Application to Application Notifications

I am creating a Taxi App in which I have a driver application and a user application. When a user posts a request for a ride, ALL drivers must be notified that a request is available (Push Notifications). How can my native code know when to send notification?m

I don't want the Application to be Battery and Data Hungry, so I can't run a check over my MySQL database every minute. I looked for a solution with Firebase, but found out that they provide service for web to android notifications. I haven't written any code related to that yet.

Please suggest a way to achieve this. Googling it didn't help. If possible, attach code.

Thanks in Advance

So firebase is not that difficult to use, here is the code for your PHP Api

// function makes curl request to firebase servers
private function sendPushNotification($fields) {

    require_once __DIR__ . '/config.php';

    // Set POST variables
    $url = 'https://fcm.googleapis.com/fcm/send';

    $headers = array(
        'Authorization: key=' . FIREBASE_API_KEY,
        'Content-Type: application/json'
    );
    // Open connection
    $ch = curl_init();

    // Set the url, number of POST vars, POST data
    curl_setopt($ch, CURLOPT_URL, $url);

    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    // Disabling SSL Certificate support temporarly
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));

    // Execute post
    $result = curl_exec($ch);
    if ($result === FALSE) {
        die('Curl failed: ' . curl_error($ch));
    }

    // Close connection
    curl_close($ch);

    return $result;
}

And now what config.php has is

<?php

// Firebase API Key
define('FIREBASE_API_KEY', '///lGrYwgBC8iz5reyx4qPUB7ByXX8MwC7Vcs8u...');
     ?>

You can get this key from Firebase Console under Project Settings -> Cloud Messaging -> Server Key

and now one simple function to send push notification

public function send($to, $message) {
    $fields = array(
        'to' => $to,
        'data' => $message,
    );
    return $this->sendPushNotification($fields);
}

Here in $to will come the Notification Id of the person you want to send notification. Here is the link.

Hope this helps you
