Android APP: BlackContact 短信拦截

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" >

        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!!
