## Prerequisites
1. The Latest Version of Android Studio
2. Device running Android 4.0 or newer

### Connect firebase using one of this two ways:
1. Connect using Firebase Assistant in Android Studio
2. Connect firebase [using the GUI](https://developer.android.com/studio/write/firebase).
3. Connect firebase manually 
 
The easiest way to connect to firebase is to use the firebase assistant. 

#### Connecting using Firebase Assistant in Android Studio
1. Create an account in the [Firebase Console](https://console.firebase.google.com). 
   - Click add project to add your Android Studio project to it. 

2. Install Google Repository
   - You can do this by adding the dependency into your project-level build.gradle file like this:

```java
allprojects {
  repositories {
    maven {
      url "https://maven.google.com" // Google's Maven repository
    }
  }
}
```

#### Connect firebase [using the GUI](https://developer.android.com/studio/write/firebase). 

1. Go to Tools > Firebase and select Connect to Firebase

#### Connect to firebase [manually](https://firebase.google.com/docs/android/setup))

Having connected your Android Studio project to Firebase, you can either 
1. Click on a product in the firebase assistant and get taken to the Google docs where you will be told how to proceed
2. Go to desired product in **Project Overview** in the Console and click on **Get Started** 
3. Go to the [Firebase docs](https://www.firebase.com/docs/android/quickstart.html) to see how to setup individual products in your project

Reading a combination of all three will enable you to setup the product, which includes adding suitable dependencies to your build.gradle file.

**If You Encounter Gradle Sync errors**
Try To Change The Firebase-core Version or Firebase-database version
