A method is disclosed for handling an error in a script-based application, the method comprising detecting an error in the script-based application, the detecting comprising identifying the error and handling the detected error in accordance with a predetermined error-handling procedure suitable for the identified error.
摘要:
Methods and systems are provided for controlling asynchronous distribution and installation of software updates affecting applications installed on terminal devices of a wireless network. A versioning schema enforced by the application development environment enables the runtime environment of a terminal device to evaluate a software update to identify potential compatibility issues and control installation of the update.

A push proxy server for pushing data to a wireless device having a coverage state of online or offline. The push proxy server comprises a coverage state detector, memory, a data store, and a transceiver. The coverage state detector determines the coverage state of the wireless device. The memory stores a coverage state indicator for indicating the coverage state of the wireless device. The data store stores the data to be pushed to the wireless device when the coverage state indicator indicates the wireless device is offline. The transceiver transmits the data to the wireless device when the coverage state indicator indicates the wireless device is online. A method for implementing the push proxy server is also described.

Wireless data message optimization for messages sent between a wireless device and a server that provides a service that the wireless device is authorized to access is provided using an application gateway that serves as a proxy between the wireless device and the server. The application gateway maps optimized service request messages generated by the wireless device to a service request message format expected by the server, and maps response messages generated by the server to an optimized response message format expected by the wireless device. The optimized message format is flattened by removing unnecessary message structure, eliminates unnecessary message fields, and uses default and enumeration encoding to reduce optimized message size.

An improved handheld electronic device in conjunction with an improved holder for the handheld electronic device together form an improved electronic device. The handheld electronic device includes a first battery, and the holder includes a second battery and a charging apparatus. When the handheld electronic device and the holder are electrically connected together, such as when the handheld electronic device is received in a cavity formed in the holder and a plurality of first contacts on the handheld electronic device and a plurality of second contacts on the holder are electrically connected together, the charging apparatus charges the first battery on the handheld electronic device from the second battery on the holder.
摘要:
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.
