Getting Started with Android Programming

1. Getting Started with Android Programming Note: if you have already installed android development tools, please check that you have the same version as described here

2. 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. • 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

7. 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, 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.

9. Subclipse • In Eclipse • Help -> install new software • Select add • In location, put  http://subclipse.tigris.org/update_1.8.x

10. Play with our set up • Enable USB debugging on you phone • Go to settings • Approach 1 (depends on phone) • Open Applications • Development • Check USB Debugging • Approach 2 • {} Developer options • Check USB debugging • Approach 3 • Look around and check USB debugging • Start eclipse • Window -> open perspective -> other -> DDMS (! Not <DDMS>) • Plug your phone via usb • Under devices (upper left) you can see your phone • If you can’t see you phone, check if you have a notification on you phone asking about whether to use USB debugging. Do not select USB storage • In the upper middle, select the File Explorer tab • Expand mnt • Expand sdcard • Expand DCM • Expand Camera • This is where your pictures are • Expand data • Should not work, since this is a protected directory that holds apps private data • On the lower/middle left, select LogCat. This shows system messages. • The messages are have level (debug, error, info,…) • You can select which messages using the menu in the middle right • Messages have tags and text • We will use these messages extensively for debugging • Near the top is a row of buttons. One button is a camera. Click on the camera and see your device screen shot

11. Play with ADB • Open a command prompt • Change dir to c:\android\android-sdk\platform-tools • > adb devices • Shows the devices you have plugged in and the serial number • >adb shell • Opens a shell on the device • > ls • >cd /data • >ls • Still fails • > su • If you have rooted you phone, this will succeed • > ls • Works! • > ps • Shows everything running

12. Make a Emulated Android Device • Start eclipse • Windows -> AVD Manger • Opens a new window (maybe after a short delay) • Select new • Name: Test4 • Target: Google APIs API level 15 • SD Card Size: 1GiB • Snapshot Enabled • Level screen as default • Click “Create AVD” • Click on the device you just made and click on start • It can take sometime to start. Be patient • You should see the emulator in the eclipse DDMS fairly quickly, even as the device is booting up
