# OnInitCallback

This interface is used with [`init(SdkConfig, OnInitCallback)`](https://github.com/sentiance/v4-docs/blob/main/sdk/api-reference/android/oninitcallback/broken-reference/README.md).

## OnInitCallback API

### `onInitFailure()`

> ```java
> void onInitFailure(InitIssue issue, @Nullable Throwable throwable)
> ```
>
> Called when an issue was encountered while initializing the SDK.

| Parameters |                                                                                                                                                                                                      |

### `onInitSuccess()`

> ```java
> void onInitSuccess()
> ```
>
