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. • Web site that talk about apps and mobile technology (you should know keep up to date with these) • techcrunch.com • http://www.crunchbase.com/ • TechstarsApp showcase: http://techstars.appstores.com/ • Kichstarter.com • http://www.kickstarter.com/discover/categories/technology?ref=sidebar • http://www.businessinsider.com/sai • Search on android app and find many articles on different apps • http://allthingsd.com/

  3. 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

  4. Adobe Connect • Go to • http://udel.adobeconnect.com/bohacek • Log in as guest

  5. 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-classic-371/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

  6. Get JDK • Go to http://www.oracle.com/technetwork/java/javase/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

Instead, select SDK platform, samples, googleapi and then the package for you phone. • Also, download Android Support package • And, google USB Driver package

  8. Install ADT Eclipse plugin • For instructions, also see http://developer.android.com/sdk/eclipse-adt.html#installing • Start eclipse • Help –> install new software • Click Add, in the top-right corner. • In the Add Repository dialog that appears, enter "ADT Plugin" for the Name and the following URL for the Location: https://dl-ssl.google.com/android/eclipse/ • Click OK • Note: If you have trouble acquiring the plugin, try using "http" in the Location URL, instead of "https" (https is preferred for security reasons). • In the Available Software dialog, select the checkbox next to Developer Tools and click Next. • In the next window, you'll see a list of the tools to be downloaded. Click Next. • Read and accept the license agreements, then click Finish. • When the installation completes, restart Eclipse. • Configuring the ADT Plugin • Select Window > Preferences... to open the Preferences panel (Mac OS X: Eclipse > Preferences). • Select Android from the left panel. • You may see a dialog asking whether you want to send usage statistics to Google. If so, make your choice and click Proceed. You cannot continue with this procedure until you clickProceed. • For the SDK Location in the main panel, click Browse... and locate your downloaded SDK directory. (maybe it is already correctly filled in) • Click Apply, then OK.
