Technical details

Previously, the app would intercept all links to f-droid.org, preventing users from browsing the F-Droid website directly. This change modifies the intent-filter in AndroidManifest.xml to be more specific, ensuring that App Lounge only opens links to individual application pages, not the entire domain.

The following changes have been made:

• The intent-filter for f-droid.org now uses a pathPattern that requires the URL to contain /packages/ followed by a valid package name format (e.g., com.example.app).
• The intent-filter for play.google.com now uses a pathPrefix to only handle /store/apps/details links.
• This allows users to browse the F-Droid website and other non-app pages on the Google Play Store without being redirected to App Lounge.

Handling links when both App Lounge and F-Droid are installed

App Lounge, being a system app, has the default handler of these autoVerified links. So, in case where both App Lounge and F-Droid are installed, App Lounge gets the chance to open the link.

However, users can disable this setting by going to Settings > Apps > App Lounge > Open by default and disable the 'Open supported links' switch.

Next, if they want to enable F-Droid to handle this links, the procedure is the same as above with F-Droid's setting and adding handlers using 'Add link' option.

Tests

• On /e/OS Browser, search for "fdroid about".
• Find the result which contains f-droid.org/about. (You can long press the link on the search result to verify)
• Click on the search result.
• Verify that the link opens in the Browser and doesn't navigate you to App Lounge.
• Now Search for a specific app, e.g. "fdroid thunderbird".
• Click on the F-Droid link from search results.
• Verify that the link opens in App Lounge

Follow same procedure to verify Google Play Store apps and links.

Alternatively, you can test this functionality using the following adb commands.
