  1. Cosc 5/4730 Information and Resources

  2. Java. • If you don't already have java SDK installed • http://java.sun.com • Get the Java SE SDK v7 (not v8 as of July) • Install it.

  3. Eclipse • http://www.eclipse.org/downloads • Download the Eclipse Standard (v4.4 is current) • The labs are using v4.3 Kepler • It's in a zip format. • Open it and extract to somewhere useful • c:\program files\ for example • create the short cuts on the desktop or in the start menu as you feel necessary

  4. Android SDK and plugin • Follow the directions on the page • http://developer.android.com/sdk/index.html • Following the directions for eclipse and installing the ADT plugin. • https://dl-ssl.google.com/android/eclipse/ • notes: • android SDK doesn't have an installer. It's a zip file, that then downloads the packages you need. • the setup for the SDk will download about 1GB+ of data, so it may take a while to complete. • With the setup of android SDK, you may need to go to settings and change it to force https://… before it works. • when installing the plugin for eclipse, https://… may fail. you can use http://… instead.

  5. Signing Keys • Eclipse creates a debug key for you, it is good for 1 year. For this class, that is all you will need. • A note, that is one different key on each machine you use. Which can cause you issues, so you can copy it around all the development environments you use. • C:\users\<username>\.android\debug.keystore and default.keysetfiles • If you plan to release you app to android market then you will need to get a real developer key.

  6. Department machines. • Windows • Eclipse and both SDKs are already installed • c:\phone is the directory where everything is stored, if eclipse does not automatically find it. • Linux • Eclipse 4.2.X is installed (cmd: eclipse) • Eclipse may not find the android sdk. • /usr/local/android-sdk-linux/ is the directory.

  7. Android • Remember, Android is the OS and not the hardware manufacture. • http://developer.samsung.com/develop for Samsung’s developer site. • http://www.motorola.com/ • http://developer.motorola.com/?WT.mc_id=us_mdc developers site. For android tools, click the SDK add-ons link. • http://www.htc.com/ • http://developer.htc.com/ with very limited developers, but you can get the some source code • Others: http://www.andro-phones.com/all-android-phones.php

  8. Android General info • While there are a lot of sites covering android, I’ve found http://www.androidcentral.com/ gives good coverage, forums, a lots of information and tutorials. • Includes information on “rooting” an android phone. • Remember Android is based on the linux kernel. • There seems to be a number of android app stores • Amazon: http://www.amazon.com/mobile-apps/b?node=2350149011 • and http://www.appbrain.com/ but I’ve never used this one.

  9. Android Emulators • Much of the code can be run on the emulators (but not all, we need the actual devices as well). • Read up on how to control the emulators, there is a ton of information. • http://developer.android.com/tools/devices/emulator.html

  10. Desktop software • Motorola and other provide desktop software to sync media files. • I haven’t seen anything that allows you to backup or “sync” with your computer. • The gmail account syncs your contacts and calendar with gmail.com. • There is backup software • JS backup will back the device and store the file local or in the cloud (such as dropbox). • Clockworld Recovery and Titanium can be used, but not free. • Some require that you root your phone.

  11. OTA app install • Using Cosc’s web servers • Howto create web pages: http://www.cs.uwyo.edu/policies/web.html • Create a .htaccess file • Add one or more of the following: • AddType application/vnd.android.package-archive .apk

  12. OTA app install (2) • Create a html file • Copy the apk file to web server and link to it • <a href="app.apk">app</a> • Android phone • Settings->Applications Settings • Check unknown sources • otherwise you can only install from the android market place.

  13. Android APIs • Developer pages have lot of examples and reference guides • api reference guide: http://developer.android.com/reference/android/app/package-summary.html • Resources and tutorials (where the helloworld example came from) • http://developer.android.com/resources/index.html • StackOverflow.com has numerous Q&A and examples as well. • I’ll try and reference the websites I use in the slides and examples.

  14. Android and Versions. https://developer.android.com/about/dashboards/index.html

  15. Android and Version (2) • There are some pretty major differences between 2.3.X (we are skipping 2.2 and 3.X Honeycomb) and 4.X • There are also differences between 4.0 (ics), 4.1, 4.2, 4.3 (jelly Bean), and 4.4 (Kitkat) • And huge difference in Android L (at the time of the preview). • I’m going to teach relatively current material with the support libraries so we use the new APIs (with minor differences) on 2.3.3+ • Not everything will look the same, but it will function similarly.

  16. Android and Version (3) • Lastly, Android is a moving target • You will need to keep in mind what version you are compiling too • The support library is updated (randomly) as well to fix errors and there is not necessary an announcement. • At some point during the semester the final edition of “Android L” will come out (LemonHead, Lemon Drops and Licorice are guesses for the what the L standards for). • Last year, android discounted the map API (and associated necessary keys) during the semester.

  17. My First Android Project • In Eclipse, Select Android > Android Application Project, and click Next. • Enter the settings for your application, including Application Name, Project Name, Package Name, API level settings and presentation Theme, and click Next. • Enter the project configuration options, and click Next. • Optionally enter launcher icon settings, and click Next. • In the Create Activity page, select an application template to use. • What are the templates you ask? • https://developer.android.com/tools/projects/templates.html

  18. My First Android Project (2) • Depending on the selected template a lot of code maybe written for you, Now: • Edit the res/layout/activity_main.xml and add Widgets as needed. • You may want to change the layout from a Relative to LinearLayout (Vertical) • In the activity/fragment add java code to control you widgets.
