**Current SDK Version: 3.66.1**

DT Offer Wall and DT FairBid are integrated through the same SDK: the DT FairBid SDK. Apps with an existing FairBid integration can proceed directly to the [Offer Wall Configuration](https://docs.digitalturbine.com/dt-offer-wall/publishers/dt-offer-wall-sdk/sdk-apis).
{% endhint %}

## Prerequisites

| PLATFORM             | REQUIREMENT                           |
| -------------------- | ------------------------------------- |
| Android API          | Android 4.4 (API Level 19) and later. |
| Kotlin               | 2.1.0 and later.                      |
| Google Play Services | 11.4.0 and later.                     |

### Tooling

FairBid SDK does not require specific tooling, for example, Android Studio, Android Gradle Plugin (AGP), Java Development Kit (JDK), and Gradle. However, if you use the following versions of Gradle, use the corresponding versions of AGP and JDK:

| GRADLE        | AGP         | JDK |
| ------------- | ----------- | --- |
| 7.5 and later | 7.4.2       | 11  |
| 8 and later   | 8 and later | 17  |

### Compile and Target SDK

FairBid SDK does not require specific compile or target SDK versions for your app. It maintains compatibility by performing runtime checks for APIs that are not available in the minimum supported version (API Level 19). The highest Android API that FairBid directly utilizes is API Level 30.

## Integration

DT supports both Gradle dependencies and manual downloads to integrate the SDK.

### Gradle

Add DT Maven repository and plugins to your Gradle build script:

1. Add the following to your project's root-level `build.gradle` file inside the `repositories` section.
2. At the root level `build.gradle` file, there are usually two repository sections — one for `buildscript` and one for `allprojects`. Add the entry in `allprojects`:

{% code title="Groovy" %}

```groovy
allprojects {
    repositories {
        mavenCentral()
    }
    ...
}
```

{% endcode %}

3. Add the following to the project app-level `build.gradle` file inside the `plugins` section. For more information, see [Types of Gradle Plugins](https://docs.gradle.org/current/userguide/plugins.html#sec:plugins_block):

{% code title="Groovy" %}

```groovy
plugins {
    ...
    id 'com.fyber.fairbid-sdk-plugin' version '3.66.1'
    ...
}
```

{% endcode %}

4. If you support Android SDK 26 and earlier, add the following snippet to the `android` section (for Java Version Compatibility):

{% code title="Groovy" %}

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

{% endcode %}

### Manual Download

1. Download the DT FairBid SDK.
2. Extract the file.
3. Import the `.aar` packages into your project.
