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

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)
                }
            }
        }
    }
}

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:

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*/ }
    }
}
