### Install the package

<CodeGroup>
  ```groovy title={"Groovy"} theme={null}
    implementation 'com.launchdarkly:launchdarkly-android-client-sdk:5.+'

  ```

  ```kotlin title={"Kotlin"} theme={null}
    implementation("com.launchdarkly:launchdarkly-android-client-sdk:5.+")

  ```
</CodeGroup>

The SDK uses [AndroidX from Jetpack](https://developer.android.com/jetpack/androidx). If your project does not use AndroidX,
read [Android's migration guide](https://developer.android.com/jetpack/androidx/migrate).

### Initialize the SDK

```kotlin title={"Android SDK initialization"} theme={null}
import com.launchdarkly.sdk.*
import com.launchdarkly.sdk.android.*;

val ldConfig = LDConfig.Builder(AutoEnvAttributes.Enabled)
    .mobileKey("YOUR_MOBILE_KEY")
    .build()

// A "context" is a data object representing users, devices, organizations, and other entities.
val context = LDContext.create("EXAMPLE_CONTEXT_KEY")

// If you don't want to block execution while the SDK tries to get
// latest flags, move this code into an async IO task and await on its completion.
val client: LDClient = LDClient.init(this@BaseApplication, ldConfig, context, 5)

```
