android拦截短信并屏蔽系统的Notif…

拦截短信有几个关键点：

1.android接收短信时是以广播的方式

2.程序只要在自己的Manifest.xml里加有"接收"SMS的权限

" quality="high" allowscriptaccess="always" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer">
   
 
  
<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>

3.要写个广播接收类

publicclasssmsreceiveandmask extendsBroadcastReceiver {  
   privateString TAG = "smsreceiveandmask";  
   @Override 
   publicvoidonReceive(Context context, Intent intent) {  
         
   }

4.Manifest.xml的receiver标签里要加入intent-filter ,action为

" quality="high" allowscriptaccess="always" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer">
   
 
  
<action android:name="android.provider.Telephony.SMS_RECEIVED"/>

5.重要的是要在这个intent-filter上加上priority优先级，以使自己接收到SMS优先于系统或其它软件

<receiver android:name=".smsreceiveandmask">  
           <intent-filter android:priority="1000">   
               <action android:name="android.provider.Telephony.SMS_RECEIVED"/>  
           </intent-filter>  
       </receiver>

6.当自己的程序接收到要屏蔽的SMS后，用 this.abortBroadcast();来结束广播的继续发给别的程序，这样系统就不会收到短信广播了，Notification也不会有提示了

// 第三步:取消 
       if(flags_filter) {  
           this.abortBroadcast();  
       }

源码如下：

Manifest.xml

<?xml version="1.0"encoding="utf-8"?>  
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
   package="com.hwttnet.test.smsreceiveandmask"android:versionCode="1" 
   android:versionName="1.0">  
   <uses-sdk android:minSdkVersion="3"/>  
   <uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>  
   <application android:icon="@drawable/icon"android:label="@string/app_name">  
       <receiver android:name=".smsreceiveandmask">  
           <intent-filter android:priority="1000">   
               <action android:name="android.provider.Telephony.SMS_RECEIVED"/>  
           </intent-filter>  
       </receiver>  
   </application>  
</manifest>

BroadcastReceiver类：

>>>>>>onReceive start"); // 第一步、获取短信的内容和发件人 StringBuilder body = new StringBuilder();// 短信内容 StringBuilder number = new StringBuilder();// 短信发件人 Bundle bundle = intent.getExtras(); if (bundle != null) { Object[] _pdus = (Object[]) bundle.get("pdus"); SmsMessage[] message = new SmsMessage[_pdus.length]; for (int i = 0; i < _pdus.length; i++) { message[i] = SmsMessage.createFromPdu((byte[]) _pdus[i]); } for (SmsMessage currentMessage : message) { body.append(currentMessage.getDisplayMessageBody()); number.append(currentMessage.getDisplayOriginatingAdd
    ress()); } String smsBody = body.toString(); String smsNumber = number.toString(); if (smsNumber.contains("+86")) { smsNumber = smsNumber.substring(3); } // 第二步:确认该短信内容是否满足过滤条件 boolean flags_filter = false; if (smsNumber.equals("10086")) {// 屏蔽10086发来的短信 flags_filter = true; Log.v(TAG, "sms_number.equals(10086)"); } // 第三步:取消 if (flags_filter) { this.abortBroadcast(); } } Log.v(TAG, ">>>>>>>onReceive end"); } }" quality="high" allowscriptaccess="always" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer">
