This is a simple demo application for GNU Radio on Android, implementing an FM receiver that works with the RTL-SDR and the HackRF.
Building the app requires the GNU Radio Android toolchain. Please see this repository for further instructions on how to build the toolchain.
The USB vender/product IDs and the device type (HackRF or RTL-SDR) are currently hardcoded. Please adapt native_lib.cpp
and MainActivity.kt
accordingly.
