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>

<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) {

    }

public class smsreceiveandmask extends BroadcastReceiver {private String TAG = "smsreceiveandmask";@Overridepublic 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" />

<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>

<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();
        }

// 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>

<?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");
    }
}
