Exception thrown when a network operation cannot be completed due to network unavailability.

This exception is specifically used to distinguish network unavailability issues from other types of exceptions that might occur during API operations. When this exception is thrown, the SDK can decide whether to queue the request for later retry based on the current configuration settings.

try {
    val campaign = apiClient.postActivity(materialId)
} catch (e: NetworkUnavailableException) {
    // Handle network unavailability - possibly queue for retry
    pendingRequestManager.addPendingRequest(materialId)
}
