# Android Setup

To integrate your plugin into the Android part of your app, follow these steps (from the firebase messaging plugin):

1. Using the [Firebase Console](https://console.firebase.google.com/) add an Android app to your project: Follow the assistant, download the generated `google-services.json` file and place it inside `android/app`.
2. Add the classpath to the `[project]/android/build.gradle` file.

```
dependencies {
  // Example existing classpath
  classpath 'com.android.tools.build:gradle:3.5.3'
  // Add the google services classpath
  classpath 'com.google.gms:google-services:4.3.2'
}
```

3\. Add the apply plugin to the `[project]/android/app/build.gradle` file.

```
// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'
```
