System and method for building wireless applications

Abstract

A system and method is described for effective management of a User Interface (UI) of a wireless device by implementing direct mapping between the application data domain and UI screens and controls. The device has an intelligent wireless device runtime environment (Device Runtime) that provides a set of basic services to manage the wireless application, including a series of linked screen and data component definitions, and their interactions can simplify the development effort and reduce resource allocation. The data domain for this category of applications is defined using the atomic data component definitions. The communication between a device user interface and data components is defined using atomic screen component definitions. Both screen and data component definitions are described in metadata using a structured definition language such as XML. The relationships between the screen and data component definitions are embedded in the XML definitions in the form of screen/data mappings. Typically, rendered screens for display are derived from some underlying data component and screens controls affected by user events impact the current state (or data representation) of the application Changes to the application domain data are automatically synchronized with the user interface, and user-entered data is automatically reflected in the application domain data. The primary mechanism behind this synchronization is the mapping of screens and data. This mechanism enables creation of dynamic and interactive screens. All changes to the data component can be immediately reflected on the screen and vice versa. This model allows building effective wireless applications based on server-to-device notifications. The data updates asynchronously pushed from the server are instantaneously reflected at the UI screen.

Description

technical field [0001] The present application relates generally to the display of wireless applications on user interfaces of wireless devices. Background technique [0002] Today, the number of terminal devices in use continues to increase, such as mobile phones, PDAs with wireless communication capabilities, two-way pagers, and the like. Software applications running on these devices increase their functionality. For example, a mobile phone may include an application that retrieves city-wide weather, or a PDA may include an application that allows the user to shop for groceries. These software applications utilize connectivity to the network in order to provide timely and useful services to users. However, developing software applications for multiple devices remains a difficult and time-consuming task due to the constrained resources of some devices and the complexity of communicating large amounts of data to the devices. [0003] Currently, devices are configured to ...

However, native applications have the disadvantages of being non-platform independent, having to develop multiple versions of the same application, and being relatively large in size, which places a severe burden on the device's memory resources
