This was originally suggested feature by users on both Android and iOS in the reading list usage survey (T164770).
=== User story
As a user who accesses Wikipedia through my browser as well as the app, I want to be able to add articles accessed through the web directly to my 'Saved' list in the Wikipedia app.
=== Proposed solution
Add "Save to reading list" as a [[ https://developer.android.com/training/sharing/shareaction.html | share action ]] from the user's device browser (on devices where the app is installed).
- The new "Save to reading list action" is only available on wikipedia domains
- The action saves to the default list, and shows a toast.
- The current share action of 'Search Wikipedia' should remain in place
Note: For the Desktop web browser extensions, see task T191221.
Equivalent task in the iOS app T145876
