# バックボタンでアプリ内メッセージを閉じることはできますか？

{% hint style="warning" %}
**ここでは Android 固有の事象について取り扱っております**
{% endhint %}

SDKではAndroid端末のバックボタンの操作に関して関与することはありません。\
そのためバックボタンの操作をトリガーにアプリ内メッセージを閉じたい場合は、独自に実装を行う必要があります。

**実装サンプル**

{% code overflow="wrap" %}

```java
@Override
public void onBackPressed() {
  if (InAppMessaging.isPresenting) {
    InAppMessaging.dismiss();
  } else {
    super.onBackPressed();
  }
}
```

{% endcode %}
