How to detect when mobile phone received the SMS Message on Android.

Published by Igor Khrupin on

To receive SMS messages you need to create BroadcastReceiver for it.

Below you can download source code of sample Android project

Here is SmsBroadcastReceiver.java

package com.hrupin.sample.sms;

import android.content.BroadcastReceiver;
import android.content.ContentValues;
import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;
import android.widget.Toast;

public class SmsBroadcastReceiver extends BroadcastReceiver {

    private static final String TAG = SmsBroadcastReceiver.class.getSimpleName();
    public static final String SMS_CONTENT = "sms_content";

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.i(TAG, "Intent recieved: " + intent.getAction());

        Cursor c = context.getContentResolver().query(Uri.parse("content://sms/inbox"), null, null, null, null);
        c.moveToFirst();
        String smsBody = c.getString(12);
        Toast.makeText(context, "SMS RECEIVED:", Toast.LENGTH_LONG).show();
        Toast.makeText(context, smsBody, Toast.LENGTH_LONG).show();

        Intent fireActivityIntent = new Intent(context, SMSDetectorActivity.class);
        fireActivityIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        fireActivityIntent.putExtra(SMS_CONTENT, smsBody);
        context.startActivity(fireActivityIntent);

    }
}

Also you need specific permissions:

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

Next step is put BroadcastReceiver into AndroidManifest

<application android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name">
    ..................
    <receiver android:name=".SmsBroadcastReceiver">
        <intent-filter>
            <action android:name="android.provider.Telephony.SMS_RECEIVED">
            </action>
        </intent-filter>
    </receiver>
</application>
