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");
	}
}

smsreceiveandmask 类名小写开头的？

这个程序没有 activity 怎么运行呀? 新手，请指教。能发源码吗?
