# Съемка видео

Для старта записи видео используется метод `startActivityForResult`:

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

```kotlin
val intent = OzLivenessSDK.createStartIntent(listOf(OzAction.Smile, OzAction.Blank))
startActivityForResult(intent, REQUEST_CODE)
```

{% endtab %}

{% tab title="Java" %}

```java
List<OzAction> actions  = Arrays.asList(OzAction.Smile, OzAction.Scan);
Intent intent = OzLivenessSDK.createStartIntent(actions);
startActivityForResult(intent, REQUEST_CODE);
```

{% endtab %}
{% endtabs %}

`actions` – перечень [действий пользователя](https://doc.ozforensics.com/oz-knowledge-ru/rukovodstva/rukovodstvo-razrabotchika/sdk/oz-mobile-sdk/android/pages/GlyZwHmfP4TpgDOnHlBh#h.2nyke2meu4aw) при записи видео.

Для представления Fragment код приведен ниже. `LivenessFragment` – [Fragment](https://developer.android.com/guide/fragments) для экрана Liveness.

{% hint style="warning" %}
Для корректной работы лицензии мы рекомендуем сначала инициализировать SDK, и только потом вызывать открытие экрана Liveness.
{% endhint %}

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

```kotlin
childFragmentManager.beginTransaction()
    .replace(R.id.content, LivenessFragment.create(actions))
    .commit()
// подписка на результат Fragment
childFragmentManager.setFragmentResultListener(OzLivenessSDK.Extra.REQUEST_CODE, this) { _, result ->
    when (result.getInt(OzLivenessSDK.Extra.EXTRA_RESULT_CODE)) {
        OzLivenessResultCode.SUCCESS -> { /* запуск анализа */ }
        else -> { /* вывод ошибки */ }  
    }
}
```

{% endtab %}

{% tab title="Java" %}

```java
getSupportFragmentManager().beginTransaction()
        .replace(R.id.content, LivenessFragment.Companion.create(actions, null, null, false))
        .addToBackStack(null)
        .commit();
// подписка на результат Fragment
getSupportFragmentManager().setFragmentResultListener(OzLivenessSDK.Extra.REQUEST_CODE, this, (requestKey, result) -> {
            switch (result.getInt(OzLivenessSDK.Extra.EXTRA_RESULT_CODE)) {
                case OzLivenessResultCode.SUCCESS: {/* запуск анализа */}
                default: {/* вывод ошибки */}
            }
        });
```

{% endtab %}
{% endtabs %}

Для получения результатов записи видео используется метод `onActivityResult`:

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

```kotlin
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
  super.onActivityResult(requestCode, resultCode, data)
    if (requestCode == REQUEST_CODE) {
      sdkMediaResult = OzLivenessSDK.getResultFromIntent(data)
      sdkErrorString = OzLivenessSDK.getErrorFromIntent(data)
    }
}
```

{% endtab %}

{% tab title="Java" %}

```java
@Override
protected void onActivityResult(int requestCode, int resultCode, @androidx.annotation.Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_CODE) {
        List<OzAbstractMedia> sdkMediaResult = OzLivenessSDK.INSTANCE.getResultFromIntent(data);
        String sdkErrorString = OzLivenessSDK.INSTANCE.getErrorFromIntent(data);
    }
```

{% endtab %}
{% endtabs %}

* `sdkMediaResult` – объект с результатами записи видео ([OzAbstractMedia](https://doc.ozforensics.com/oz-knowledge-ru/rukovodstva/rukovodstvo-razrabotchika/sdk/oz-mobile-sdk/android/pages/GlyZwHmfP4TpgDOnHlBh#h.s2ye0si7dzc2)) для дальнейшего использования при взаимодействии с Oz API.
* `sdkErrorString` – описание [ошибок](/oz-knowledge-ru/rukovodstva/rukovodstvo-razrabotchika/sdk/oz-mobile-sdk/android/metody-i-polya-android-sdk.md#vozmozhnye-oshibki) в случае их возникновения.

{% hint style="info" %}
Если наш SDK используется только для съемки, пропустите шаг "Выполнение проверок".
{% endhint %}

Если пользователь прервет запись видео (закроет экран), `resultCode` примет значение `Activity.RESULT_CANCELED`.

Пример кода для обработки:

```kotlin
when (resultCode) {
    Activity.RESULT_CANCELED -> *USER CLOSED THE SCREEN*
    OzLivenessResultCode.SUCCESS -> {
        val sdkMediaResult = OzLivenessSDK.getResultFromIntent(data)
        *SUCCESS*
    }
    else -> {
        val errorMessage = OzLivenessSDK.getErrorFromIntent(data)
        *FAILURE*
    }
}
```

## 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://doc.ozforensics.com/oz-knowledge-ru/rukovodstva/rukovodstvo-razrabotchika/sdk/oz-mobile-sdk/android/semka-video.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.
