Never use TextReader. Use File.ReadList or File.ReadString.

In your case it looks like a CSV file so you should use StringUtils.LoadCSV.

Hi @Erel

In fact, this night, after much research, on the forum, I found the solution. I loaded the library StringUtils and wrote this code:

B4X:

Dim su As StringUtils
    Dim taggax(10) As String
    Dim descx(10) As String
    Dim tot As Int
    tot=1
    For Each Row() As String In su.LoadCSV (File.DirAssets, "myfile.txt",",")
        descx(tot)=Row(0)
        taggax(tot)=Row(1)
        tot=tot+1
    Next

Whenever I have files in my apps that have key/value pairs (eg: settings files) I always create a map then use File.ReadMap2 & File.WriteMap.

KVS2 is much better than File.WriteMap / ReadMap as a key value store. ReadMap / WriteMap create a text file so they only support simple types.

Yep - I use KVS2 as well, but for simple text files with key/value pairs I use ReadMap & WriteMap - partly because I have a standard settings class that I use in all my apps & I can't be bothered rewriting it!
