The commands may or may not be available depending on the media type that
Simple Player is playing. In addition, some commands can be invoked using the
keypad buttons. The following table describes the availability of commands, their
keypad equivalents, and the relevant class from MMAPI.
Note that a short list of commands and the corresponding keypad buttons is
available in the Simple Player application itself. Just choose the Quick Help
command from the menu.
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
Player s. 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.
Loop Mode Plays back the audio file immediately after completion of play.
Running Loopmode once plays the audio file once. Pressing a
second time plays the file three times. Pressing a third time
plays the file repeatedly. Pressing a fourth time returns to single
play.
Skip 1 and
3 Skips forward or backward five percent of the duration of the
media file. The sound track syncs to the video.
Rewind Returns to the start time of the audio playback.
Stop and
Rewind 5 Stops plaback and rewinds to the start time.
Quick Help Displays a list of commands and keypad buttons.
