Support for high-performance graphics by using OpenGL ES

You can create 2-D and 3-D graphics for your BlackBerry® device applications by using JSR 239 and BlackBerry APIs. JSR 239

contains the Java® binding for OpenGL® ES. OpenGL ES is used to create graphics that are displayed on wireless devices.

The following packages provide support for OpenGL ES:

• net.rim.device.api.math

• net.rim.device.api.opengles

• javax.microedition.khronos.egl

• javax.microedition.khronos.opengles

• java.nio

For more information about OpenGL ES, visit www.khronos.org/opengles/. For more information about support for OpenGL ES

in BlackBerry device applications, see the BlackBerry Java Application Multimedia Guide and the API reference for the

BlackBerry® Java® Development Environment.

Video capture

You can use the camera application on the BlackBerry® device to record videos by using JSR 135 and the Manager class that is

provided in the javax.microedition.media and javax.microedition.media.control packages. For example,

you can create an application that records videos and manages the viewfinder of the camera application.

You can record the video to a .3GP file on the BlackBerry device or record the video to an output stream. Data is written to the

output stream in a proprietary format.

To download a sample application that demonstrates how to record a video, visit www.blackberry.com/go/

videorecordingsample. For more information about video recording, see the BlackBerry Java Application Multimedia

Development Guide and the API reference for the BlackBerry® Java® Development Environment.

Personal Information Management

Multiple contact lists support

Your BlackBerry® device application can access multiple contact lists on a BlackBerry device by using the PIM class that is

provided in the javax.microedition.pim package. For example, your application can access the contact list in the contacts

application on the BlackBerry device, and the contact list in other applications on the BlackBerry device.
