Members description:

DecodeBase64 (Data As String) As Byte()

Decodes data from Base64 notation.

DecodeUrl (Url As String, CharSet As String) As String

Decodes an application/x-www-form-urlencoded string.

EncodeBase64 (Data() As Byte) As String

Encodes the given bytes array into Base64 notation.
Example:
Dim su As StringUtils
Dim encoded As String
encoded = su.EncodeBase64(data) 'data is a bytes array

EncodeUrl (Url As String, CharSet As String) As String

Encodes a string into application/x-www-form-urlencoded format.
Url - String to encode.
CharSet - The character encoding name.
Example:
Dim su As StringUtils
Dim url, encodedUrl As String
encodedUrl = su.EncodeUrl(url, "UTF8")

LoadCSV (Dir As String, FileName As String, SeparatorChar As Char) As List

Loads a CSV file and stores it in a list of string arrays.
Dir - CSV file folder.
FileName - CSV file name.
SeparatorChar - The character used to separate fields.
Example:
Dim su As StringUtils
Dim Table As List
Table = su.LoadCSV(File.DirAssets, "1.csv", ",")

LoadCSV2 (Dir As String, FileName As String, SeparatorChar As Char, Headers As List) As List

Similar to LoadCSV. Will load the first row to the headers list.

MeasureMultilineTextHeight (TextView As android.widget.TextView, Text As CharSequence) As Int

Returns the required height in order to show the given text in a label.
This can be used to show dynamic text in a label.
Note that the label must first be added to its parent and only then its height can be set.
Example:
Dim Label1 As Label
Label1.Initialize("")
Label1.Text = "this is a long sentence, and we need to " _
& "know the height required in order To show it completely."
Label1.TextSize = 20
Activity.AddView(Label1, 10dip, 10dip, 200dip, 30dip)
Dim su As StringUtils
Label1.Height = su.MeasureMultilineTextHeight(Label1, Label1.Text)

SaveCSV (Dir As String, FileName As String, SeparatorChar As Char, Table As List)

Saves the table as a CSV file.
Dir - Output file folder.
FileName - Output file name.
SeparatorChar - Separator character. The character that separates fields.
Table - A List with arrays of strings as items. Each array represents a row. All arrays should be of the same length.
Example:
Dim su As StringUtils
su.SaveCSV(File.DirRootExternal, "1.csv", ",", table)

SaveCSV2 (Dir As String, FileName As String, SeparatorChar As Char, Table As List, Headers As List)

Similar to SaveCSV. Will save the headers list as the first row. This should be a list (or array) of strings.
