FCM is a Firebase Cloud Messaging Android library that demonstrates registering your Android app for notifications and handling the receipt of a message. Example Send Data Message using the HTTP protocol with Postman.

Add firebase to your Android App

After completion of step one, your project should have a google-services.json file added to the root of your project along with the classpath, plugin and dependecies

    classpath 'com.google.gms:google-services:latest-version'

or latest

    id 'com.google.gms.google-services' version 'latest-version' apply false

    id 'com.google.gms.google-services'

no dependencies required

Add maven repository in project level build.gradle or in latest project setting.gradle file

    repositories {
        google()
        mavenCentral()
        maven { url "https://jitpack.io" }
    }

Add FCM dependencies in App level build.gradle.

    dependencies {
             implementation 'com.github.hypersoftdev:fcm:1.0.3'
    }

Finally intialize Firebase and setup FCM in application class or in your "MainActivity"

    SonicFCM.setupFCM(this, "YourTopicName")

If you want to stop receiving notification from the subscribed topic simply call.

    SonicFCM.removeFCM("YourTopicName")

You have to copy Legacy Server Key from Firebase Console > Project Settings > Cloud Messaging

Firebase has upgraded our server keys to a new version. You may continue to use your Legacy server key, but it is recommended that you upgrade to the newest version. If anyone else is facing any issue then First Enabled "Firebase Cloud Messaging API" from Firebase console.

• Open Postman, click on Enter request URL textbox, enter firebase url

 https://fcm.googleapis.com/fcm/send

• Then change request type to "POST"
• Now to click on Header and add two params "Content-Type" and "Authorization"

 Content-Type: application/json
 Authorization: key=AAAAp5XtBPY:APA91bG_fypMd0j... //FCM SERVER KEY

• Now click on "Body" than select "Raw" and add value as JSON object like below

{
      "to":"/topics/YourTopicName", 
      "data":
      {
                "title": "My Application Titile is Here",
	        "short_desc": "My Application Short Description is here",
	        "icon": "App Icon link is here",
	        "feature": "App Feature Image Link is here",
	        "package": "Promotional app package name is here"
      }
  }

These Three items are mandatory for notification

• title
• icon
• short_desc

These Three items are optional for notification

• long_desc
• feature
• package (in case of other app promotion)
