在我的应用程序中，我必须在收到通知时播放声音。为了播放音频，我实现了以下代码：

private static final short BFlat = 466;   //466.16
private static final short AFlat = 415;     //415.30
private static final short A = 440; //440.00
private static final short GFlat = 370;     //369.99
private static final short DFlat = 554;     //554.37
private static final short C = 523; //523.25
private static final short F = 349; //349.32
// Duration of a 16th note, arbitrary, in ms.
private static final short TEMPO = 125;

// Duration of a 16th note, arbitrary, in ms.
private static final short d16 = 1 * TEMPO;

// Duration of an eighth note, arbitrary, in ms.
private static final short d8 = d16 << 1;
// 10 ms pause.
private static final short dpause = 10;

// Zero frequency pause.
private static final short pause = 0;

private static final short[] TUNE = new short[] {
             BFlat, d16, pause, dpause,
             BFlat, d16, pause, dpause,
             BFlat, d16, pause, dpause,
             BFlat, d16, pause, dpause,
             A, d16, pause, dpause,
             BFlat, d16, pause, dpause,
             GFlat, d16, pause, dpause,
             GFlat, d16, pause, dpause,
             A, d16, pause, dpause,
             BFlat, d16, pause, dpause,
             DFlat, d16, pause, dpause,
             C, d16, pause, dpause, //bar 1
             AFlat, d16, pause, dpause,
             AFlat, d16, pause, dpause,
             AFlat, d16, pause, dpause,
             AFlat, d16, pause, dpause,
             F, d16, pause, dpause,
             GFlat, d16, pause, dpause,
             AFlat, d16, pause, dpause,
             BFlat, d16, pause, dpause,
             AFlat, d16, pause, dpause,
             F, d8 + d16 //bar 2
         };

public MyScreen()
{        
    // Set the displayed title of the screen       
    setTitle("MyTitle");
    // % volume
    final int VOLUME = 80;


    if ( Alert.isAudioSupported())
    {
         System.out.println("------alert is audio supported-------------"+ Alert.isAudioSupported());

         Alert.startAudio(TUNE, 100);
        //Alert.startVibrate(5000);
    }

Alert.startAudio()根本没有播放声音。但我可以振动手机。请让我知道我在哪里遗漏了什么或如何在 startAudio 中使用短数组。请给我一些建议或任何想法。谢谢

try{
                     Application.getApplication().invokeAndWait(new Runnable() {
                         public void run() 
                         {

                         }
                     });
                       final Dialog screen = new Dialog(Dialog.D_OK_CANCEL, " "+text,
                                Dialog.OK,
                                //mImageGreen.getBitmap(),
                                null, Manager.VERTICAL_SCROLL);
                        final UiEngine ui = Ui.getUiEngine();
                        Application.getApplication().invokeAndWait(new Runnable() {
                            public void run() {
                                NotificationsManager.triggerImmediateEvent(0x749cb23a76c66e2dL, 0, null, null);
                                ui.pushGlobalScreen(screen, 0, UiEngine.GLOBAL_QUEUE);
                            }
                        });
                        System.out.println("-----IN PUSH MESSAGE READER----"+screen.getSelectedValue());
                        if(screen.getSelectedValue()==1)
                        {
                            System.out.println("-----I1-"+screen.getSelectedValue());

                            ApplicationDescriptor[] appDescriptors =CodeModuleManager.getApplicationDescriptors(CodeModuleManager.getModuleHandle("BB_push"));
                          ApplicationDescriptor appDescriptor = new ApplicationDescriptor(appDescriptors[0], new String[] {"BB_push"});
                          try {
                            ApplicationManager.getApplicationManager().runApplication(appDescriptor);
                          }catch (ApplicationManagerException e) 
                          {
                            // TODO Auto-generated catch block
                            System.out.println("in notification exception----"+e);
                            e.printStackTrace();
                        }
                        }

                      //  screen.setDialogClosedListener(new MyDialogClosedListener());
                        }
                        catch (Exception e) {
                        }

我想在单击确定按钮时打开应用程序，但它不起作用。

Have you considered using the Notification API? This way, the user would be able to setup your app's notification sound, and have it change appropriately when the notification profile is changed from the home screen - think "Normal" "Vibrate Only" and "All Alerts Off"

Take a look at NotificationsManager and the methods triggerImmediateEvent and registerSource
