Android programming to block SMS and block Notification system method

This paper illustrates the Android programming method to block SMS and block Notification. To share for your reference, the details are as follows:

There are a few key points about SMS interception:

1.android receives SMS messages via radio

2. The program only needs to add "receive "SMS to its own ES10en.xml

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

3. Write a broadcast receiver class

public class smsreceiveandmask extends BroadcastReceiver {
  private String TAG = "smsreceiveandmask";
  @Override
  public void onReceive(Context context, Intent intent) {
}
public class smsreceiveandmask extends BroadcastReceiver {
  private String TAG = "smsreceiveandmask";
  @Overridepublic void onReceive(Context context, Intent intent) {} 

4. Add ES22en-ES23en and action to the receiver tag of Manifest

<action android:name="android.provider.Telephony.SMS_RECEIVED" />
<action android:name="android.provider.Telephony.SMS_RECEIVED" />

5. It is important to put the priority priority on the ES28en-ES29en so that you receive SMS over the system or other software

<receiver android:name=".smsreceiveandmask" > 
      <intent-filter android:priority="1000">  
        <action android:name="android.provider.Telephony.SMS_RECEIVED" /> 
      </intent-filter> 
    </receiver> 
<receiver android:name=".smsreceiveandmask" >
<intent-filter android:priority="1000">
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>

6. When your own program receives SMS to be blocked, use this. abortBroadcast(); To end the broadcast and send it to another program, so that the system will not receive the SMS broadcast, and Notification will not be prompted

//  The first 3 step : cancel  
if (flags_filter) {
  this.abortBroadcast();
}
//  The first 3 step : cancel if (flags_filter) {this.abortBroadcast();}

Source code is as follows:

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>

<?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-permission android:name="android.permission.RECEIVE_SMS">

<intent-filter android:priority="1000">
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
</application>
</manifest>

BroadcastReceiver class:

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");
    //  The first 1 Step, get the content of the message and the sender 
    StringBuilder body = new StringBuilder();//  Message content 
    StringBuilder number = new StringBuilder();//  SMS sender 
    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);
      }
      //  The first 2 step : Verify that the message content meets the filtering criteria 
      boolean flags_filter = false;
      if (smsNumber.equals("10086")) {//  shielding 10086 Text message from 
        flags_filter = true;
        Log.v(TAG, "sms_number.equals(10086)");
      }
      //  The first 3 step : cancel 
      if (flags_filter) {
        this.abortBroadcast();
      }
    }
    Log.v(TAG, ">>>>>>>onReceive end");
  }
}
