# Close SDK (Android only)

When done with Purchasely, you should call `close()` to remove all references to your activities. This method must only be called when you won't be using our SDK in the current user session. If you need to use our SDK again after calling `close()` then you need to call `Purchasely.Builder()` and `Purchasely.start()`.

For example you can call this method in the `onDestroy()` method of your main activity

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

```kotlin
override fun onDestroy() {
    super.onDestroy()
    Purchasely.close()
}
```

{% endtab %}

{% tab title="Java" %}

```java
@Override
protected void onDestroy() {
    super.onDestroy();
    Purchasely.close();
}
```

{% endtab %}

{% tab title="ReactNative" %}

```
Purchasely.close();
```

{% endtab %}

{% tab title="Cordova" %}

```
Purchasely.close();
```

{% endtab %}

{% tab title="Flutter" %}

```dart
Purchasely.close();
```

{% endtab %}
{% endtabs %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://purchasely.gitbook.io/purchasely/quick-start-1/sdk-configuration/config-appendices/close-sdk-android-only.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
