Player mp;

private void playmusic(String filename) throws MediaException, IOException {
mp = Manager.createPlayer("file:///" + filename);
mp.start();
}

public void hideNotify() {
if (mp != null) {
try {mp.stop();}
catch (MediaException ex) {}

Hi xins,

It was not clear on your post, i assume you're using Canvas and hideNotify(), obviously, but what about showNotify()?

"device error" exception"
Is there any further information about this error you could provide us?

Also, worth noting is that Game User Experience Library by this same FN has good tips about pauses in Games (single-player and Multi-player). See an excerpt below:

"An application should not change focus from one screen to another within the hideNotify() method (for example, Display.setCurrent(Displayable d)). In the Series 60 Platform, this causes focus to be regained by the game application. From the user’s point of view, it looks like pressing the End key or the Application key leads to the menu, which is not a desirable effect. It is recommended to use the Shownotify() method for regaining focus when changing display."

Hi kshirsagar,

While u r accepting a call, if u r using any players u should stop them. otherwise it will automatically get stopped. this is because for the phone the incoming call has more priority than the game. so it will stop all players and that resource will be used for the incoming call.

hi,

also try solution for restarting playback simply callin a method like that one:

void doPlay()
    {
 ...
         if (!initDone || player==null){
           initPlayer();
        }
        int state = player.getState();
        if (state == Player.CLOSED) {
        player.prefetch();
        } 
         else if (state == Player.UNREALIZED) {
        player.realize();
        
        } 
         else if (state == Player.REALIZED) {
        player.prefetch();
        }
        
        player.start();
 ...
}

called when form gains focus (showNotify()),
(taken from Nokia Java Developers Library),
