SDR on an Android 5.1.1 phone (OnePlus 2) using an "ezcap DVB-TFM DAB" dongle.
The app is called "RFAnalyzer" by Dennis Mantz, and is available for less than £1 (at time of writing) on the Google Play app store.
Source code can be found at https://github.com/demantz/RFAnalyzer.
I am thinking about writing some driver software to get the "SDRPlay RSP" receiver to work with this app, then this would really be fantastic for on the move listening.
