Can I package this app for F-Droid?

[csukuangfj]

Yes, as long as you describe that it is from
https://github.com/k2-fsa/sherpa-ncnn

[linsui]

Yes, of course.

[linsui]

I have a try https://gitlab.com/linsui/fdroiddata/-/commit/abafba0871a354334e18d28cc649920f09b326dc. But the apk doesn't work for me. I can only see a black screen and it quits after a while. The apk can be downloaded from https://gitlab.com/linsui/fdroiddata/-/jobs/4728967690/artifacts/file/tmp/com.k2fsa.sherpa.ncnn_1.apk.

Can you get the logcat log?

Both of them only show a black screen on my phone. Maybe it just take a very long time to load the model?

[csukuangfj]

Are there more error logs?

[danpovey]

It seems that SEGV_ACCERR could be a permissions related issue. E.g. a different user might own that file versus the user which is running the process? Or wrong permissions? [Edit: seems it can also be stack overflow, but IDK why the stack might overflow.]

It should not take a long time to load the model.

It looks to me that you don't specify the model path correctly or there are some issues with your model, e.g., not updated.
The error is likely from the following nullptr:

sherpa-ncnn/sherpa-ncnn/csrc/model.cc

Line 240 in 655a99b

return nullptr;

Could you first test your model with ./build/bin/sherpa-ncnn and see if it works well?

[linsui]

You apk doesn't work for me either. My build works on another device. So looks like the problem is that this app doesn't work on my phone. I opened #239 for this problem.

[linsui]

Can I add some fastlane metadata for descriptions for F-Droid? I can open an PR. The version name and version code is not updated. Should I patch it, e.g., 2.0.2(20002) or you can set it to a meaningful value? If the version code is always 1 F-Droid can't update the app.

[linsui]

Should I also package the GPU version? It's reported that the perfomance of GPU version on Android is terrible but maybe someone want to have a try anyway.
