Proper support for Content URI

hi, i'm reaching out android developer cloudtenna. our users access company files using mobile devices.

 

when viewing pdf cloudtenna, action_view intent content uri started (by cloudtenna android app) , acrobat reader able open pdf correctly.

 

however, seems i'm unable save edits / annotations pdf because acrobat reader saves cached file instead of saving content uri, though flag_grant_write_uri_permission flag has been added content uri, allows receiving app (acrobat reader) write uri without issue.

 

i'm wondering if confirm behavior app, , possibly make changes support opening directly content uris and/or saving content uris. think proper support content uris drastically improve file security when using app making android more work-friendly ecosystem.

looking forward feedback

 

best regards,
