# Firebase

> Set up Firebase in your project with the Choicely Android SDK

Follow these steps to set up Firebase in your project with the Choicely Android SDK.

Firebase is required to enable certain features in the Choicely Android SDK.

## Why Firebase?

* **Push Notifications** – Firebase Cloud Messaging (FCM) allows the app to send push notifications directly to users, helping you keep them engaged with instant updates, news, or alerts.
* **Realtime Updates** – With Firebase Realtime Database, content and configuration changes can be delivered instantly to your users without requiring an app update. This ensures your app always reflects the latest data.
* **Social Login** – The Choicely SDK integrates with Firebase Authentication to enable sign-in with popular providers such as Google, Facebook, and Apple. This makes it easy for users to log in without creating a separate account.

## Gradle Setup

Add the Firebase dependency and plugin configuration in your `build.gradle` files.

### 1. Add Dependency

```gradle theme={null}
implementation(platform("com.choicely.sdk:bom:1.1.0"))
implementation("com.choicely.sdk:android-core")
implementation("com.choicely.sdk:android-firebase")
```

### 2. Add Plugin in App-level build.gradle

```gradle theme={null}
plugins {
    id("com.google.gms.google-services")
}
```

### 3. Add Plugin in Project-level build.gradle

```gradle theme={null}
plugins {
    ...
    id("com.google.gms.google-services") version "4.4.3" apply false
}
```
