Hi,
This could be done for android by adding this
<data android:mimeType="application/pdf" />
in the intent-filter in AndroidManifest.xml (in android studio).
I searched but couldn’t find anything in react-native or expo for handling incoming pdf file.
How can i catch this file name when opening a pdf from outside the app?
note: just found this feature request which is a bit similar:
Greetings
Hi @flieks, so far we only support app linking via url schemes, where you could pass the file name as a url parameter (ie) https://docs.expo.io/versions/latest/guides/linking.html#in-a-standalone-app . Afaik, intent-filters can only be done right now via detached mode.
We will try our best to implement the requests on our feature board, please add/upvote feature requests if there are some things you wish to see in the future!

Hi @quinlanj 
Is there any update on the integration status of the share receive feature? I would love to use the full fleshed expo experience while still being able to recieve data from other apps and being listed when a file is being shared.
Is there any way to do that now without ejecting?
It seems like quite a few people have requested this for quite some time now:
