使用4G网络发送短信后，广播接收器不接收意图

Question

我没有收到使用4G网络的BroadcastReceiver的意图。我使用以下代码来接收短信发送结果的代码。我在2G蜂窝网络中获得了当前的结果，但没有获得4G 如果有任何机构有想法请回复。
谢谢。

registerReceiver(sendBroadcastReceiver, new IntentFilter("SENT"));
sendBroadcastReceiver = new BroadcastReceiver()
{
    int result = getResultCode();
    @Override
    public void onReceive(Context context, Intent intent)
    {
        switch (result)
        {
            case Activity.RESULT_OK:
                System.out.println("Received response");
                break;  
            case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                addFailedResultsInList("RESULT_ERROR_GENERIC_FAILURE");
                break;
            case SmsManager.RESULT_ERROR_NO_SERVICE:
                addFailedResultsInList("RESULT_ERROR_NO_SERVICE");
                break;
            case SmsManager.RESULT_ERROR_NULL_PDU:
                addFailedResultsInList("RESULT_ERROR_NULL_PDU");
                break;
            case SmsManager.RESULT_ERROR_RADIO_OFF:
                addFailedResultsInList("RESULT_ERROR_RADIO_OFF");
                break;

        }
    }
};

Answer 1

除了创建BroadcastReceiver之外，您还需要为要获取的事件注册它。您可能想要学习本教程 http://www.vogella.com/articles/AndroidBroadcastReceiver/article.html

当您想收到有关短信接收的通知时，您需要注册活动

android.provider.Telephony.SMS_RECEIVED

并请求权限     http://developer.android.com/reference/android/Manifest.permission.html#RECEIVE_SMS

sendBroadcastReceiver = new BroadcastReceiver()
{
    @Override
    public void onReceive(Context context, Intent intent)
    {

        result = getResultCode (); //<-------------------

        switch (result)
        {
            case Activity.RESULT_OK:
                System.out.println("Received response");
                break;  
            case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                addFailedResultsInList("RESULT_ERROR_GENERIC_FAILURE");
                break;
