See this example: https://www.b4x.com/android/forum/threads/class-fileprovider-share-files.97865/#content
The mime type should be: application/vnd.ms-excel

thanks Erel
I use this code: it works well, but it does not open the file in the program

Dim ii As Intent
        ii.Initialize(ii.ACTION_VIEW, File.Combine(File.DirRootExternal, "aa.xlsx"))
        ii.SetType("application/vnd.ms-excel")
  
        StartActivity(ii

The code opens the program I choose without opening the file in this program

Whenever you see code with File.DirRootExternal you can immediately know that it is broken.

When I open a file xlsx From the file manager, everything is fine and when using the code above it opens the program without the file، The following pictures show what happens when I open the file by my code.

Or what is the correct place to save and open this file?
