Re: [Discuss-gnuradio] Some Detailed Questions about GNURadio GrRxFM Project On Android

[West, Nathan]

Hi Charlie,

It's been a while since I've touched Java/Android stuff, but those are ControlPort functions (part of the GNU Radio API). To use them they have to be wrapped by the JNI which looks like it was done with https://github.com/trondeau/GrRxFM/blob/master/controlport/src/main/java/gnuradio.thrift#L103 They are RPC service calls that Thrift should build actual code for as part of your app build process.

My guess from what I remember working with this is that you have to set up your gradle/whatever the "project" build system is called now correctly so that your app gui/main thread can see those service definitions.

Hello every friend,

Could I spare you a few minutes? :) My Teammates and I have learned to develop an application using B200mini on Android. We followed Mr.Trondeau instructions on http://gnuradio.org/redmine/projects/gnuradio/wiki/Android that very helpful for our work. Thank you very much.

Here are some questions to ask. I would be greatly appreciated if you can reply them.

We study the code of GrRxFM project which download from https://github.com/trondeau/GrRxFM and find that some lines of codes in OnDraw() function in SampleView.java are commented. We guess these codes can realize the function that get raw data from flowgraph. However, we cannot find the implementation of some key functions. Could you please give some explanations or some details about these functions and variables.

/////////////////////////////////////

Extracted from SampleView.java

mGraph.postGetKnob(a);

        

RunGraph.CPHandlerGet h = mGraph.mControlPortThread.getHandlerGet();

        

HashMap<String, RPCConnection.KnobInfo> k = h.getKnobs();

////////////////////////////////////

Rungraph.CPHandleGet, how to define this class? 

mGraph.mControlPortThread.getHandlerGet() how to realize this member function?

and h.getKnobs()  how to realize this member function?

We confused by these questions for some weeks and we would be greatly appreciated if you can reply them.

Thank you very much!

sincerely Charlie
