android拦截短信并屏蔽系统的Notification

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"); } }
