Android GCM notification Builder功能在应用程序关闭时不工作

android push-notification

Android GCM notification Builder功能在应用程序关闭时不工作,android,push-notification,google-cloud-messaging,Android,Push Notification,Google Cloud Messaging,我创建了一个正确接收GCM通知的应用程序。当我打开应用程序时，通知会响起来，并且通知会像下面代码中定义的一个大盒子一样发出： NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.mipmap.ic_launcher) // .setLargeIcon(imageBitmap)

我创建了一个正确接收GCM通知的应用程序。当我打开应用程序时，通知会响起来，并且通知会像下面代码中定义的一个大盒子一样发出：

 NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.ic_launcher)
            //    .setLargeIcon(imageBitmap)
                .setTicker("CheGroup")
                .setContentTitle(title)
                .setContentText(message)
                .setAutoCancel(true)
                .setDefaults(Notification.DEFAULT_ALL)
                .setContentIntent(pendingIntent)
                .setStyle(new NotificationCompat.BigTextStyle()
                        .bigText(message));

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

        notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
即使应用程序已关闭或手机已锁定，但手机未振动/响铃，也会发出通知。此外，通知仅显示为单行框（不具有定义的BigTextStyle），因此无法读取通知消息的一部分。因此，NotificationCompat.Builder中定义的功能只有在应用程序打开时才起作用。我的问题是如何在应用程序关闭时发出通知，并使其以BigTextStyle显示。请注意，这些设置在应用程序打开时正常工作

将其置于接收状态

ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
    List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(1);
    ComponentName componentInfo = taskInfo.get(0).topActivity;
    if(componentInfo.getPackageName().equalsIgnoreCase("com.example.myapp")){

        updateMyActivity(message);  //send broadcast to notify app



        //Activity Running
//            Send a broadcast with the intent-filter which you register in your activity
//            where you want to have the updates
        }
        else{
            //Activity Not Running
            //Generate Notification
            sendNotification(message);
        }

ActivityManager am=（ActivityManager）getSystemService（ACTIVITY_服务）；
List taskInfo=am.getRunningTasks（1）；
ComponentName componentInfo=taskInfo.get（0）.topActivity；
if（componentInfo.getPackageName（）.equalsIgnoreCase（“com.example.myapp”））{
updateMyActivity（message）；//发送广播以通知应用程序
//活动运行
//发送带有您在活动中注册的意图过滤器的广播
//您希望在哪里进行更新
}
否则{

//生成通知
发送通知（消息）；
}
并调用此方法

        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

        /*PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 *//* Request code *//*, intent,
                PendingIntent.FLAG_ONE_SHOT);*/

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        if (android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {

                    .setSound(defaultSoundUri)
                    .setContentIntent(pendingIntent);


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

            notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
        }
        else
        {

            NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)

                    .setContentTitle("hey..! your booking is confirmed")

        }
    }

private void sendNotification（字符串消息）{
Intent Intent=新Intent（这是FullMapActivity.class）；
intent.addFlags（intent.FLAG\u ACTIVITY\u CLEAR\u TOP）；
//int color=getResources（）.getColor（R.color.my\u notif\u color）；
PendingEvent PendingEvent=PendingEvent.getActivity（this，0，intent，PendingEvent.FLAG_UPDATE_CURRENT）；

悬挂式帐篷（一杆旗帜）*/
Uri defaultSoundUri=RingtoneManager.getDefaultUri（RingtoneManager.TYPE_通知）；
if（android.os.Build.VERSION.SDK_INT
当代码在“else”中重复时，为什么还需要“if（android.os.Build.VERSION.SDK_INT
