# Setup

Follow these steps to integrate and configure the Auto Update SDK in your Unity project.

## Step 1 | Import the SDK

Import the Unity Auto Update SDK package file into your project.

## Step 2 | Modify the Unity manifest file

First, make sure the **AndroidManifest**, **mainTemplate**, and **gradleTemplate** files can be updated. To do this, go to **Edit > Project Settings > Publishing Settings** and enable the following options:

* **Custom Main Manifest**: Makes the manifest file editable so you can add additional configurations.
* **Custom Main Gradle Template**: Makes the Gradle template editable for adding custom properties.
* **Custom Gradle Properties Template**: Allows you to manually build options and dependencies.

Once enabled, update your **AndroidManifest** file to include the necessary permissions, activity, and content provider:

1. Include these permissions:

```xml theme={"system"}
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />
```

2. Add an activity to request installation permissions from the players:

```xml theme={"system"}
<activity
    android:name="com.appcharge.update.InstallPermissionHelperActivity"
    android:theme="@android:style/Theme.Translucent.NoTitleBar"
    android:exported="false" />
```

3. Add the following provider tag in the `<application>` tag:

```xml theme={"system"}
<provider
	android:name="androidx.core.content.FileProvider"
	android:authorities="${applicationId}.fileProvider"
	android:exported="false"
	android:grantUriPermissions="true">
  <meta-data
		android:name="android.support.FILE_PROVIDER_PATHS"
		android:resource="@xml/paths" />
</provider>
```
