Android Question error with File.GetText

jt2010 · Aug 7, 2018

Hi. Can you help me with this code:

Sub sample
Dim read,read1 As String
read=File.GetText(File.DirAssets,"cfg.txt")
Msgbox(read,"Testing")' value is file.txt and is ok
read1=File.GetText(File.DirAssets,read)
' Error
' java.io.FileNotFoundException: /data/user/0/direction.slide.id/files/virtual_assets/file.txt: open failed: ENOENT (No such file or directory)
End Sub

I cannot use a variable to use with File.GetText and load a file, but if i use a predefined value (ex: "cfg.txt") it works….any suggestion?
thanks,
Jose

Log(File.ReadString(File.DirAssets,File.ReadString(File.DirAssets,"cfg.txt")))

This is how your code should be:

B4X:

Dim read As String
    Dim read1 As String="newdbfiledate.txt"
    read=File.GetText(File.DirAssets,read1)
    Log("first time: " & read)  'displays the content of file
   
    read=File.GetText(File.DirAssets,"newdbfiledate.txt")
    Log("second time: " & read)   'displays the same content of file as above

hi guys. thanks for the anwsers but the question is how could i use File.GetText to load a text string with a variable value and not a predefined value;

This works:
read=File.GetText(File.DirAssets,"somefile.txt") ' uses a predefined value with comma

this doesn't:
read1=File.GetText(File.DirAssets,read) ' uses a variable

read1=File.GetText(File.DirAssets,read) ' uses a variable

What is the content of read ?
If it's "somefile.txt" it will work !
If it's the result of read=File.GetText(File.DirAssets,"somefile.txt"), it will for sure not work.
Because, in that case, read, is the content of the file and not it's name.
But, unfortunately you don't give enough information.

Klaus, but the variable read1 assumes the string value that was in variable read (somefile.txt) isn't so? it´s the content of file and the filename of the next text file that i want to read;

In another way-..how could i use File.GetFile to do this:
i have two text file that contains only one line with the text:

File1
=========
file1.txt

file2
=========
file2.txt

i want to read the first text file, and put the value stored in a variable (file1.txt);
then use File.GetText to load the content of the file1.txt not with the syntax: File.GetText(File.DirAssets,"somefile.txt") but with File.GetText(File.DirAssets,variablename)

is it possible?
thanks

This will definitely work:

B4X:

  'Added 2 files to assets: file.txt where its content is: content1.txt and a file named content1.txt with its content: this is a test
    Dim read,read1 As String
    read=File.GetText(File.DirAssets,"file1.txt")   'its content is: content1.txt 
    read1=File.GetText(File.DirAssets,read)         'its content is: this is a test
    Log(read)   'displays: content1.txt
    Log(read1)  'displays: this is a test

However, if the content of file1.txt has a variable with a comma, it will not work because you cannot have a file name with a comma in the name. It will return the error you were showing in your first post.

@jt2010
Your code should work.
How did you generate the text files?
Did you encode those with UTF-8?
If you generated the files with Notepad then you might have problems, becaus the encoding is Windows-1252.

Tip: Never use File.GetText. It was added by mistake. Use ReadString instead. Result is the same but ReadString is cross platform.

If you are unable to solve it then please upload a small project that demonstrates the problem.
