Reading through the codebase, I think there's a lot of potentially unnecessary extra complexity here. Instead of trying to manage what the native integer type is, why not use std::ffi::c_char which maps to whatever is platform appropriate & then you can get rid of all the i8/u8 platform-specific mappings.

Thanks @vlovich

I created #78

Do you know if I can simplify the way I pass and free strings from Rust to C as well? -

Here I store them in variable so they won't free until the end of the scope

@oddpxl

I released new version, if the issue persists feel free to reopen the issue

vlovich · 2025-01-19T17:22:14Z

@thewh1teagle if I'm not mistaken, the RawCString class isn't really doing anything extra on top of CString and call .as_ptr to retrieve the pointer. So I think you could just get rid of RawCString use CString directly rather than leaking/restoring ownership.

On an unrelated note, I wanted to point out that the recognizer API takes in an owned Vec but that implies you need far more ownership than you need since the Sherpa API only uses the contents for the duration of the transcribe API and not any longer. When ownership of something is contained within a function call, it's a better practice to accept a reference to the most generic type that meets your needs. In this case it would be &[f32] since you only need a slice of audio samples regardless of how externally they're stored (similar to how you'd accept a &str instead of String/&String if the string's lifetime is only needed for the duration of the function)

pnpm tauri android dev and build now works ! yay !

..however my app crashes - and after some adb logcat squinting I find ...

"AndroidRuntime: java.lang.UnsatisfiedLinkError: dlopen failed: library "libsherpa-onnx-c-api.so" not found: needed by /data/app/~~tBCrXNhgm4UdkNwlHficCw==/com.odd.dev-zmNYNjfdO8zF-zKo3_ujGA==/base.apk!/lib/arm64-v8a/libtauri_mobile_neo_lib.so in namespace clns-7 "

Not sure if I did something wrong in my setup - but it seems it can't find libsherpa-onnx-c-api.so

I can see there's a link...
/src-tauri/gen/android/app/src/main/jniLibs/arm64-v8a/libtauri_mobile_neo_lib.so

..that leads to...
/src-tauri/target/aarch64-linux-android/release/libtauri_mobile_neo_lib.so

So it looks like all should be fine ?

Yet logcat says it can't find the file when running the app ( dev and build )

Any ideas ?

Opened the issue here --> #79

if I'm not mistaken, the RawCString class isn't really doing anything extra on top of CString and call .as_ptr to retrieve the pointer. So I think you could just get rid of RawCString use CString directly rather than leaking/restoring ownership.

I created it to centeralize the logic of how actually get the pointer for the cstring and drop it, with potential to improve it in one place.

Can you show me which recognizer you reffered to?

           ],

You need to make sure that these shared libraries available in runtime in the Android. usually you need to place them in the Android JniLibs/ (Google/LLM it)

oddpxl · 2025-01-19T22:00:22Z

YES !

App no longer crashes !

There's only a symlink for for libtauri_mobile_neo_lib.so ( not the other two ) in
/src-tauri/gen/android/app/src/main/jniLibs/arm64-v8a
/src-tauri/gen/android/app/src/main/jniLibs/arm64-v7a

so I copied
libonnxruntime.so
libsherpa-onnx-c-api.so

from
/src-tauri/target/aarch64-linux-android/release/
/src-tauri/target/armv7-linux-androideabi/release/

to
/src-tauri/gen/android/app/src/main/jniLibs/arm64-v8a
/src-tauri/gen/android/app/src/main/jniLibs/arm64-v7a

..and now it works.

That said - my VAD no longer initialise... ..so perhaps some VAD bundling problem ( on my side ) - looking at that now.

I created it to centeralize the logic of how actually get the pointer for the cstring and drop it, with potential to improve it in one place.

I get that. I'm just highlighting that CString already does that. It's possible you're planning additional capabilities for the class, just saying right now it's identical to CString with no extra functionality unless I'm misreading the code.

Re the recognizer, I was working with the whisper recognizer.

Yes currently that's all it does
The thing is that the only reason that pointer remain valid and freed only after sherpa used it, is the fact that I hold it in variable and it's dropped in the end of the scope
If I would create and pass it directly there was undefined behavior (I think it's freed immediately)
So that's a bit risky in Rust and weird way to make sure it's freed only in the end of the scope

vlovich · 2025-01-20T02:25:48Z

CString is literally that - when the reference drops the memory is freed. Are you perhaps confusing it with CStr which is like str?
