--------------------------And then you go this link-----------------------

     https://console.firebase.google.com/  

Enter your application name and select your country. then click on create project

  Now you will see a screen like this

1. then click on "add Firebase to your Android app" 
2.  
3. .Now put 
1. Package name  
2. App nickname (optional)
3. Debug signing certificate SHA-1 (optional)  

  Copy and paste the google-services.jFirebase Cloud Messaging(FCM)son file into the application root directory.

 and go to project and paste them into app folder

Splash Screen

Android is the mobile operating system developed by Google. Essentially, Google produces the software that runs almost every other mobile phone besides Apple’s iPhone. There are also some popular Android tablets as well. Android is a Linux-based software system, and similar to Linux, is free and open source software. This means that other companies can use the Android operating system developed by Google and use it in their mobile devices (more on that later). The distinguishing factor of this brand is a kernel. Android hosts a central core, which essentially is a strip code that helps the software operate.
Android development is the great mobile developing language this time for those person who will be  interested for software development.
