Thanks Tom, that sorted it out. My audio output is a bit choppy but no matter – time to move on to some more complex flowgraphs in my Android app.

I'm hitting a snag on the ndk-build step though -- when I use your example Android.mk listing, the linker isn't finding any of the static libraries we built (gnuradio, grand, boost, fftw.) Instead I'm getting a pile of undefined reference errors. I tried editing the example Android.mk file by adding the following before the shared library build: include $(CLEAR_VARS) LOCAL_MODULE := grand_static_lib #for example LOCAL_SRC_FILES := /opt/grandroid/lib/libgnuradio-grand.a include $(PREBUILT_STATIC_LIBRARY) However I quickly realised that while there are only a few gnuradio libraries to add this way, there are a ton of boost libraries... Is there a smarter way to add all the prebuilt .a libraries at once? Or am I headed in the wrong direction entirely? Any tips appreciated, Vijay Yep, you have to add all of the libraries into the Android.mk file. I've updated the wiki: http://gnuradio.org/redmine/projects/gnuradio/wiki/GRAndApps You can go there and simply download GrAndroid.mk that does all of this for you and include it in your Android.mk file. Just follow the instructions.

I'm working on a project where I'm transmitting information over audio from a desktop system to an Android device, and since setting up the transmitter end with GNU Radio was such a snap I would love to leverage the GNU Radio system to build the receiver as well. Thanks, Vijay Just yesterday, in fact: http://gnuradio.org/redmine/projects/gnuradio/wiki/Android I'll try to release some of my apps soon. One of them captures from the audio device, even. It's not too hard since there's the gr-grand opensl audio source block to talk to the audio system.
