Unable to load liblivekit_ffi.so on android arm 64

[holofermes]

The new liblivekit_ffi.so is not loading on an android phone with arm 64 architecture - I tried on a Samsung S22, and an S24.

This is the error reported by Unity:

Unity LiveKit: System.DllNotFoundException: Unable to load DLL 'livekit_ffi'. Tried the load the following dynamic libraries: Unable to load dynamic library 'livekit_ffi' because of 'Failed to open the requested dynamic library (0x06000000) dlerror() = dlopen failed: library "livekit_ffi" not found

Kind of stabbing in the dark here, but this is what ldd returns on the .so file:

        linux-vdso.so.1 => [vdso] (0x7020c80000)
CANNOT LINK EXECUTABLE "linker64": cannot locate symbol "__assert_fail" referenced by "/data/app/my-apk/lib/arm64/liblivekit_ffi.so"...

And this is what readelf -d returns:

 0x0000000000000001 (NEEDED)             Shared library: [libm.so]
 0x0000000000000001 (NEEDED)             Shared library: [libEGL.so]
 0x0000000000000001 (NEEDED)             Shared library: [libdl.so]
 0x0000000000000001 (NEEDED)             Shared library: [liblog.so]
 0x0000000000000001 (NEEDED)             Shared library: [libc.so]

The previous .so works fine, ldd resolves all the dependencies, and readelf -d shows:

 0x0000000000000001 (NEEDED)             Shared library: [libm.so]
 0x0000000000000001 (NEEDED)             Shared library: [libEGL.so]
 0x0000000000000001 (NEEDED)             Shared library: [libOpenSLES.so]
 0x0000000000000001 (NEEDED)             Shared library: [libdl.so]
 0x0000000000000001 (NEEDED)             Shared library: [liblog.so]
 0x0000000000000001 (NEEDED)             Shared library: [libc.so]

It looks like the libOpenSLES.so dependency is missing from the new .so file.

Just updated from Livekit 1.0.1 to the latest 1.2.0. Having the same issue running on the Magic Leap 2 (Android).

This did not occur in 1.0.1

[ladvoc]

Thank you both for reporting, I will take a look to see what's going on.

[ladvoc]

Two follow-up questions:

1. What version of Android are you deploying to?
2. What version of Unity are you building with?

[KarlSupertramp]

@ladvoc

I'm deploying for Android API level 29 with Unity version 6000.0.44f1

[WaN9Bro]

I just encountered this problem when I upgraded from version 1.1.0 to version 1.2.0. The Unity version is 2021.3.48f1

@ladvoc

Just tried it with the latest 1.2.1, the same issue still occurs:

Android API level 29 (x86_64) / Unity version 6000.0.44f1 / Device: Magic Leap 2

[yu-jinh]

I am developing on Meta Quest3 and have the same issue on v1.2.1.

This problem appear when I update from v1.1.0 to v1.1.1.

Android API level 32/ Unity version 2022.3.47f1 (same issue on 6000.0.37f1) / Device, Meta Quest3

[ladvoc]

I have determined the automated build process which generates liblivekit_ffi.so for Android is broken, resulting in a library that cannot be loaded in Unity. This issue will be resolved in an upcoming patch release. Thank you for reporting.

There are any update about this problem?
I'm trying to build my solution on Android and when try to connect the Room, it give me the same output error.

The problem still persists when building on MacBook Pro Apple M4 Pro directly to android phone: DllNotFoundException: Unable to load DLL 'livekit_ffi'. Tried the load the following dynamic libraries: Unable to load dynamic library 'livekit_ffi' because of 'Failed to open the requested dynamic library (0x06000000) dlerror() = dlopen failed: library "livekit_ffi" not found at LiveKit.Internal.NativeMethods.LiveKitInitialize (LiveKit.Internal.FFICallbackDelegate cb, System.Boolean captureLogs, System.String sdk, System.String sdkVersion) [0x00000] in <00000000000000000000000000000000>:0 at LiveKit.Internal.FfiClient.InitializeSdk () [0x00000] in <00000000000000000000000000000000>:0. See screenshots to see current Plugins folder and the inspector of Liblivekit_ffi and livekit_ffi:

Is something done wrong?

[thedrhax14]

I tried on windows and it worked but at first it didn't and it was the same error. With the same setup I just completely deleted the app from my phone and did clean installation and Dll exception doesn't occur. There is a different problem now but it is related to livekit server config.

I am still not sure what exactly fixed the issue.

having this same issue right now with 1.2.2 and unity 6000.1.4f1 building for my meta quest 3. are there any updates on this? i've tried uninstalling and rebuilding already to no avail

Working with ChatGTP, I tried to build the application via Android Studio, importing the file .so directly in the assets project.

The application manages to load the file but crashes, according to Android Logcat this is due to an incorrect generation of the liblivekit_ffi.so file which lacks the x64 architecture.

ChatGTP suggested me to directly generate a .so file with the correct architecture using the LIveKit rust project: https://github.com/livekit/rust-sdks/tree/main

Unfortunately despite my countless attempts I can't generate the file due to an error during generation. I honestly don't know how to solve it
