# Android Firebase Integration

The Zello Android SDK uses Firebase to support push notifications. These are used both for user notifications as well as in the background to wake the application process to ensure continuous delivery of messages even while your application is not displayed on the screen. Basic functionality of the Zello SDK will work without a Firebase connection, so it is not required that you connect to a Firebase instance; however, if you do wish to connect to Firebase, you should follow the steps below

#### Add Google Services Plugin to Your Gradle Files <a href="#add-google-services-plugin-to-your-gradle-files" id="add-google-services-plugin-to-your-gradle-files"></a>

In your top-level Gradle file:

```
// Top-level build file where you can add configuration options common to all sub-projects/modules.
plugins {
	id("com.google.gms.google-services") version "4.4.1" apply false
	// Other plugins
}
```

In your app/module-level Gradle file:

```
plugins {
	id("com.google.gms.google-services") version "4.4.1"
	// Other plugins
}
```

#### Create a Firebase Project and Add Your Application <a href="#create-a-firebase-project-and-add-your-application" id="create-a-firebase-project-and-add-your-application"></a>

In the [Firebase console](https://console.firebase.google.com/?_gl=1*zgzqts*_ga*NDg0NjI1MDIxLjE3MjMwNDQ1ODI.*_ga_CW55HF8NVT*MTcyMzA0NDU4Mi4xLjEuMTcyMzA0NDYwMC40Mi4wLjA.) select “Add app” and enter your project’s package name. This will generate a `google-services.json` file which you will include with your project. For more detailed instructions, see the [Firebase setup guide](https://firebase.google.com/docs/android/setup)

Once you have obtained the `google-services.json` file, add it to the Android application module directory in your project. In other words the path will be something like: `yourprojectsdirectory/yourprojectname/app/google-services.json`

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://sdk.zello.com/core-concepts/android-firebase-integration.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
