Rtl-sdr driver File Transfer app for Android description
Allows you to use I/Q packet source in your Android applications.
All you need is to launch an intent in the form iqsrc://rtl_tcp_arguments
where you replace rtl_tcp_arguments
with the arguments that you want your application to run rtl_tcp with and the magic will be done behind the scenes.
This driver could be used by third party applications to implement Software Defined Radio.
It does not require root for Android 3.1 and above.
