Elements and Performance Criteria

1. Work effectively on the target platform
   • Review the requirements
   • Establish the platform
   • Install the required development tools, and environment
   • Use the available debugging tools and techniques
   • Deploy the completed applications on the target device, and for public download
   • Test the application using an emulator
2. Develop an application for a multi-touch device
   • Design and code the application, responding to events
   • Design and code the application, responding to taps, touches and gestures
   • Use a model view controller to design the approach
   • Develop the application, making effective use of auto-rotation and auto-resizing facilities
3. Develop the code using features of the mobile device
   • List the available features of the mobile device
   • Write code requiring web connectivity, and using web services
   • Write code that communicates with another device, using a communication protocol
   • Write code using an application programming interface (API) related to at least one other advanced device feature
4. Use available data persistence facilities
   • Write code, to read and write, to the devices file system
   • Use synchronisation techniques to synchronise data between the device and external data sources
   • Write code to make use of available database facilities, on the chosen device
5. Develop applications that are secure and stable
   • Determine and apply the performance objectives
   • Ensure memory management, using tools and techniques effectively
   • Use tools and techniques to evaluate performance
   • Eliminate zombies, using appropriate tools and techniques

Performance Evidence

Evidence of the ability to:

design applications for small devices that allow multi-touch user input and have advanced mobile features

build and test these applications

deploy these applications onto mobile devices.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
