To check whether an app is installed on the device, call the `getApplicationDetails()` method.

{% code title="Kotlin" %}

```kotlin
fun getApplicationDetails(
data: String,
callback: IResponseCallback<AppDetailsResponse, Error, Progress>? = null,
metadata: Bundle = Bundle(),
action: Bundle = Bundle()
)
