PHP Question

Firebase Cloud Messaging, issues in receiving notification

I'm trying to write an application to receive notifications via Firebase Cloud Messaging. It initially worked when I tried to send the message via Firebase console but then the moment I tried doing the same using php webservice, in response, it showed success but I neither received the message nor am I able to get any more notifications via firebase console. Please help

My server side code:

MainActivity.java

package com.example.mojojojo.firebasenotifications;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.content.SharedPreferences;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.EditText;

import com.google.firebase.iid.FirebaseInstanceId;

public class MainActivity extends AppCompatActivity {

private EditText etToken;
private SharedPreferences sp;
private SharedPreferences.Editor edit;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
etToken=(EditText)findViewById(R.id.etToken);

sp=getSharedPreferences("pref",MODE_PRIVATE);
edit=sp.edit();

etToken.setText(FirebaseInstanceId.getInstance().getToken());
BroadcastReceiver tokenReceiver=new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String token=intent.getExtras().getString("token");
if(token!=null){
etToken.setText(token);
}
}
};
registerReceiver(tokenReceiver,new IntentFilter("TOKEN_GENERATED"));
}
}


Messaging service

package com.example.mojojojo.firebasenotifications;

import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.media.RingtoneManager;
import android.net.Uri;
import android.os.IBinder;
import android.support.v4.app.NotificationCompat;
import android.util.Log;

import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;

public class MessagingService extends FirebaseMessagingService {

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
String msg=remoteMessage.getNotification().getBody();
sendNotification(msg);
Log.i("/>/>",msg);
}
private void sendNotification(String messageBody) {
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 , intent,
PendingIntent.FLAG_ONE_SHOT);

Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle("FCM Message")
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);

NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

notificationManager.notify(0 , notificationBuilder.build());
}
}


Token Service

package com.example.mojojojo.firebasenotifications;

import android.app.Service;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.IBinder;

import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;

public class TokenService extends FirebaseInstanceIdService {
private SharedPreferences sp;
private SharedPreferences.Editor edit;

@Override
public void onTokenRefresh() {
super.onTokenRefresh();

sp=getSharedPreferences("pref",MODE_PRIVATE);
edit=sp.edit();

String token= FirebaseInstanceId.getInstance().getToken();
edit.putString("token",token);

Intent tokenIntent=new Intent("TOKEN_GENERATED");
tokenIntent.putExtra("token",token);
sendBroadcast(tokenIntent);
}
}


Manifest

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.mojojojo.firebasenotifications">

<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />

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

<service
android:name=".MessagingService"
android:enabled="false"
android:exported="false" >
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>

<service
android:name=".TokenService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
</application>

</manifest>


and my php code is as follows (I've removed the server Key in the code)

<?php
define( 'API_ACCESS_KEY', 'YOUR-API-ACCESS-KEY-GOES-HERE' );
$registrationIds = array( $_GET['id'] );
// prep the bundle
$msg = array
(
'message' => 'hi',
'title' => 'This is a title. title',
'subtitle' => 'This is a subtitle. subtitle',
'tickerText' => 'Ticker text here...Ticker text here...Ticker text here',
'vibrate' => 1,
'sound' => 1,
'largeIcon' => 'large_icon',
'smallIcon' => 'small_icon'
);
$fields = array
(
'registration_ids' => $registrationIds,
'data' => $msg
);

$headers = array
(
'Authorization: key=' . 'xxxxxxxxxxxxxxxxxxxxx',
'Content-Type: application/json'
);

$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send' );
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) );
$result = curl_exec($ch );
curl_close( $ch );
echo $result;
?>

Answer

This php code finally worked for me.

<?php 
function send_notification ($tokens)
{

    $url = 'https://fcm.googleapis.com/fcm/send';
    $priority="high";
    $notification= array('title' => 'Some title','body' => 'hi' );

    $fields = array(
         'registration_ids' => $tokens,
         'notification' => $notification

        );


    $headers = array(
        'Authorization:key=xxxxxxxxxxxxx',
        'Content-Type: application/json'
        );

   $ch = curl_init();
   curl_setopt($ch, CURLOPT_URL, $url);
   curl_setopt($ch, CURLOPT_POST, true);
   curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
   curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);  
   curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
   curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
    // echo json_encode($fields);
   $result = curl_exec($ch);           
   echo curl_error($ch);
   if ($result === FALSE) {
       die('Curl failed: ' . curl_error($ch));
   }
   curl_close($ch);
   return $result;
}
$tokens = array('RECEIVER-TOKEN-1'
    ,'RECEIVER_TOKEN-2');

  $message_status = send_notification($tokens);
  echo $message_status;
?>

P.S: I've hard coded the receiver tokens as of now (for testing purposes)
