It looks like a network connection issue with the proxy:

Setting the GOPROXY env var should fix:

This normally means a stale cache:

Try cleaning everything and trying again.

[xfengw]

The same code, compiled successfully on my other computer, I don't know why this happens.

[lucor]

It is difficult to debug with these info. Could you please provide a minimal example that reproduces the problem? Additionally are you by any chance using a third party lib ? If so, please double check if that lib is compatible with android.

[andydotxyz]

Are you certain that you cleaned all caches after compiling for a different architecture? It is worth checking

[andydotxyz]

I think he pasted the code above

[lucor]

It was my understanding that the code provided above was working correctly, hence my question. @xfengw could you please confirm and in case share the code along with the steps to reproduce the issue ?

[andydotxyz]

Oh. My reading of it was that the pasted code worked on Windows but not Android. Hopefully @xfengw can clarify

[✗] could not package the Fyne app: could not package the Fyne app: exit status 1

Things I've done:

• [x] Blown away ~/.cache/fyne-cross/
• [x] Blown away fyne-cross in the build/project directory
• [x] Built the project with fyne-cross for under native Linux amd64
• [x] Read this issue and some other issues in attempt to find a solution. (None found, as of yet, I hope)

Things I'm doing:

• [x] Building a good simple example for comparison (It appears all my attempts do not succeed in reproducing my possible error, I was thinking it was the storage in fyne but nope, or maybe apptabs but nope, so not sure what causing it, My test code https://github.com/Beanzilla/fyne_breaker_53)

[andydotxyz]

You should not need to include fyne/mobile in a Fyne app, it will be included for you. The error is due to you having multiple libraries add the same code, so either you have fyne.io/fyne plus the mobile project, or you are mixing fyne.io/fyne and fyne.io/fyne/v2.

[andydotxyz]

I think that the original error was resolved above, and indeed the new question answered as well. Closing before we get more questions on the same ticket ;).

[Beanzilla]

Ok, Thank you for the help.

That would explain why the example works just fine, because I don't mix fyne and fyne/v2.

Just confirmed yup, I had fyne.io/fyne/dialog while everything else was using fyne/v2/<something>, (simple fix fyne.io/fyne/v2/dialog and we successfully built)
