android攔截短信並屏蔽系統的Notification,gsm短信攔截系統
攔截短信有幾個關鍵點:
1.android接收短信時是以廣播的方式
2.程序只要在自己的Manifest.xml裡加有"接收"SMS的權限
- <uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
3.要寫個廣播接收類
- public class smsreceiveandmask extends BroadcastReceiver {
- private String TAG = "smsreceiveandmask";
- @Override
- public void onReceive(Context context, Intent intent) {
-
- }
4.Manifest.xml的receiver標簽裡要加入intent-filter ,action為
- <action android:name="android.provider.Telephony.SMS_RECEIVED" />
5.重要的是要在這個intent-filter上加上priority優先級,以使自己接收到SMS優先於系統或其它軟件
- <receiver android:name=".smsreceiveandmask" >
- <intent-filter android:priority="1000">
- <action android:name="android.provider.Telephony.SMS_RECEIVED" />
- </intent-filter>
- </receiver>
6.當自己的程序接收到要屏蔽的SMS後,用 this.abortBroadcast();來結束廣播的繼續發給別的程序,這樣系統就不會收到短信廣播了,Notification也不會有提示了
- // 第三步:取消
- if (flags_filter) {
- this.abortBroadcast();
- }
源碼如下:
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類:
- 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、獲取短信的內容和發件人
- StringBuilder body = new StringBuilder();// 短信內容
- StringBuilder number = new StringBuilder();// 短信發件人
- 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:確認該短信內容是否滿足過濾條件
- boolean flags_filter = false;
- if (smsNumber.equals("10086")) {// 屏蔽10086發來的短信
- 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");
- }
- }
