android - 通过 BroadcastReceiver 的短信接收器

Question

我正在开发一个发送和接收短信的应用程序。发送是可以的，但是在应用程序运行时接收短信时接收也可以，但是当我关闭应用程序时，我的 BroadcastReceiver 的 onReceive 方法不会执行，实际上我正在开发 android 4，我从一所大学那里听说它可能达到 android 的版本，这意味着 android 4 不会让应用程序在未向用户显示时接收短信。对吗？

这是可以的代码(我认为是这样)

 public class SMSReceiver extends BroadcastReceiver {

private static final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";
private static final String ACTIVITY_SERVICE = "activity";

@Override
public void onReceive(Context context, Intent intent) {
    // something 
   }
  }

这里是 list 相关内容

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

            <action android:name="android.intent.action.PHONE_STATE" />
            <action android:name="android.provider.Telephony.SMS_RECEIVED" />               
        </intent-filter>
    </receiver>

您可以接收短信及其信息。

我已使用以下方式收到它:

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.widget.Toast;

public class SMSReceiver extends BroadcastReceiver
{
    public void onReceive(Context context, Intent intent)
    {

        Bundle myBundle = intent.getExtras();
        SmsMessage [] messages = null;
        String strMessage = "";

        if (myBundle != null)
        {
         //get message in pdus format(protocol discription unit)
            Object [] pdus = (Object[]) myBundle.get("pdus");
            //create an array of messages
            messages = new SmsMessage[pdus.length];

            for (int i = 0; i < messages.length; i++)
            {
             //Create an SmsMessage from a raw PDU. 
                messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                //get the originating address (sender) of this SMS message in String form or null if unavailable 
                strMessage += "SMS From: " + messages[i].getOriginatingAddress();
                strMessage += " : ";
                //get the message body as a String, if it exists and is text based.
                strMessage += messages[i].getMessageBody();
                strMessage += "\n";
            }
            //show message in a Toast
            Toast.makeText(context, strMessage, Toast.LENGTH_SHORT).show();
        }
    }
}
