CN1中的LocalNofication声音

Question

Neither on Android nor on iOS the sound file referenced by a LocalNotification instance is played (check the sample code below). On Android the system's standard sound is played. Anyone knows what I am doing wrong here?

@Override
protected void postMain(Form f) {

    Container contentPane = f.getContentPane();
    contentPane.setLayout(new BorderLayout(BorderLayout.CENTER_BEHAVIOR_CENTER_ABSOLUTE));
    contentPane.setUIID("ToastBar");

    Button btn = new Button("create Notification");
    btn.addActionListener((e) -> {
        scheduleNotification(Display.getInstance(), 0, "Title", "Body", "notification_sound_file.mp3", System.currentTimeMillis() + 1000);
    });

    contentPane.add(BorderLayout.CENTER, btn);
}

private void scheduleNotification(Display dsp, int nId, String nTitle, String nBody, String soundFileName, long scheduleTime) {

    LocalNotification ntf = new LocalNotification();
    ntf.setId(nId + " " + scheduleTime);
    ntf.setAlertTitle(nTitle);
    ntf.setAlertBody(nBody + " " + scheduleTime);
    ntf.setAlertSound("/" + soundFileName);
    Log.p("scheduling ntf ("+nTitle+","+ ntf.getAlertBody() +","+ ntf.getAlertSound());
    dsp.scheduleLocalNotification(ntf, scheduleTime, LocalNotification.REPEAT_NONE);
}

Note: notification_sound_file.mp3 does exist in my default package!

Answer 1

If you want to get the sound file from device storage, then it can't detect directly Instead of using this

ntf.setAlertSound("/" + soundFileName);

Try this

ntf.setAlertSound(Environment.getExternalStorageDirectory().getAbsolutePath() + "Folder_Name/" + soundFileName);

This will locate your file and your specific sound will play. One more thing add "android.permission.READ_EXTERNAL_STORAGE" permission also in manifest. Best of luck.

Answer 2

The sound file needs to be a path to a file in FileSystemStorage which must always be fully qualified. You need to copy the file into the filesystem ideally under the app directory see https://www.codenameone.com/how-do-i-use-storage-file-system-sql.html
