我在我的应用中使用推送通知。当应用程序正在运行或处于前台状态时它正常工作。但是当用户从任务管理器/选项卡清除应用程序时,通知不会到来。我尝试了很多方法,如包重启和所有。但我无法得到解决方案。如果有人知道我做错了什么。请告诉我。

这是我的GcmBroadcastReceiver类: -

public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent)
    {        ComponentName comp = new ComponentName(context.getPackageName(),
            GcmIntentService.class.getName());
        startWakefulService(context, (intent.setComponent(comp)));
        setResultCode(Activity.RESULT_OK);
    }
}  

这是我发送通知的GcmIntentService类: -

public class GcmIntentService extends IntentService {

    public static final int NOTIFICATION_ID = 1;
    private NotificationManager mNotificationManager;
    private final static String TAG = "GcmIntentService";
    private Context mContext;


    public GcmIntentService() {
        super("GcmIntentService");
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        Bundle extras = intent.getExtras();
        Log.d(TAG, "Notification Data Json :" + extras.getString("message"));

        GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
        String messageType = gcm.getMessageType(intent);

        if (!extras.isEmpty()) {
            if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR
                    .equals(messageType)) {
                sendNotification("Send error: " + extras.toString());

            } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED
                    .equals(messageType)) {
                sendNotification("Deleted messages on server: " + extras.toString());

            } else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE
                    .equals(messageType)) {
                // This loop represents the service doing some work.
                for (int i = 0; i < 5; i++) {
                    Log.d(TAG, " Working... " + (i + 1) + "/5 @ "
                            + SystemClock.elapsedRealtime());
                    try {
                        Thread.sleep(5000);
                    } catch (InterruptedException e) {
                        e.printStackTrace();

                    }
                }
                Log.i(TAG, "Completed work @ " + SystemClock.elapsedRealtime());
                sendNotification(extras.getString("message"));
            }
        }        // Release the wake lock provided by the WakefulBroadcastReceiver.
        GcmBroadcastReceiver.completeWakefulIntent(intent);
    }     // Put the message into a notification and post it.


    private void sendNotification(String msg) {

        mNotificationManager = (NotificationManager) this
                .getSystemService(Context.NOTIFICATION_SERVICE);


        Intent intent = new Intent(this, MainActivity.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);
        intent.putExtra("KEY","aman");


        PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);


        NotificationCompat.Builder mBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
                .setSmallIcon(android.R.drawable.sym_def_app_icon)
                .setContentTitle("Telepoh")
                .setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
                .setContentText(msg)
                .setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE);

        mBuilder.setContentIntent(contentIntent);
        mBuilder.getNotification().flags |= Notification.FLAG_AUTO_CANCEL;
        mBuilder.setAutoCancel(true);


        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
    }

    private int getNotificationIcon() {
        boolean useWhiteIcon = (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP);
        return useWhiteIcon ? R.drawable.gcm : R.drawable.push_icon;
    }
}

当应用程序处于运行状态和前台状态时,推送通知正常工作。但我的问题是当应用程序从任务管理器清理然后通知没有来。我尝试重新启动包但它不起作用。如果有人知道我做错了那么请告诉我。
