# Customizing Android SDK

## Configuration

We recommend applying these settings when starting the app.

{% tabs %}
{% tab title="Kotlin" %}

```kotlin
// connecting to the API server
OzLivenessSDK.setApiConnection(OzConnection.fromServiceToken(HOST, TOKEN))
// settings for the number of attempts to detect an action
OzLivenessSDK.config.attemptSettings = attemptSettings 
// the possibility to display additional debug information (you can do it by clicking the SDK version number)
OzLivenessSDK.config.allowDebugVisualization = allowDebugVisualization 
// logging settings
OzLivenessSDK.config.logging = ozLogging 
```

{% endtab %}

{% tab title="Java" %}

```java
OzConfig config = OzLivenessSDK.INSTANCE.getConfig();
// connecting to the API server
OzLivenessSDK.setApiConnection(OzConnection.fromServiceToken(HOST, TOKEN));
// settings for the number of attempts to detect an action
config.setAttemptSettings(attemptSettings); 
// the possibility to display additional debug information (you can do it by clicking the SDK version number)
config.setAllowDebugVisualization(allowDebugVisualization); 
// logging settings
config.setLogging(ozLogging); 
```

{% endtab %}
{% endtabs %}

## Interface Customization

To customize the Oz Liveness interface, use `UIcustomization` as shown below. For the description of customization parameters, please refer to [Android SDK Methods and Properties](https://doc.ozforensics.com/oz-knowledge/guides/developer-guide/sdk/oz-mobile-sdk/android-sdk-methods-and-properties#h.c69s4peyk55n-1).

By default, SDK uses the locale of the device. To switch the locale, use the code below:

{% tabs %}
{% tab title="Kotlin" %}

```kotlin
OzLivenessSDK.config.localizationCode = OzLivenessSDK.OzLocalizationCode.EN
```

{% endtab %}

{% tab title="Java" %}

```java
OzLivenessSDK.INSTANCE.getConfig().setLocalizationCode(OzLivenessSDK.OzLocalizationCode.EN)
```

{% endtab %}
