# 3. Set Android SDK Version Compatibility

In the `build.gradle` file, ensure the Android SDK version compatibility. WinZO requires:

* Works best with a `compileSdkVersion` of 31
* `minSdkVersion` of 23 or higher
* `targetSdkVersion` of 31

If you want to learn more about what's the difference between compiledSdkVersion and targetSdkVersion, you can check out the official [Android developer documentation](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html).

{% code title="build.gradle" %}

```gradle
android {
    compileSdkVersion 31

    defaultConfig {
        minSdkVersion 23
        targetSdkVersion 31        
    }
}
```

{% endcode %}
