Description

When download APK android installer from version assets in Gitea on mobile, when click the link from APK we can't juste download and execute to install the app.

Instead, browser want to open it with archive unzipper.

If we download the same APK form nextcloud for exemple, Android try to install it directly...

It's not very usefull when we want to share our mobile app from github versions page...

probably only a matter of mime type response header

[pokapow]

I think so yes, maybe it can be fix by changing mime type in gitea links ?

I got the same issue. When trying to download a .apk file it is downloaded as .zip file.

Gitea version (or commit ref): 1.13.1

[gsantner]

Mime Type should be:
application/vnd.android.package-archive

Are you using an http proxy?

[pokapow]

Yes nginx.

I tried solutions write here: https://stackoverflow.com/questions/46285863/set-headers-for-apk-files-served-by-nginx

But it's doesn't work for me, since Gitea .apk download URL doesn't have the extension inside URL, I think that's the problem.

[gsantner]

I have gitea with apache. If there's a solution and it requires change to webserver config - makes sense to mention it in docs

[zeripath]

So you're trying to download the automatically generated archive files which have filenames *.zip as .apk?

[techknowlogick]

The below is out put from querying the apk from the try.gitea.io link above, seems the content type we are providing is Content-Type: application/zip, I think we are getting the content type from net/http's DetectContentType. A quick/dirty way would be to check if file is determined to be a zip, but has an extension of .apk then we modify the content-type response.
