While I have been talking around it for a while, I wanted to better publicize our work on GNU Radio for Android. We can now build applications that run GNU Radio flowgraphs on Android (\>= 5.0). We build the flowgraph in C++ and link it through to a Java app for the user interface using the JNI. I have tried to collect the howtos for getting all of the various parts up and running here: [http://gnuradio.org/redmine/projects/gnuradio/wiki/Android](http://gnuradio.org/redmine/projects/gnuradio/wiki/Android) Last week, we got UHD support working, and I felt this was a big marker in our progress on the project. To top it off, we now even have ControlPort support on Android apps, which makes it possible to provide remote control and run tools like gr-perf-monitorx, from which I’m already finding out new things about GNU Radio and Android device performance issues. There’s still a big warning about this being a work in progress, and it definitely is. However, with the support for all of the various hardware and tools that we now have, I think we’re at a place of usability for a lot of applications. Feel free to ask questions if things in the wiki don’t work for you. I’ve tried to go through it multiple times and make it as robust as possible and mostly things should be copy-and-paste. But as things change, and they do rapidly here, we’re likely to continue to need some evolution of the instructions. I will hopefully post some of my simple applications online sometime soon, as well. Tom ---

Wow, it’s so cool! I’ll have a try, following your wiki. -Lin 2015-05-06 4:06 GMT+08:00 Tom R. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid): ---

Hi, I’ve been trying the instructions in the wiki with ubuntu 15.04 and gcc 4.8 (4.9 also gave me problems). I got the following error checking out the android branch from git:// [git.gnuradio.org/gnuradio.git](http://git.gnuradio.org/gnuradio.git) error: The following untracked working tree files would be overwritten by checkout: volk/CMakeLists.txt … Aborting But it worked well with the repo: [GitHub - trondeau/gnuradio: GNU Radio](https://github.com/trondeau/gnuradio/) I also got an error compiling GRAnd. It seems to be related with boost, which I cross compiled following the instructions. I’ve attached the output of make, if anyone has the time to have a look at it it would be much appreciated.

I use the trondeau/gnuradio android branch as my staging area while working on new stuff. The one on gnuradio’s repo was prior to me rebasing off the latest master, which was before the volk submodule change. I’ve just updated gnuradio’s repo branch to the latest so we shouldn’t see this problem now. > I also got an error compiling GRAnd.

I’m wondering if it’s picking up a wrong version of Boost. You can force this by passing it -DBOOST\_ROOT=\. Just make sure that PREFIX is set correctly and Boost was installed into that same PREFIX.

I’ve left out PMT as a dependency. If you go into gr-grand/CMakeLists.txt file, change line 113 from: set(GR\_REQUIRED\_COMPONENTS RUNTIME VOLK) to set(GR\_REQUIRED\_COMPONENTS RUNTIME PMT VOLK) I have a feeling my system is picking up an outdated component check file because it’s pulling in libgnuradio-pmt.so for me as part of the RUNTIME check. Everything else looked good. Thanks for all the necessary details here. Let me know if this works for you and I’ll check in the patch. Also, what version of cmake are you using? Looks like there’s a lot of sloppiness in my cmake stuff for this project, and I’m guessing you’re using a newer version that’s throwing all of those warnings. I’ll try to clean that up, too. Thanks, Tom ---

I’ve attached the command used and the output of cmake. Thanks for your time. Murray 2015-05-09 15:10 GMT+01:00 Tom R. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid): ---

Thanks Tom, That change solved the problem and I managed to install it. I’m using cmake version 3.0.2. The change in the gnuradio repo also fixed my problem checking out the android branch. I appreciate you taking the time to help me with this problems so quickly, specially on a weekend. I’ll have to think about something cool to do with GnuRadio and Android now 🙂 Cheers, Murray 2015-05-09 17:58 GMT+01:00 Tom R.
