Prerequisites 

To develop Firebase applications, you can surely use your development environment; the essential requirements are as follows:

1. Your favorite operating system (Windows, macOS, or Linux)
2. Determine whether you have the latest JRE installed on your operating system
3. Install the latest version of JDK or Open JDK
4. Install the newest version of Android Studio (at the time of writing, the most recent stable version is 2.3.3 and 3.0 is still in beta, or any newer version should also be excellent)
5.  Android SDK with one complete API will be very significant

Before we continue to create our first Firebase Realtime Database Android application, ensure that you have one complete version of Android API installed, and you have the latest version of Android Studio.
