SMS发送状态广播接收器未在Oreo中运行

Question

我创建了2个广播接收器，一个获得SMS发送状态，另一个获得传送状态！每个都在清单文件中注册！直到nogout，一切都很好！现在在奥利奥接收器没有被调用！我发现Oreo有背景限制！我想知道我该如何解决这个问题！ 我的清单是：

 <receiver
            android:name="com.arafa.atlink.receiver">
            <intent-filter>
                <action android:name="SMS_SENT" />
            </intent-filter>
        </receiver>
        <receiver
            android:name="com.arafa.atlink.deliverreceiver">
            <intent-filter>
                <action android:name="SMS_DELIVERED" />
            </intent-filter>
        </receiver>

广播接收者：

public class receiver extends BroadcastReceiver {
    PreferenceHelper prefs;
    @Override
    public void onReceive(Context context, Intent intent) {
        String message = null;
        prefs = new PreferenceHelper(context);
        Log.e("DATA FROM BROADCAST", "++++++++++++++++++++++++++ SmsSentReceiver "+ intent.getExtras().getInt("ucode") +" +++++++++++++++++++++++++++++++++++++++++");
        switch (getResultCode()) {
            case Activity.RESULT_OK:
                message = "Message sent for "+intent.getExtras().getInt("ucode");
                Log.e("DATA", message);
                pingserversend(intent.getExtras().getInt("ucode"),"Send");
                break;
            case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                message = "Error. Message not sent.";
                Log.e("DATA", message);
                pingserversend(intent.getExtras().getInt("ucode"),"Failed");
                break;
            case SmsManager.RESULT_ERROR_NO_SERVICE:
                message = "Error: No service.";
                Log.e("DATA", message);
                pingserversend(intent.getExtras().getInt("ucode"),"no-service");
                break;
            case SmsManager.RESULT_ERROR_NULL_PDU:
                message = "Error: Null PDU.";
                Log.e("DATA", message);
                pingserversend(intent.getExtras().getInt("ucode"),"null-pdo");
                break;
            case SmsManager.RESULT_ERROR_RADIO_OFF:
                message = "Error: Radio off.";
                Log.e("DATA", message);
                pingserversend(intent.getExtras().getInt("ucode"),"radio-off");
                break;
        }
    }
}

正在广播：

   Intent intentSent = new Intent(Constants.SMS_SENT);
            intentSent.putExtra("ucode", ucode);
            PendingIntent piSend = PendingIntent.getBroadcast(this, ucode, intentSent, PendingIntent.FLAG_ONE_SHOT);
