I'm now listening to one of Ian Mccurdy's Csound Haiku, which use the signal flow graph opcode library's alwayson opcode, on my phone. This is a plugin opcode library.

In order to get plugin opcodes working for Csound 6 on Android, this is what I did:

(1) Copied all .so files and other .so files on which they depend (including the gnu stlport lib) into CsoundAndroid/libs/<arch> folders

(2) Set OPCODE6DIR to the native library dir of the app BEFORE Csound starts. This field is public since Android 2.3.3 which is SDK 10.

                                        String OPCODE6DIR = getBaseContext().getApplicationInfo().nativeLibraryDir;
// Set these BEFORE starting Csound.
csound.getCsound().SetGlobalEnv("OPCODE6DIR", OPCODE6DIR);
csound.getCsound().SetGlobalEnv("SSDIR", SSDIR);

(3) In CsoundAppActivity, use Java to preload these libs in order to debug the loading process. LuaJIT is still not loading, but I'm pretty sure it won't take much more to get it loading, it's the soname is wrong... This only works after the CsoundObj is created, and it only works after the first run which does not work. Still needs some debugging, but basically it works.

// Pre-load plugin opcodes, just to ensure that they 
// actually will load from Csound.
File file = new File(OPCODE6DIR);
File[] files = file.listFiles();
for (int i = 0; i < files.length; i++) {
String pluginPath = files[i].getAbsoluteFile().toString();
try {
CsoundAppActivity.this.postMessage("Loading Csound plugin:" + pluginPath);
System.load(pluginPath); 

} catch (Throwable e) {
Log.d("Csound6", e.toString());
}
}

That makes sense, because Csound will try to load plugins when it starts.

Hi Michael,

I was happy to read this email after getting back from my trip last
night. Fantastic!  Thanks very much for researching and figuring out a
solution for all this.

Looking forward to trying it out!
