About the BlackBerry JDE

The BlackBerry® Java® Development Environment is a fully integrated development environment and

simulation tool for building Java 2 Platform, Micro Edition applications for Java-based BlackBerry® devices.

It is a Mobile Information Device Profile (MIDP) compliant J2ME™ environment for developers who wish to

maintain seamless portability in their wireless applications.

Use the BlackBerry JDE to build applications that take advantage of the unique features of the BlackBerry

device, such as desktop synchronization applications, GPS applications, and applications that push content

proactively to BlackBerry devices in environments that use the BlackBerry Enterprise Server. The

BlackBerry JDE provides ways for BlackBerry device applications to establish network connections to

servers on the Internet or the corporate intranet.

Each version of the BlackBerry JDE comes with the BlackBerry Smartphone Simulators that were available

when that version of the BlackBerry JDE was made public. You can download additional BlackBerry

Smartphone Simulators from the BlackBerry Developer Zone web site:

http://www.blackberry.com/developers/index.shtml.

A BlackBerry® device application can use the net.rim.device.api.ui.TouchEvent

class, the net.rim.device.api.ui.TouchGesture class, or both to support and

respond to touch screen input events such as taps, swipes, and gestures from a

BlackBerry device user.

Allow a MIDlet to

respond to touch

screen input.

A MIDlet can override the Canvas.pointerPressed(),

Canvas.pointerReleased(), and Canvas.pointerDragged() methods to respond

to touch screen input events.

A MIDlet can also override the public void touchEvent(TouchEvent message)

method in any of the BlackBerry® specific MIDP classes: BlackBerryCanvas,

BlackBerryGameCanvas and BlackBerryCustomItem,to respond to touch screen

input events.

Use the touch

screen keyboard. A BlackBerry® device application can use the

net.rim.device.api.ui.container.MainScreen.getVirtualKeyboard()

method with the methods of the net.rim.device.api.ui.VirtualKeyboard class to

display or hide the touch screen keyboard.

Use the touch screen keyboard APIs to allow a BlackBerry device application to make the

touch screen keyboard available to BlackBerry device users when they wish to provide

keyboard input.

Work with screen

orientation. A BlackBerry® device application can use the

net.rim.device.api.ui.Display.getOrientation() method to retrieve the

Known issues

This section lists known issues for the BlackBerry Java Development Environment (JDE) version 4.7.0.

APIs

Receiving event

notification from a

Player

A BlackBerry® device application that uses a

javax.microedition.media.PlayerListener for a

javax.microedition.media.Player does not receive events until the

javax.microedition.media.Player is in the STARTED state.

Impact: A BlackBerry device application may not be notified of certain

javax.microedition.media.Player events.

Workaround: To begin receiving events from the

javax.microedition.media.Player, put the

javax.microedition.media.Player in to the STARTED state.

Using the

Accessibility APIs The BlackBerry ® JDE version 4.7.0 does not support the Accessibility APIs. If you run

an application that uses the Accessibility APIs on the BlackBerry Storm device or in the

simulator for the BlackBerry® Storm device, an UnsupportedOperationException

is thrown.

BlackBerry

Storm simulator

Performing a

scrolling action. On the simulator for the BlackBerry® Storm device, scroll actions may not work as

expected.

Impact: You may not be able to perform scroll actions on the simulator for the

BlackBerry Storm device.

Workaround: Use the arrow keys on the computer keyboard to scroll in the Home

screen.

Simulating device

rotation in the

BlackBerry Storm

simulator

On the simulator for the BlackBerry® Storm device, when you simulate a rotation, the

following methods return data for the previous orientation:

•Channel.getLastAccelerationData(short[])

•AccelerometerData.getLastXAcceleration()

•AccelerometerData.getLastYAcceleration()

•AccelerometerData.getLastZAcceleration()

•AccelerometerData.getXAccHistory()

•AccelerometerData.getYAccHistory()

•AccelerometerData.getZAccHistory()

Impact: When you simulate a rotation, incorrect orientation readings will result.

Workaround: On the simulator for the BlackBerry Storm device, simulate the same

orientation or rotation event twice in a row.

Running the maps

sample application On the simulator for the BlackBerry® Storm device, if you run the BlackBerryMapsDemo

sample application, the BlackBerry Smartphone Simulator displays an error message if

8 of 8

you select the following options from the application menu:

•Invoke Location Document > View Single Location > View Map

•Invoke Location Document > View Multiple Locations > View Map

•Invoke Location Document > View Route > View Map

•Invoke Map View > View Map

Impact: You cannot view a map for a single location, multiple locations, a route, or view

a map using map view.

Workaround: None.

Running the

camera sample

application

On the simulator for the BlackBerry® Storm device, if you run the CameraDemo sample

application, the BlackBerry Smartphone Simulator displays an error message and stops

functioning.

Impact: You cannot successfully run the CameraDemo sample application on the

BlackBerry Storm Simulator.

Workaround: None.

Using the virtual

keyboard Screen classes only contain one method for the touch screen keyboard. The

getVirtualKeyboard() method returns a

net.rim.device.api.ui.VirtualKeyboard object that contains methods for

setting and getting the state of the virtual keyboard.

Launching a MIDlet

in the BlackBerry

Storm simulator

On the simulator for the BlackBerry® Storm device, when you launch a MIDlet that uses

commands of type SCREEN, the commands appear as Toolbar buttons on the bottom

of the screen.

Impact: MIDlet commands of type SCREEN display as Toolbar buttons on the screen of

a MIDlet.

Workaround: Commands of type ITEM.

Launching the

menu of a MIDlet On the simulator for the BlackBerry® Storm device, if you set the portrait keyboard to

the 12 key, you cannot open the menu in a MIDlet application.

Impact: You cannot open a menu in a MIDlet application if you have set the 12 key as

the portrait keyboard.

Workaround: Set a different key as the portrait keyboard.
