Jetpack Compose is a new modern toolkit for building native UI for Android. One major difference in Jetpack Compose is the absence of `Activity`. The `purchasePackage()` and `purchasePackageWith()` functions accept an `Activity` as the first parameter but an `Activity` is not easily accessible in a `@Composable` function.

To get around this, you can create an extension function to recursively find the nearest `Activity` from your Jetpack Compose context.

```kotlin
fun Context.findActivity(): Activity? = when (this) {
    is Activity -> this
    is ContextWrapper -> baseContext.findActivity()
    else -> null
}
```

So example below shows how to check the nullable `Activity?` returned by `LocalContext.current.findActivity()` and pass it into `purchase(package:)`.

```kotlin
LocalContext.current.findActivity()?.let { activity ->
	Purchases.sharedInstance.purchaseWith(
		PurchaseParams.Builder(this, aPackage).build(),
    onError = { error, userCancelled -> /* No purchase */ },
    onSuccess = { storeTransaction, customerInfo ->
			if (customerInfo.entitlements["my_entitlement_identifier"]?.isActive == true) {
				// Unlock that great "pro" content
			}
    }
	)
}
```
