Android APP: BlackContact 短信拦截

来源：互联网发布：中拓互联中文域名编辑：程序博客网时间：2024/05/01 13:35

由于 4.2版本后已经取消了 abortBroadcast() 的功能，所以在实现这功能的时候需要先将原有 Message APP 中的 notification 功能 disable, 方法如下截图:

接着编写用来接受 Message 的 broadcast 类 SmsReceiver.java

package com.elvis.android.blackcontacts;import android.app.admin.DevicePolicyManager;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.content.SharedPreferences;import android.util.Log;import android.os.Bundle;import android.telephony.SmsMessage;import android.widget.Toast;/** * Created by elvis on 10/22/15. */public class SmsReceiver extends BroadcastReceiver {    private final String TAG = "SmsReceiver";    private BlackInfoDBHelper dbhelper;    private SharedPreferences sp;    private DevicePolicyManager devicePolicyManager;    @Override    public void onReceive(Context context, Intent intent) {        Log.i(TAG, "Message Received!!!");        dbhelper = new BlackInfoDBHelper(context);        final Bundle bundle = intent.getExtras();        try {            devicePolicyManager = (DevicePolicyManager)                        context.getSystemService(Context.DEVICE_POLICY_SERVICE);            Object[] pdus = (Object[]) intent.getExtras().get("pdus");            for(Object pdu:pdus) {                SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdu);                String phoneNumber = currentMessage.getDisplayOriginatingAddress();                String message = currentMessage.getDisplayMessageBody();                Log.i(TAG, phoneNumber + ":" + message);                if (dbhelper.isBlackNumber(phoneNumber)) {                    Log.i(TAG, "Block!!!");                    //abortBroadcast();                } else {                    for (int i = 0; i < 1000; i++)                        Toast.makeText(context, phoneNumber + ":" + message,                                Toast.LENGTH_LONG).show();                }            }        } catch (Exception e) {            Log.e(TAG, "Exception smsReceiver" +e);        }    }}

并在AndroidManifest.xml 宣告权限

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.elvis.android.blackcontacts" >    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>    <uses-permission android:name="android.permission.RECEIVE_SMS"/>    <uses-permission android:name="android.permission.READ_SMS"/>    <uses-permission android:name="android.permission.SEND_SMS"/>    <uses-permission android:name="android.permission.RAISED_THREAD_PRIORITY"/>    <uses-permission android:name="android.permission.CALL_PHONE"/>    <application        android:allowBackup="true"        android:icon="@mipmap/ic_launcher"        android:label="@string/app_name"        android:theme="@android:style/Theme.Black.NoTitleBar" >        <activity            android:name=".MainActivity"            android:label="@string/app_name" >            <intent-filter android:priority="1000">                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>        <receiver android:name="com.elvis.android.blackcontacts.CallReceiver">            <intent-filter android:priority="1000">                <action android:name="android.intent.action.PHONE_STATE"/>            </intent-filter>        </receiver>        <receiver android:name="com.elvis.android.blackcontacts.SmsReceiver"            android:permission="android.permission.BROADCAST_SMS">            <intent-filter android:priority="1">                <action android:name="android.provider.Telephony.SMS_RECEIVED"/>            </intent-filter>        </receiver>    </application></manifest>

以下为测试展示:

当用黑名单号码发短信时，没有反应

当用另外一个号码发短信时, 会提示发送的号码及内容

Done!!
