我们希望访问所有的无线电频率附近可用的Andr​​oid设备。是否有任何的API可用于相同？我们可以扫描频率不附带耳机，考虑到有些收音机将无法启动无耳机（作为天线）？

我们要访问的所有酒店附近的Andr​​oid设备的无线电频率。是否有任何的API可用于相同的。

不是标准的Andr​​oid。

由于我们有收音机内置在设备中必须有一些可用的API，用于扫描站

我冒昧的Andr​​oid设备的不足1％有任何形式的电台，有站的。如果你碰巧有一个具有AM，FM，短波，或类似一种无线的设备，欢迎您咨询该设备的制造商，看看他们是否有某种方式来让你控制它。

We want to access all the radio frequencies available near Android device. Is there any API available for the same? Can we scan frequency without attaching headphones, given that some radios won't start up without the headphones (used as an aerial)?

We want to access all the radio frequencies available near android device. Is there any API available for the same.

Not in standard Android.

Since we have radio inbuilt in the device there must be some API available for scanning the stations

I would venture that less than 1% of Android devices have any sort of "radio" that has "stations". If you happen to have a device that has an AM, FM, shortwave, or similar sort of "radio", you are welcome to contact the manufacturer of that device to see if they have some sort of means to allow you to control it.
