A.6.3 PausingAudioTest

This MIDlet exists to demonstrate how the J2ME Wireless Toolkit will warn you if a paused MIDlet has not stopped its running Players. After you launch the MIDlet, choose the Play command to start playing some audio. The screen displays a status, which is either “Well-behaved” or “Not Well-Behaved.”

Pause the MIDlet by choosing MIDlet > Pause from the emulator window’s menu. As expected, the MIDlet is paused and no message is displayed on the KToolbar console. Restart the MIDlet by choosing MIDlet > Resume from the emulator window’s menu.

Now choose the Misbehave command. Pause the MIDlet again. In the KToolbar console, you will receive a short lecture about how well-behaved MIDlets release resources when they are paused.

A.6.4 Video

The Video application illustrates how the emulator is capable of playing animated GIF files and capturing video. On a real device with a camera, video capture can be used to show the user what the camera sees.
