# Добавление SDK в проект

В `build.gradle` проекта добавьте строки:

```groovy
allprojects {
  repositories {
    maven { url "https://ozforensics.jfrog.io/artifactory/main" }
  }
}
```

В `build.gradle` модуля добавьте строки (VERSION – версия, которую вы планируете добавить. Список версий можно найти в [Журнале изменений](/oz-knowledge-ru/rukovodstva/rukovodstvo-razrabotchika/sdk/oz-mobile-sdk/android/zhurnal-izmenenii.md)):

```kotlin
dependencies {
  implementation 'com.ozforensics.liveness:sdk:VERSION'
}
```

Добавьте также:

```java
android {
  compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
  }
}
```

Начиная с версии 8.18.0, вы можете вынести SDK в модуль Google Dynamic Feature и загружать по требованию. Поскольку основную часть размера SDK составляют нативные `.so`-файлы, перенос всего взаимодействия с SDK в отдельный модуль заметно уменьшает размер основного приложения.

Для этого SDK предоставляет колбэк `onContextAttachListener`, который вызывается из `attachBaseContext` внутри Activity нашего SDK — в нём вы можете вызвать `SplitCompat.installActivity()`:

{% code title="" expandable="true" %}

```kotlin
OzLivenessSDK.config.onContextAttachListener = object : OnContextAttachListener {
    override fun onContextAttached(context: Context) {
        SplitActivity.installActivity(this)
    }
}
```

{% endcode %}

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://doc.ozforensics.com/oz-knowledge-ru/rukovodstva/rukovodstvo-razrabotchika/sdk/oz-mobile-sdk/android/dobavlenie-sdk-v-proekt.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
