JNA problems

[Maivand]

I get this error directly after downloading the code trying to demo it.

Please add jna to dependencies

implementation 'net.java.dev.jna:jna:5.8.0@aar'

This should be fixed in https://github.com/alphacep/vosk-android-demo/commit/443b293e623dfd8753196c67a0dc3231f6839993

Thanks, that was fast! Unfortunately, it did not fix everything for me, I now cannot build instead due to a "duplicate class".

Execution failed for task ':app:checkDebugDuplicateClasses'.

     .... (and many more)

The same happens when using 5.8.0, as suggested in https://github.com/alphacep/vosk-api/issues/1277 (thanks for the link, though, I was thinking I had seen this somewhere before!).

[nshmyrev]

Ok, I need to investigate more I suppose

[xekl]

Thank you for looking into this! The suggestions I find online mostly consist of using gradle's "exclude group" feature

{
    exclude group: "net.java.dev.jna", module: "jna"
}

but this does not seem to work for implementation project(':models') whose LibVosk model apparently uses the "duplicate" JNA.

[nshmyrev]

check contents of apk file, does it include jna libraries?

[xekl]

According to Android Studio's APK viewer, yes, I think so:

[nshmyrev]

Thats strange, it seems to include some unrelated architectures, it should have armv7 instead, not darwin. How come so?

[nshmyrev]

Take a look inside https://repo1.maven.org/maven2/net/java/dev/jna/jna/5.13.0/jna-5.13.0.aar for example

I don't know and I don't know how to find out. Maybe it has something to do with me working on a Mac? Something under the hood that gradle just "manages" without asking?

[nshmyrev]

@xekl I've just released 0.3.47 and pushed a dependency update here. Could you please update and check?

[xekl]

Yes, it works now with the new version. Awesome, thanks for the troubleshooting!

[nshmyrev]

Ok, good

[Maivand]

Ill give it a try later tonight to see if it works for me aswell.

0.3.47

Where is the 0.3.47 version? Neither in release nor in tags...

[nshmyrev]

@zooyf in maven

https://repo1.maven.org/maven2/com/alphacephei/vosk-android/0.3.47/

it will not help you likely if your problem about M1, I wrote you already
