OctoDroid does not appear in the list of share targets
When sharing an issue URL from the official Github app to compatible applications via implicit intents, OctoDroid does not appear in the list of share targets.
Agreed. Even from a website octodroid does not show
Try Settings app -> apps -> OctoDroid -> Open by default -> Add link -> Tick (at least) github.com. Does that help? (In recent Android versions one needs to own the domain in question to have this ticked by default. Thanks Google.)
As for the web browser, e.g. Chrome doesn't do intent resolving for HTTP targets, so OctoDroid has no chance of being involved there.
Cromite, Fennec & Webview as well? App wise it works
Own the domain. Seriously!! What nonsense..
Yes (precisely, one needs to host a special file pointing to the app and its signature on the domain's web server). Here is the relevant part of the developer docs.
Maybe I could/should add the shortcut to that 'open by default' page to OctoDroid's settings though.
