Open a document with another app

Hi everyone,

I’m trying to create an app where I create a .csv file and I would open the created file with another installed app that can read it, like Google Sheets for example.

I create the file ok, but I have no idea on how to ask my app to open the file with another app (like when I try to read a file attached to an e-mail for example)

Can anyone help me with this ?

Thanks a lot !

Nicolas
