FMRadio.PowerMode Property

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Sets the RadioPowerMode of the device. Setting this property turns the device radio on or off.

Namespace:  Microsoft.Devices.Radio
Assembly:  Microsoft.Phone (in Microsoft.Phone.dll)

public RadioPowerMode PowerMode { get; set; }

When your application is deactivated, such as when receiving a Deactivated event, the radio will not stop playing automatically. As a best practice, set PowerMode to 'off' when your application is deactivated, to prevent background playback.

Caution noteCaution:

FM radio is supported only in apps that target Windows Phone OS 7.1. If you use the FMRadio class in apps that target Windows Phone OS 8.0 or later, a RadioDisabledException indicates that the FM radio feature is not available. On Windows Phone 8 devices with a build of 8.0.10322 or greater, the run-time exception may not occur if you use the FMRadio API. However, the FMRadio API is not supported for apps that target Windows Phone OS 8.0.

Supported in: 8.1, 8.0, 7.1, 7.0
