Android拦截短信并屏蔽系统的Notification

jopen 10年前

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

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

3.要写个广播接收类

public class smsreceiveandmask extends BroadcastReceiver {   private String TAG = "smsreceiveandmask";   @Override   public void onReceive(Context context, Intent intent) {       }
 

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

<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:

 

package com.hwttnet.test.smsreceiveandmask;  import android.app.Activity;  import android.content.BroadcastReceiver;  import android.content.Context;  import android.content.Intent;  import android.os.Bundle;  import android.telephony.SmsMessage;  import android.util.Log;  public class smsreceiveandmask extends BroadcastReceiver {   private String TAG = "smsreceiveandmask";   @Override   public void onReceive(Context context, Intent intent) {    Log.v(TAG, ">>>>>>>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.getDisplayOriginatingAddress());     }     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");   }  }
