Yes! Nice, Rory. It'll be interesting to see what happens when more
people get the opportunity of flexible sound design in games.

This is pretty great. I've been coding games and Csound for, well, a long
time now and I've always wanted to combine the two.

Lately, I've been trying to get the Csound library working in Android Studio
with LibGDX: a Java game engine, but I keep getting
java.lang.NoClassDefFoundError: csnd6.csnd

I'm using the .jars you uploaded here:
http://csound.1045644.n5.nabble.com/Compiling-csound6-04-Sample-CSDPlayer-in-ANDROID-STUDIO-td5740225.html
and found some information on getting past NoClassDefFound errors here:
http://stackoverflow.com/questions/17724642/android-studio-java-lang-noclassdeffounderror
and I think I've almost got it cracked. Still not working, but close. Soon!!

I'm very interested to hear how that turns out. The few times I messed with
it, I never liked Unity a whole lot, but if Csound happens to work in it, I
might be tempted to pick it back up.

I've got AndroidCsound imported, compiling and running with LibGDX in
Android Studio now, but it won't make any sound, nor report any errors.
Slowly losing my mind.

I set -odac in the CsOptions in the csd file.

I have now setOpenSlCallbacks (Thanks for that!!) and it tells me "Failed to
open csd file: No such file or directory".

The Android portion of a LibGDX project sets the working directory to
android/assets which is where I've put my csd file, but I imagine
csound.CompileCsd("csoundFile.csd") isn't finding it because... I don't
know, I'm not really a very good coder, but my guess is that the Csound API
doesn't use or see LibGDX's default asset folder.

I'm trying to find out how to fix the path now...

Now I'm completely mystified because I'm passing the csd file as a string to
.CompileCsd and the error is still "Failed to open csd file: No such file or
directory" which says to me that CompileCsd wants a file name or nothing.

Could the fault lie in CompileCsd because in the example you linked, he
separates his Orc and Sco and that's a habit I tried very hard to get rid of
when Csound 5 came along... XP

Well, I split my csd string into separate ORC and SCO strings and compiled
them separately with CompileOrc and ReadScore and it /somehow /worked and I
heard the most lovely 10 second long 1kHz sin wave I've ever heard in my
life come out of my shoddy phone speaker and I'm the happiest I've ever been
in my life.

If anyone is interested in the process of getting the Csound API working
with LibGDX in Android Studio, well, I'm not sure I can reproduce it, but
feel free to ask.

Now to make it actually interactive.

Correct, file name or nothing.

There's more, csds can use t,s,e, and score expressions but ReadScore can't, and all times are seconds.

Regards,
Mike

There's no problems to use CSD's. The examples project that comes with
the Csound for Android SDK demonstrates this:

A LibGDX project doesn't have the getResourceFileAsString() nor
createTempFile() methods from the BaseCsoundActivity class. LibGDX also
doesn't manage resources the same way the default Android activity does.

There are methods in LibGDX that return Java.io.File types from internal
assets. I'll give that a shot with my csd and try passing that to
CompileCsd.

All java classes have something along the lines of: getClass().getResourceAsStream(filename)

If you place your csd file alongside your java sources, and get the builder to copy the file when building, you should see it sitting alongside the compiled java class files. This should work, 
I've done it many times using the desktop JDK

All the best,

Jacques

LibGDX does indeed have getResourceAsStream(), but now I don't exactly know
what to do with that stream...

Well, I got it working.

It was a problem of how Android and LibGDX handle file storage.

LibGDX deals with assets in what it calls "internal" storage, which are
read-only because - it being a game engine - you typically don't need to
change textures or sound files on the fly. It also has what it calls "local"
storage which are files that you can read from and write to. All of this is
because of the way Android deals with memory management I guess.

I had a lot of trouble trying to get a local file packed with the apk that
Studio generates, so, I ended up packing the csd file as an internal file,
then writing the InputStream from that to a temp.csd local file, which I
then have to use LibGDX's FileHandle .file() method on to turn it into a
Java.io.File type to pass to csoundObject.startCsound().

Thanks for the tips everyone! I'll post some links once (if) I ever publish
an app.

There are many java io classes that take an InputStream to facilitate reading from the stream, or you can just read from the input stream inside a loop. Appending each character to a stringbuilder. 

When all is read, stringbuilder.tostring() should give you the contents as a string


All the best
