Android: Test Push Notification Online (Google Cloud Messaging)

Android: Test Push Notification online (Google Cloud Messaging)

Found a very easy way to do this.

Open http://phpfiddle.org/

Paste following php script in box. In php script set API_ACCESS_KEY, set device ids separated by coma.

Press F9 or click Run.

Have fun ;)

<?php

// API access key from Google API's Console
define( 'API_ACCESS_KEY', 'YOUR-API-ACCESS-KEY-GOES-HERE' );

$registrationIds = array("YOUR DEVICE IDS WILL GO HERE" );

// prep the bundle
$msg = array
(
    'message'       => 'here is a message. message',
    '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
);

$fields = array
(
    'registration_ids'  => $registrationIds,
    'data'              => $msg
);

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

$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://android.googleapis.com/gcm/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;
?>

For FCM, google url would be: https://fcm.googleapis.com/fcm/send

For FCM v1 google url would be: https://fcm.googleapis.com/v1/projects/YOUR_GOOGLE_CONSOLE_PROJECT_ID/messages:send

Note: While creating API Access Key on google developer console, you have to use 0.0.0.0/0 as ip address. (For testing purpose).

In case of receiving invalid Registration response from GCM server, please cross check the validity of your device token. You may check the validity of your device token using following url:

https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=YOUR_DEVICE_TOKEN

Some response codes:

Following is the description of some response codes you may receive from server.

{ "message_id": "XXXX" } - success
{ "message_id": "XXXX", "registration_id": "XXXX" } - success, device registration id has been changed mainly due to app re-install
{ "error": "Unavailable" } - Server not available, resend the message
{ "error": "InvalidRegistration" } - Invalid device registration Id 
{ "error": "NotRegistered"} - Application was uninstalled from the device

How to send a push notification from the Firebase console to a specific GCM/FCM device token ID

By design, the notification feature in the console is for sending out broadcast-type events. Sending user-specific alerts would be more of a programmatic operation done through the API.

For sending test messages, there is a console tool for this, explained here.

Note that it is possible to send a notification to one device by subscribing a device to any topic and sending the notification to that topic in the console (keep in mind topics are public and you can't prevent users from signing up to them; fine for testing most likely).

Another alternative is to send a message via HTTP or curl. Perhaps the best resource for this is the quickstart/messaging example.

Firebase cloud messaging notification not received by device

You have placed your service outside the application tag. Change bottom to this.

<service
    android:name=".NotificationGenie">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT"/>
    </intent-filter>
</service>

</application>

test firebase cloud messaging without app

You could you the FCM quick start app available on Github.

https://github.com/firebase/quickstart-android/tree/master/messaging

If you configure the app for your project you can check that your backend is working successfully.

google Cloud Messaging Push notification

Yes, you can.

1. Send a notification with a JSON payload

URL: https://android.googleapis.com/gcm/send

Headers:

• Authorization: key=<your-api-key>
• Content-Type: application/json

Body (click on the 'raw' tab):

{
  "collapse_key": "score_update",
  "time_to_live": 108,
  "delay_while_idle": true,
  "data": {
    "score": "4x8",
    "time": "15:16.2342"
  },
  "registration_ids":["4", "8", "15", "16", "23", "42"]
}

Note: registration_ids is the only required field, all the others are optional.

2. Send a notification with a plain text payload

URL: https://android.googleapis.com/gcm/send

Headers:

• Authorization: key=<your-api-key>
• Content-Type: application/x-www-form-urlencoded;charset=UTF-8

Body (click on the 'x-www-form-urlencoded' tab):

collapse_key=score_update
time_to_live=108
delay_while_idle=1
data.score=4x8
data.time=15:16.2342
registration_id=42

Note: registration_id is the only required field, all the others are optional.
