SMS READER IN ANDROID


SMS READER IN ANDROID:

Now a days many application providing functionality for SMS. In android programming we can implement this functionality with the below permission permissions

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

Below example code can be copied from here in desired application and It can read all inbox as well as it updates SMS when new SMS comes on user device.

We can develop whole messaging apps if we want make that functionality to part of our application like few apps providing that functionality to make their apps as a default messenger app.
Here is SMS reader example

Android manifest permission:

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

<activity
    android:name=".SmsActivity"
    android:label="@string/app_name" >
   <!-- <intent-filter>
        <action android:name="android.intent.action.MAIN" />

        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>-->
</activity>

<receiver android:name=".SmsBroadcastReceiver" android:exported="true" >
    <intent-filter android:priority="999" >
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

}


Broadcast receiver – SmsBroadcastReceiver :

package com.example.com.testapp;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.widget.Toast;

public class SmsBroadcastReceiver extends BroadcastReceiver {

    public static final String SMS_BUNDLE = "pdus";

    public void onReceive(Context context, Intent intent) {
        Bundle intentExtras = intent.getExtras();
        if (intentExtras != null) {
            Object[] sms = (Object[]) intentExtras.get(SMS_BUNDLE);
            String smsMessageStr = "";
            for (int i = 0; i < sms.length; ++i) {
                SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) sms[i]);

                String smsBody = smsMessage.getMessageBody().toString();
                String address = smsMessage.getOriginatingAddress();

                smsMessageStr += "SMS From: " + address + "\n";
                smsMessageStr += smsBody + "\n";
            }
            Toast.makeText(context, smsMessageStr, Toast.LENGTH_SHORT).show();

            //this will update the UI with message
            SmsActivity inst = SmsActivity.instance();
            inst.updateList(smsMessageStr);
        }
    }
}


I have write here only for reader code making few changes sms writing functionality can be implemented.
