Android Question How to send a file from my android to my computer

A quick search lists a few possible solutions ...

A nice and simple way, which is also used by B4A-Bridge, is to embed a FTP server in your app: https://www.b4x.com/android/forum/threads/74320/#content

You can then copy files back and forth using Windows Explorer (as done with Tools - B4A Bridge - Explorer).

This open Windows Explorer with the path to B4A-Bridge ftp server. Very useful.

Thanks for the link !
In fact, I already did many searches and have looked at many threads but never found the right ideas. That's why I finally decided to make a post.
Let me try to be more specific :
- the file I want to send from my Apps will always be the same : no need to browse and select it
- the transfer must be made with lines of code only and without any human interaction
- the file can be sent to :
* a computer, (directly in a specific folder),
* a mail box
* any places which can be access from a computer
- the transfer must not use USB cable
- the transfer must be wireless : bluetooth of wifi (the phone where my Apps is, has no 3G/4G connection,)
- the transfer must be done without any installation of a software on the PC

cordialement !

Thanks Erel (your post appears after mine)
I did not know we could do that.
However, I am looking for something embedded in my Application.

I know. The FTP server is embedded inside your app.

I use:
- SAMBA (folder shared in a PC and one USER WITH PASSPWORD. This need the PC and ANDROID Device are in same netwoork)
- DROPBOX (there are a library for this.)
- FTP or SFTP
