通過BroadcastReceiver的短信接收器

Question

我正在發送和接收短信的應用程序。發送是好的，但在接收短信應用程序運行時，接收也可以，但是當我關閉應用程序時，我的BroadcastReceiver的onReceive方法沒有執行，實際上我正在使用android 4，並且我從大學那裏聽說它可能會達到Android的版本，這意味着Android 4不會讓應用程序收到短信時，他們沒有顯示給用戶。這樣對嗎 ？

這裏是正常的代碼（我是這麼認爲的）

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 
    } 
    } 

這裏是明顯的相關內容

<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>

可以接收短信和信息。

我一直在使用接受它：

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(); 
     } 
    } 
}

嘗試使用此代碼：

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 
      } 
     } 
    } 
}

試着改變你的接收器在你的清單以這種

<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> 

安卓出口指示SmsReceiver類必須不僅從應用程序接收事件，而且從整個Android系統接收事件。

android：priority表示您的短信接收的優先級。 1000是默認值，似乎是使用的最佳值。

希望這有助於:)
