Both users are running the same app on the same device?

Yes, Manfred.
Do you have any idea about this topics? I search the forum, cannot find a easy way to do this job. Many of them are quite complicated and that is totally out of my abilities.

If both sender and receiver are users of your app.
Why not just saving the file in the internal directory (user A). If user B open the app the app looks into it internal folder and check if there is a file to load.

User A gets a mobil phone. User B gets another mobil phone. They stay in two difference city. I have no idea how to transfer the file. Maybe we should use cloud resources to help to do this job.

By the way, this application will allow thousands of users to transfer their design results (which will be only ten item no). They will share the results through the file transfer.

this is NOT what you answered to my question.

Yes, Manfred.

They stay in two difference city

- Implement push notifications in your app (Firebase FCM). Send a push to device b and as text you put the 10 itemnumbers.
- Upload it to your webserver

You could try using Firebase Storage: FirebaseStorage - Simple file storage backend

Even Dropbox is an alternative.
