have eclipse, please upgrade to Eclipse Classic
v3.7.1, that way, we all have the same version.
• After downloaded, decompress in a directory name eclipse
• Note, there is no installation for eclipse. Once it is
decompressed, you are ready to run it. But you can only
start eclipse by opening a file browser and double clicking
on eclipse.exe
Get JDK
• Go to
http://www.oracle.com/technetwork/java/jav
ase/downloads/index.html
• Get JDK6 or JDK5 (not JDK7 and not JRE)
– http://www.oracle.com/technetwork/java/javase/
downloads/index.html
– Scroll down a bit to JDK 6
– Perhaps you already have JDK5 or 6
• Check c:\program files\java\jdk1.X.yyy, where X=5 or 6
Get Android SDK
• Go to http://developer.android.com/sdk/index.html
• Install
– Will check that the correct version of jdk is installed.
– install in c:\Android
• After installing SDK, the SDK manager should run
– Select SDK Platform-tools
– Download each API version (or at least the ones >2.0)
• However, don’t download every package within the API version (it
takes to long). Instead, select SDK platform, samples, google api
and then the package for you phone.
– Also, download Android Support package
– And, google USB Driver package

directory. (maybe it is already correctly filled in)
