Handling System Permissions

The mobile SDK surfaces missing or required system permissions (Bluetooth, internet connectivity, and so on) as CredentialError.userInteractionRequired(action) entries in each credential’s errors array. After activation, observe these errors and handle the specified actions. Errors update automatically as requirements change.

Monitoring Permission Errors

Android Kotlin

coroutineScope.launch {
    SeamSDK.getInstance().credentials.collect { credentialsList ->
        val errors = credentialsList.flatMap { it.errors }
        errors.forEach { error ->
            when (error) {
                is SeamCredentialError.Expired -> { /* handle credential expiration error */}
                is SeamCredentialError.Loading -> { /* handle not loaded yet */ }
                is SeamCredentialError.Unknown -> { /* handle unknown error */}
                is SeamCredentialError.UserInteractionRequired -> {
                    handleUserInteractionRequired(error.interaction)
                }
            }
        }
    }
}

iOS Swift

Use Combine to watch the published credentials array and handle permission-related errors:

import SeamSDK
import Combine

func startMonitoringPermissionErrors() {
    permissionCancellable = Seam.shared.$credentials
        .map { credentials in
            credentials.flatMap { credential in
                credential.errors.compactMap { error in
                    guard case .userInteractionRequired(let action) = error else { return nil }
                    return action
                }
            }
        }
        .receive(on: RunLoop.main)
        .sink { actions in
            actions.forEach { handlePermissionAction($0) }
        }
}

The mobile SDK automatically clears resolved permission errors once the required permission is granted, reflecting the updated credential state.

Handling Permission Actions

Implement your handler for each action:

Android Kotlin

fun handleUserInteractionRequired(interaction: SeamRequiredUserInteraction) {
    when (interaction) {
        is SeamRequiredUserInteraction.CompleteOtpAuthorization -> { /* handle OTP authorization */ }
        is SeamRequiredUserInteraction.EnableBluetooth -> { /* handle Bluetooth error */ }
        is SeamRequiredUserInteraction.EnableInternet -> { /* handle Internet connection error*/ }
        is SeamRequiredUserInteraction.GrantPermissions -> { /* handle permissions error*/ }
    }
}

iOS Swift

func handlePermissionAction(_ action: CredentialUserAction) {
    switch action {
    case .enableInternet:
        // Prompt the user to enable network connectivity.
    case .enableBluetooth:
        // Prompt the user to turn on Bluetooth.
    case .grantBluetoothPermission:
        // Prompt the user to grant Bluetooth permission in Settings.
    }
}
