What is it?

• Bugfix (user facing)
• This PR is for the dev branch.

Description of the changes in the PR

This PR fixes the issue where the default media player preference for downloaded files could not be saved on modern Android versions.

Fixes the following issue(s)

Fixes #13043

Relies on the following changes

The root cause was the usage of Intent.createChooser(), which intentionally prevents the system from showing the "Always/Just Once" options and ignores existing defaults. By passing the viewIntent directly to ShareUtils.openIntentInApp(), the standard system resolver is restored, allowing users to set and persist their preferred media player.

APK testing

The APK can be found by going to the "Checks" tab below the title. On the left pane, click on "CI", scroll down to "artifacts" and click "app" to download the zip file which contains the debug APK of this PR. You can find more info and a video demonstration on this wiki page.
