Implementation Deliverable Ø Ø Source Code Ø Binary Code Ø Deadline: Nov. 10 th Ø Ø Note: unit test cases should be included in implementation Presentation & Demo: Nov. 17 th and Nov. 19 th

Implementation Presentation Ø Ø All people should present part of their work Ø Talk about problems met during development Ø run major features of the app

Testing & Documentation Testing Ø Ø System testing Ø Test cases and results Documentation Ø Ø Ø Test documents Ø API documents (using Javadoc) Ø User guide Deadline: Nov. 20 th

Evaluation Ø Project quality Ø Documentation Ø Process quality Ø Presentation Ø Teamwork & work assignments

Project quality Evaluation base: code Ø Ø Whether all features implemented Ø Bugs found Ø Coding style Ø Comments Ø Unit test case quality

Documentation Quality Evaluation base: documents Ø Ø Specification, design documents, API documents, test documents, user guide Ø Correctness Ø Whether go into details Ø Whether well structured

Process Quality Evaluation base: version-control system commits Ø Ø You must use a version control system: SVN or Git are recommended, add me as a user Ø Reasonable progress Ø Size of code commit Ø Maturity of commit

Presentation Evaluation base: demo & presentation Ø Ø Show understanding of the project Ø Demo goes smoothly

Teamwork Evaluation base: email record, svn commits, work assignments Ø Ø Balanced workload Ø Interactions in email record and svn commits

Today’s class Ø Ø 31 Projects Ø Process and Evaluation Ø Requirements Ø Calendar Ø SMS Messenger Ø Contact Manager Ø Book Shelf Android Development I Ø Android system & Emulator Ø Environment Setup

Android Development I Ø History of android Ø An open source mobile operating system Ø Oct 2003: Palo Alto Ø Andy ØA digital camera system at beginning Ø Aug Ø Oct. 2005: acquired by Google 2008: HTC dream, the first android phone Ø Most Ø 1 Rubin, and 3 other colleagues popular mobile system (market share 50%+) million plus apps

Android Development I Ø Introduction to Android Ø Based on Linux system Ø The programming language is Java Ø Jar files are transformed to app Ø Apps are installed to the system, and then executed on the Dalvik virtual machine Ø Dalvik VM: a variant of JVM Ø Why? Smaller code size.

Android Development I

Android stock apps Ø Also called built-in apps Ø Apps included in the android system / sdk Ø Like IE in windows Ø Including: phone, sms messenger, contact manager, web browser, clock, etc.

Emulator Ø Ø People do not want to develop software using mobile device directly, why? Ø Too slow Ø Hardware incompatibilities Ø Handling of multiple devices Emulator Ø A virtual android mobile phone running on the host machine

Emulator looks like…

Emulator Ø Simulates almost everything about a mobile phone Ø Run apps Ø Time Ø Make/receive phone calls, send/receive messages Ø Phone rotation Ø Battery level, AC on / off Ø GPS locations Ø Audio recording

Emulator Ø Something it currently cannot do Ø Take pictures / record video (Just have it with web camera) Ø Ø Most Sensors Other Positions (except for portrait and landscape) Ø Light Ø Phone specific devices, such as infrared emitter

Interactions between emulator and your host system Ø Ø The emulator can access internet Adb tool set to transfer data between the emulator and the host system Telnet to 5554 to control the emulator (providing a shell of the emulator) Emulators can interact with each other

Android Development Ø Download Android Studio Ø https: //developer. android. com/sdk/index. html Ø Extract the zip file Ø Start

Create An Android project Ø Go to new project Ø Select Android Ø Input a name for you project Ø Click next for all steps

Create a new virtual device Ø Go to virtual device manager Ø Add a device Ø Give a name to the virtual device Ø Select memory, SD card, etc.

Compile and Run Ø Create the hello world android project Ø Run as an android project Ø Ø Wait for the system to start and go to the app hello world And that’s it!
