Question

我想在我的应用中实现通知。我的代码在下面，并且工作正常，它会显示通知，但每当通知到达应用程序崩溃时。我不知道为什么会这样？

NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);

   Bitmap largeIcon = BitmapFactory.decodeResource(context.getResources(), R.drawable.logo);
   Intent notificationIntent;
   notificationIntent = new Intent(context, Login.class);
   PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);

   Notification noti = new NotificationCompat.Builder(context)
                    .setTicker("ticker message")
                    .setLargeIcon(largeIcon)
                    .setWhen(System.currentTimeMillis())
                    .setContentTitle("title")
                    .setContentText("message")
                    .setContentIntent(contentIntent)
                    //At most three action buttons can be added
                    .setAutoCancel(true).build();

                  //noti.number=++count;
                //noti.when=System.currentTimeMillis();
                noti.flags |= Notification.FLAG_ONLY_ALERT_ONCE;
                noti.flags |= Notification.FLAG_AUTO_CANCEL;
                 // Play default notification sound
                noti.defaults |= Notification.DEFAULT_SOUND;
                noti.defaults|=Notification.DEFAULT_LIGHTS;

                // Vibrate if vibrate is enabled
                noti.defaults |= Notification.DEFAULT_VIBRATE;
                //Show the notification
                notificationManager.notify(notifyID, noti);

请有人帮助我！

我不确定这一点，但在VIBRATE l中添加manifest.xm权限并尝试

<uses-permission android:name="android.permission.VIBRATE" />

并就此给我反馈。

只需做以下事情，

     Intent notificationIntent;
        notificationIntent = new Intent(context, Login.class);
        //add setFlags
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        PendingIntent contentIntent = PendingIntent.getActivity(context, 0,                                                                                                                                                                                                                                                                                                   notificationIntent, 0);

   Notification noti = new NotificationCompat.Builder(context)
                    .setTicker("ticker message")
                    .setLargeIcon(largeIcon)
                    .setWhen(System.currentTimeMillis())
                    .setContentTitle("title")
                    .setContentText("message")
                    .setContentIntent(contentIntent)
                   .build();
   NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
                // hide the notification after its selected

                noti.flags |= Notification.FLAG_AUTO_CANCEL;
                noti.defaults |= Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE;

                noti.defaults|=Notification.DEFAULT_LIGHTS;
                notificationManager.notify(0, noti);

同时在androidmanifest.xml中授予权限：

  <uses-permission android:name="android.permission.VIBRATE" />

当通知到来时，我的应用程序崩溃了
