# GDK Installation Guide

## Requirements

* Unity 2022.3.39+
* Minimum Android SDK version: 24
* Minimum iOS version: 12.0

## Import GDK package

* Download the latest GDK Unity package \[here]
* Import `.unitypackage` into your project

## Setup

Drag and drop the GDK prefab from `Assets/NEGdk/Prefab/NEGdk.prefab` into your start scene

Select the NEGdk GameObject and update the configuration in the Inspector for your game.

NEGDK uses Ramper to support social login on Android and iOS. Your app's `scheme` must be configured for this feature to work. Follow the section below for setting up your app's `scheme` on Android and iOS.

### Setup for Android

* Create custom `AndroidManifest` by checking the box `Custom Main Manifest` in `Player Setting/Android/Publising Settings`. `AndroidManifest` 
* The file will be found at `Assets/Plugins/Android/AndroidManifest.xml`
* Add your app's scheme in `activity` section in `AndroidManifest.xml`:

{% code fullWidth="true" %}

```xml
<application>
        <activity android:name="com.unity3d.player.UnityPlayerActivity"
                  android:theme="@style/UnityThemeSelector">

            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data android:scheme="your_app_scheme"/>
            </intent-filter>
    
        </activity>
    </application>
```

{% endcode %}

* Add INTERNET permission in `AndroidManifest.xml`:

{% code fullWidth="true" %}

```xml
<uses-permission android:name="android.permission.INTERNET" />
```

{% endcode %}

### Setup for iOS

* Update `Assets/NEGdk/Editor/IOSPostProcessBuild.cs` to add your app scheme for iOS automatically whenever building an XCode project with Unity:

{% code fullWidth="true" %}

```csharp
public static class IOSPostProcessBuild
{
    // UPDATE YOUR APP SCHEME HERE
    private static readonly string BundleURLScheme = "your_app_scheme"; 
```

{% endcode %}
