如何设置接收器在没有前台服务的情况下关闭应用程序时获取交付报告，我的应用程序设置为默认短信应用程序

问题描述

我在我的默认 SMS 应用程序中使用前台服务，但我注意到其他应用程序不使用该服务，但即使应用程序未打开仍然可以获取交付报告，想知道这些应用程序是如何工作的。

我正在使用下面的代码来接收发送和交付报告，非常欢迎任何见解！

我一直在拼命寻找答案，找了很长时间，但没有得到解决方案。

public class SendMySMS extends Service {

int count = 0;

public static final String PRIMARY_NOTIF_CHANNEL = "default";
public static final int PRIMARY_FOREGROUND_NOTIF_SERVICE_ID = 1009;

broadcastReceiver sendReceiver;
broadcastReceiver deliveryReceiver;

@Override
public IBinder onBind(Intent intent) {
    return null;
}

@Override
public int onStartCommand(Intent intent,int flags,int startId) {
    super.onStartCommand(intent,flags,startId);
    Log.d(TAG4,"SendMySMS service started");
    if (intent!=null) {
        String str_number = intent.getStringExtra("KEY_number");
        String str_body = intent.getStringExtra("KEY_body");
        String str_subId = intent.getStringExtra("KEY_sub_id");

        if (str_number!=null && str_body!=null && str_subId!=null && !str_number.equals("") && !str_body.equals("") && !str_subId.equals("")) {
            count++;
            sendSMS(str_number,str_body,str_subId);
        }else{
            Toast.makeText(getBaseContext(),"Could't send sms",Toast.LENGTH_LONG).show();
        }
    }
    return START_STICKY;
}

@Override
public void onCreate() {
    super.onCreate();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        notificationmanager notificationmanager = (notificationmanager) getSystemService(Context.NOTIFICATION_SERVICE);
        NotificationChannel chan1 = new NotificationChannel(PRIMARY_NOTIF_CHANNEL,"Background",notificationmanager.IMPORTANCE_NONE);
        chan1.setLightColor(Color.TRANSPARENT);
        chan1.setLockscreenVisibility(Notification.VISIBILITY_SECRET);
        notificationmanager.createNotificationChannel(chan1);

        Intent intent1 = new Intent(this,MainActivity.class);
        intent1.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this,intent1,PendingIntent.FLAG_UPDATE_CURRENT);

        Notification notification = new NotificationCompat.Builder(this,PRIMARY_NOTIF_CHANNEL)
                .setSmallIcon(R.drawable.ic_sms_notif)
                .setContentTitle("Waiting for delivery report..")
                .setPriority(NotificationCompat.PRIORITY_MIN)

    }
}
