i imported media pipe and getting this error while building the apk

Will you describe how you imported this plugin? (e.g. how did you download it?)
At the very least, the error message seems to suggest that the issue lies with Niantic Lightship Maps rather than MediaPipe. Would removing this plugin allow the build to succeed?

[HassannKhan]

Imported it every possible way that you can think of. Niantic is main part of my project's functionality so that can not be removed. However I can confirm you this that if you remove niantic it will surely build an apk but that's not what I want sir. I want it to work smoothly with current setup.

[homuler]

I'm asking whether removing this MediaPipe plugin, not Niantic, would allow the build to succeed.
But after all, if removing Niantic allows the build to succeed, wouldn't that mean the issue isn't with this plugin?

[HassannKhan]

The build is successful if either one of them is removed. As I said, niantic can't be removed. Mediapipe needs to be added. Both needs to work at the same time. That's the use case here. Why would I need to remove any one of them?

[HassannKhan]

Anyways, if I tell you what's actually causing the issue. Would you be kind enough to make the changes for me? Or atleast tell me how it can be done? 

[homuler]

Why would I need to remove any one of them?

I am asking questions because it is necessary to identify the cause in order to solve the problem.
If the issue lies with Niantic, I wouldn’t be able to provide an answer even if you ask me.

If it’s possible to build when only one plugin is imported, I suspect that there might be a conflict between libraries.
Judging from the error message, does Niantic’s plugin also include Google.Protobuf.dll?

[HassannKhan]

does Niantic’s plugin also include Google.Protobuf.dll?

Yes, and a version number 3.0.0

[homuler]

If you delete it, can you build your app?

[HassannKhan]

If I delete Media Pipe, I can build the app.

[homuler]

I mean Google.Protobuf.dll (v3.0.0) in Niantic's plugin.

[HassannKhan]

Removing that does nothing. Somehow it still gives the same error.  Yahoo Mail: Search, organise, conquer On Sun, 19 Jan 2025 at 7:33 am, Junrou ***@***.***> wrote: I mean Google.Protobuf.dll (v3.0.0) in Niantic's plugin. — Reply to this email directly, view it on GitHub, or unsubscribe.

[homuler]

It is likely that the issue is caused by a conflict between two plugins, but it seems to be a problem specific to your project, so it's difficult for me to investigate the cause on my end.

Anyways, if I tell you what's actually causing the issue. Would you be kind enough to make the changes for me? Or atleast tell me how it can be done?

If the cause is identified and any modifications are necessary for this project, I believe it would be possible to address them, so please let me know.

@homuler QUICK QUESTION

Will it work if Graphic API of unity is OpenGL ES 3.0 instead of Vulkan ?

[HassannKhan]

@homuler and don't worry about the conflict of protobuf files, I took care of that issue.

[homuler]

Will it work if Graphic API of unity is OpenGL ES 3.0 instead of Vulkan ?

Yes. Actually, the sample app (Android) uses OpenGL ES.

Rather, to avoid copying the input image to the CPU, it is necessary to use OpenGL ES.
Note that some features may not work in version 3.0.

[homuler]

@HassannKhan By the way, has the original issue been resolved?

[HassannKhan]

yeah, I made changes into one file while making sure it doesn't break the functionality.

@homuler If my aim is to achieve background removal. Can this be done using the segmentation masking this provides?

I wrote a shader, but it works only when graphic API Vulkan is selected.

[homuler]

If the issue has been resolved, please write down the cause and the solution if possible and close the issue.
For questions unrelated to the original issue, please create a separate issue to ask them.
