# Handling System Permissions

> Detect and resolve missing system permissions like Bluetooth and connectivity in your mobile app by handling the Seam SDK's credential errors.

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.

***

## Platform Setup Requirements

First, configure the required platform capabilities.

<Tabs>
  <Tab title="iOS Swift">
    1. **Suppress Apple Wallet while unlocking with BLE**\
       To prevent the Apple Wallet dialog from appearing when your app uses BLE to unlock a door, do the following:

       * Add the `requestAutomaticPassPresentationSuppression()` call to your app.\
         This method suppresses Apple Wallet while your mobile app is in the foreground and ensures a smoother `unlockWithTap` experience.
       * Request the  `com.apple.developer.passkit.pass-presentation-suppression` entitlement from Apple.&#x20;

       Apple Wallet suppression and Bluetooth scanning only apply while the app is in the foreground. Ensure unlock operations are initiated while the app is active.

    2. **Enable Bluetooth capability**

       Add the required Bluetooth key to your app’s entitlements file:

       ```xml theme={null}
       <dict>
         <key>com.apple.security.device.bluetooth</key>
         <true/>
       </dict>
       ```
  </Tab>

  <Tab title="Android Kotlin">
    1. **Request Bluetooth permissions**

       Define and call a helper function in your app to request the necessary Bluetooth permissions at runtime.

    2. **For Android 12 (API 31) and newer:**

       ```
       Manifest.permission.BLUETOOTH_SCAN
       Manifest.permission.BLUETOOTH_CONNECT
       Manifest.permission.BLUETOOTH_ADVERTISE
       ```

    3. **For Android 11 (API 30) and older:**

       ```
       Manifest.permission.BLUETOOTH
       Manifest.permission.BLUETOOTH_ADMIN
       Manifest.permission.ACCESS_COARSE_LOCATION
       Manifest.permission.ACCESS_FINE_LOCATION
       ```

    See [Android request permissions](https://developer.android.com/training/permissions/requesting) for more details.

## Monitoring Permission Errors

<Tabs>
  <Tab title="iOS Swift">
    Use Combine to watch the published credentials array and handle permission-related errors:

    ```swift theme={null}
    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.
  </Tab>

  <Tab title="Android Kotlin">
    ```kotlin theme={null}
    coroutineScope.launch {
        SeamSDK.getInstance().credentials.collect { credentialsList ->
            val errors = credentialsList.flatMap { it.errors }
            errors.forEach { error ->
                when (error) {
                    is SeamCredentialError.UserInteractionRequired -> {
                        handleUserInteractionRequired(error.interaction)
                    }
                    else -> { /* handle other errors */ }
                }
            }
        }

        fun handleUserInteractionRequired(interaction: SeamRequiredUserInteraction) {
            when (interaction) {
                is SeamRequiredUserInteraction.GrantPermissions -> {
                     /* handle permissions error */
                     // interaction.permissions contains the list of required permissions
                }
                else -> { /* handle other errors */ }
            }
        }

    }

    ```

    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:

<CodeGroup>
  ```kotlin Android Kotlin theme={null}
  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*/ }
      }
  }
  ```

  ```swift iOS Swift theme={null}
  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.
      }
  }
  ```
</CodeGroup>
