    if SmartDevice.HasPermission(PermissionOptions.Camera):
        labelResult.Text = "Camera permission granted!"
    else:
        labelResult.Text = "Camera permission denied!"
        SmartDevice.OpenAppSettings()

Example: Monitor Battery

when ClockBattery.Timer:
    labelBatteryLevel.Text = SmartDevice.GetBatteryLevel() + "%"
    labelBatteryTemp.Text = SmartDevice.GetBatteryTemperature() + "°C"
    if SmartDevice.IsCharging():

:bug: Troubleshooting

Permission Denied Errors

Some methods require specific permissions. Make sure to request them at runtime or check HasPermission() first.

Null or Empty Values

If a method returns an empty string, call GetLastError() to see what went wrong.

Bluetooth Issues on Android 12+

Bluetooth methods may require BLUETOOTH_CONNECT permission on Android 12+. Use HasPermission(PermissionOptions.BluetoothConnect) first.

Location Permission

IsLocationEnabled() requires location permission. Check with HasPermission(PermissionOptions.AccessFineLocation) first.
