MEID retrieval

An MEID is a unique ID that identifies a mobile device that operates on a CDMA network. A BlackBerry® device that operates

on a CDMA network has an MEID. You can retrieve the MEID by using the CDMAInfo.getHexMEID() and

CDMAInfo.getDecimalMEID() methods that are provided in the net.rim.device.api.system package.

For more information about retrieving an MEID, see the API reference for the BlackBerry® Java® Development Environment.

Support for the BlackBerry Push Service on a BlackBerry device

You can implement the features of the BlackBerry® Push Service SDK on a BlackBerry device by using the Push API that is

provided in the net.rim.blackberry.api.push package. The Push API enables you to create a push application that can

perform the following functions:

• register your application with the BlackBerry® Push Service

• listen for push notifications sent to the BlackBerry device

• start your application when the BlackBerry device receives a push notification from your application

• send a notification after a specified event occurs on the BlackBerry device (for example, after a user changes the SIM card

in the BlackBerry device)

• send a notification when a user removes your application from the BlackBerry device

For more information about the BlackBerry Push Service, visit www.blackberry.com/developers/pushservice. For more information

about the Push API, see the API reference for the BlackBerry® Java® Development Environment.

JavaScript extensions for a BlackBerry Widget application

You can register your own JavaScript® extensions with your BlackBerry® Widget application by using the

WidgetExtension interface that is provided in the net.rim.device.api.web package. For example, you can create

your own JavaScript extension that can expose BlackBerry device capabilities that the BlackBerry Widget API does not expose.

For more information about developing a BlackBerry Widget application, see the BlackBerry Widget SDK Development Guide,

the API reference for the BlackBerry® Widget SDK, and the API reference for the BlackBerry® Java® Development Environment.

SQLite

You can create an application that uses the SQLite® database library that is available on a BlackBerry® device. SQLite is an open

source relational database library. BlackBerry devices that run BlackBerry® Device Software 5.0 or later include the SQLite library.
