  1. To help get us all up to speed when it is time to install the SDK please make sure • Eclipse is installed (3.4 or higher) (32/64 bit all versions on CD) • A current JDK is installed (Linux rpm, or Windows on CD, Mac sorry) • You get a copy of the SDK installer (any OS) off one of the CDs being passed around (or the Jump Drive) • You can copy the android-sdk folder if you are on a windows machine (2.1-2.3 packages already) Introduction to Android Ross Hendrickson SSID: SolidStateDepot Pass: 2200Central

  2. What we hope to do today • Go through a 10,000 foot overview of Android • Talk about Mobile development • Talk about key parts of building an Android App • Get the SDK up • Get Eclipse talking with your device or a virtual one • Get everyone building a hello world app • If we get to it - a temperature converter app

  3. History • 2005 – Google Buys Android, Inc • 2007 – Open Handset alliance announced • 2008 – G1 Device released • 2009 – Cupcake, Donut, Éclair • 2010 – Android 2nd most sold

  4. Android Overview • Open Handset Alliance • Dozens of Manufacturers, Carriers, Software Companies • Comprehensive (all in one) • Developers, write once -> deploy to many devices • Users, massive level of customization (if so desired) • Entire OS Source Code available • Why do we care? Why should we care? • Why do manufacturers care?

  5. Advantages of Android • Linux • Portability • Security • 100 million devices May of 2011 • 550K activations daily Why do we care? Regardless of how the i-devices are doing Android is still a big player in the mobile arena

  6. Java Java and Android Java

  7. Native Libraries in Android • Native Libraries • Webkit • SQLite • Apache Harmony • OpenGL • OpenSSL

  8. So where are we?

  9. Important Android Building Blocks • Activities - Represents the presentation layer of an Android application, e.g. a screen which the user sees. An Android application can have several activities and it can be switched between them during runtime of the application. • Intents - are asynchronous messages which allow the application to request functionality from other services or activities. An application can call directly a service or activity (explicit intent) or ask the Android system for registered services and applications for an intent (implicit intents). 

  10. Blocks cont’d • Services - perform background tasks without providing an UI. They can notify the user via the notification framework in Android. • Content Provider - provides data to applications, via a content provider your application can share data with other applications. Android contains a SQLite DB which can serve as data provider • Broadcast Receiver - receives system messages and implicit intents, can be used to react to changed conditions in the system. An application can register as a broadcast receiver for certain events and can be started if such an event occurs.
