The libfluidsynth opcode library is using a static link to
fluidsynth-android, which should build a .a. You will need to define
the NDK_MODULE_PATH to the pluginLibs folder.  (I think the variable
used to be set automatically in our build scripts, not sure why it
isn't now.)  Try setting that environment variable before building and
write back here if there's any issues.

Also, fluidsynth-android certainly has a jni folder:

https://bitbucket.org/kunstmusik/fluidsynth-android/src/master/

Maybe there was a bad checkout? Try rm -rf that folder in pluginLibs
and try re-running downloadDependencies.sh.

I've checked the file exists in the provided path and I can successfully open a .csd file on the same directory, so I think permissions are ok.

I have entered an issue in my csound-extended repository to debug this.

I can reproduce the issue. Everything is fine up until the SoundFont
is loaded, then the Csound for Android app just crashes without any
informative messages.

I know that I can run a .csd that plays a sample soundfile if it is
stored in my public data directory, and I also have all the files I am
trying to use to play the SoundFont, including the SoundFont file, in
the same public data directory.

I have released a new version of the Csound for Android app in my
csound-extended repository here:
https://github.com/gogins/csound-extended/releases/tag/v1.3.4.

This release fixes the SoundFont crash, has a new example using
SoundFonts, and has 9 preconfigured sliders instead of 5. The
orientation of the sliders is fixed.

If there are no new issues with this I will post it to the Google Play
Store in the next few days.

Regards,
Mike
