# Installation

## Installation

Here is how to install the Wepin Unity SDK.

### Download it from Github.

The Wepin Unity SDK is distributed on the [wepin-unity-sdk Github](https://github.com/WepinWallet/wepin-unity-sdk). Download the <mark style="color:blue;">`wepinSDK_vX.X.X.unitypackage`</mark> file and import the package file into your Unity3D project.

If you encounter the following error when importing this package,

```
The type or namespace name 'Newtonsoft' could not be found (are you missing a using directive or an assembly reference?)
```

Please add dependency "com.unity.nuget.newtonsoft-json": "3.0.2" Packages/manifest.json file in the project root.

## For iOS

### Modify Info file

In Xcode, you need to register URL Schemes in the Info file.

The value of URL Schemes should be your <mark style="color:blue;">`App Bundle ID + .wepin`</mark>.

## For Android

### Modify AndroidManifest

To use Wepin in your app, you need to modify the AndroidManifest.xml file of your app.

#### Add Permissions

Add the following permission to the main Activity of your app to use Wepin.

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

#### Add Intent Filter for Wepin Activity

You need to add an intent filter for the Wepin activity in your app's AndroidManifest.xml. The schema value you add should be <mark style="color:blue;">`your app's package name + .wepin`</mark>.

```xml
  <activity android:name="com.unity3d.player.UnityPlayerActivity"
    ....
  >
      <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="PACKAGE_NAME.wepin"/> <!-- package name of your android app + '.wepin' -->
      </intent-filter>            
    ....
  </activity>
```
