Is there a reason for running the workflow on every push?

Is there a reason for running the workflow on every push?

It's already there since I made the workflow to attach artifacts, perhaps I need to restrict on certain path?

[Rian8337]

Apologies, I meant to ask about the artifact part.

[cattokomo]

If you meant why is it need to be attach with APK artifact, see the issue I referenced.

[Rian8337]

I understand why, but I don't understand why the APK artifact must be attached on every push or pull request.

[cattokomo]

There's no reason to it, other than being faster way to build the APK and test it right in your phone whether. I can restrict it to only attach when pushing/making PR on specific path, or restrict it at all and only attach if it's triggered by workflow_dispatch event.

[Rian8337]

or restrict it at all and only attach if it's triggered by workflow_dispatch event.

I think that would suffice. There may be cases where a commit should not be tested publicly (i.e., incomplete implementation of a feature), so it should be opt-in.

[cattokomo]

Then disabling it via commit message could work, such as noci or skipci at the end of commit message.

[Rian8337]

so it should be opt-in.
