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" >

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

<application

android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@android:style/Theme.Black.NoTitleBar" >

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!!
