Elements and Performance Criteria

1. Define a platform
   • Determine target platform for the hand-held device
   • Choose and evaluate a development environment based on the target platform, hardware and mobile phone manufacturer on which the application will run
   • Prepare and configure the application development environment
2. Design user interface for a mobile application
   • Create views for different screen orientations and resolutions
   • Integrate appropriate navigation techniques
   • Design page layout and content
   • Integrate appropriate user input techniques
3. Permit the personalisation of parameters
   • Write code to allow users to configure application settings
   • Write code to allow users to configure application output, such as text size, brightness and sound effects
4. Build user interface for a mobile application
   • Itemise the required functionality
   • Build user interface in the determined development environment to fulfil this functionality
5. Connect to data sources
   • Bind controls to data sources
   • Persist data using eXtensible markup language (XML) serialisation
   • Access remote data using XML web services
6. Test and debug a mobile device application
   • Test application for overall functionality according to requirements
   • Iterate application design or build until test results meet requirements
7. Deploy a mobile device application
   • Create application packaging for deployment
   • Deploy an application to target devices

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package

Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Evidence of the ability to design build test and deploy applications for small devices mobile phones pocket PCs personal digital assistants PDAs enterprise digital assistants EDAs
Context of and specific resources for assessment	Assessment must ensure access to handheld devices or stimulators integrated development environment IDE internet and web services server system with sufficient privileges to deploy applications specific tools and licences depending on particular platform appropriate learning and assessment support when required modified equipment for people with special needs
Method of assessment	A range of assessment methods should be used to assess practical skills and knowledge The following example is appropriate for this unit verbal or written questioning to assess knowledge of mobile development environment
Guidance information for assessment	Holistic assessment with other units relevant to the industry sector workplace and job role is recommended where appropriate Assessment processes and techniques must be culturally appropriate and suitable to the communication skill level language literacy and numeracy capacity of the candidate and the work being performed Indigenous people and other people from a nonEnglish speaking background may need additional support In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge
