Two ways of creating Custom Blackberry Applications

1) using Java Development Environment ( JDE )
2) using Eclipse

Java Development Environment-JDE

The BlackBerry JDE provides a complete set of APIs and tools that you can use to develop custom Java applications. Standard BlackBerry applications for these handhelds are written in Java, so you can create

Overview of CLDC Generic Connection Framework

The java.io.* and java.net.* packages of J2SE require much more memory than many hand-held wireless devices can afford. In addition, the following requirements for various communication mechanisms call for the design of a new set of abstractions that can be used at the programming level:
� Device manufacturers that work with circuit-switched networks require stream-based connections such as the Transport Control Protocol (TCP), a connection-oriented protocol.
Mobile Media APIs in J2ME

- The Mobile Media API (MMAPI) is an optional package that supports multimedia applications on J2ME-enabled devices.
- This standard Java specification, defined by the Java Community Process (JCP) is JSR 135, is highly flexible.
- It has been designed to run with any protocol and format; for example, it doesn't specify that the implementation must support particular transport protocols such as HTTP or Real-Time Transport Protocol (RTP), or media formats such as MP3, MIDI, or MPEG-4
There are two parts to
Record Management Store API in J2ME

What are records?

Record Management System (RMS), an application programming interface (API) gives MIDP applications local, on-device data persistence.
RMS is a system for managing records. A record is an individual data item. RMS places no restrictions on what goes into a record: a record can contain a number, a string, an array, an image -- anything that a sequence of bytes can represent. If you can create a binary encoding of your data -- and a corresponding decoding -- then you can store it in a record, subject of course

Location Based API in J2ME

Location-based services (LBS) provide users of mobile devices personalized services tailored to their current location.

They open a new market for developers, cellular network operators, and service providers to develop and deploy value-added services: advising users of current traffic conditions, supplying routing information, helping them find nearby restaurants, and many more.

What Location-Based Services Do
Location-based services answer three questions:
