windows-phone – Windows Phone 8中的FM收音机怎么了？

FM Radio是 Windows Phone 7中的强制性硬件要求,但它不存在于任何当前的Windows Phone 8设备上.
为什么WP8中的Music Hub没有FM收音机？我们至少可以使用 FMRadio API吗？

解决方法

根据MSDN：

Windows Phone 8 does not support the FM radio feature. If you use the
FM radio API in a Windows Phone 8 app,a RadiodisabledException will
occur.

也是从我听到的：

…the FM radio feature was planned to be included but got cut from this
release due to stability vs. time constraints.
(… I don’t kNow if
there are any plans to re-enable this feature in a future update.)

您可以使用此测试来安全地确定FMRadio是否可以在当前手机上使用：

/// <summary>
/// Flag is radio device is available in this phone.
/// </summary>
public bool IsRadioAvailable
{
    get
    {
        if (!radioInitialized)
        {
            radioInitialized = true;
            try
            {
                radio = FMRadio.Instance;
                isRadioAvailable = true;
            }
            catch (RadiodisabledException e)
            {
                isRadioAvailable = false;
            }
        }
        return isRadioAvailable;
    }
}
private bool radioInitialized;
private bool isRadioAvailable;

private FMRadio radio;

更新：
According to various sources FM广播将在即将到来的2013年夏季到来的Windows Phone 8更新中启用.
