Android拦截短信并屏蔽Notification

Android拦截短信并屏蔽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

view plaincopy to clipboardprint?

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

 

3.要写个广播接收类

view plaincopy to clipboardprint?

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

view plaincopy to clipboardprint?

<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

view plaincopy to clipboardprint?

<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

view plaincopy to clipboardprint?

// 第三步:取消

        if (flags_filter) {  

            this.abortBroadcast();  

        } 

 

源码如下：

Manifest.xml

view plaincopy to clipboardprint?

<?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：

view plaincopy to clipboardprint?

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 = SmsMessage.createFromPdu((byte[]) _pdus);  

            }  

            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");  

    }  

}
