Question

我正在开发一个发送和接收短信的应用。发送是可以的，但是在应用程序运行时收到短信接收也可以，但是当我关闭应用程序时，我的BroadcastReceiver的onReceive方法没有执行，实际上我正在研究android 4而且我从大学那里听到了它可能是Android的版本，这意味着Android 4不允许应用程序接收短信时，他们没有向用户显示。是不是？

这里的代码是好的（我想是的）

 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 
   }
  }

这里是与清单相关的内容

<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.SEND_SMS" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="15" />

  <receiver
        android:name="com.ssol.SMSReceiver"
        android:permission="android.permission.BROADCAST_SMS" >
        <intent-filter android:priority="2147483647" >
            <action android:name="android.intent.action.PHONE_STATE" />
            <action android:name="android.provider.Telephony.SMS_RECEIVED" />               
        </intent-filter>
    </receiver>

你可以收到短信及其信息。

我使用以下方式收到：

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();
        }
    }
}

尝试将清单中的接收器更改为

 <receiver
        android:name="com.ssol.SMSReceiver android:exported="true""
        android:permission="android.permission.BROADCAST_SMS" >
        <intent-filter android:priority="1000" >
            <action android:name="android.intent.action.PHONE_STATE" />
            <action android:name="android.provider.Telephony.SMS_RECEIVED" />               
        </intent-filter>
    </receiver>

android：exported表示SmsReceiver类不仅必须从应用程序接收事件，还要从整个Android系统接收事件。

android：priority表示短信接收的优先级。 1000是默认值，似乎是最佳使用值。

希望这有帮助:)

尝试使用此代码：

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

public class ReadSMS extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle myBundle = intent.getExtras();
        SmsMessage[] messages = null;

        if (myBundle != null) {
            Object[] pdus = (Object[]) myBundle.get("pdus");
            messages = new SmsMessage[pdus.length];
            String SMS = "";

            for (int i = 0; i < messages.length; i++) {
                messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                SMS = messages[i].getMessageBody();4
                //SMS is the text content
            }
        }
    }
}
