Android Question Toastmessage followed by long do while loop

[joop]

This is the code :

Sub Load_wordsarray_with_wordsfile

Dim TextReader1 As TextReader
Dim line As String
Dim i As Int
Dim words_array (300000)

ToastMessageShow("Loading file ", True)
TextReader1.Initialize(File.OpenInput(File.DirAssets, "file.txt"))

line = TextReader1.ReadLine
        Do While line <> Null
          words_array(i)= line
          line = TextReader1.ReadLine
          i=i+1
        Loop

TextReader1.Close

End Sub

It takes about 4 seconds to load the file ,and what happens is that
the message "Loading file" is displayed after the array is loaded.

Is it possible to display the "Loading file" before the array is loaded.

Take a look at ProgressDialogShow

Note that you can use File.ReadList to read the file. What is the size of this file?

It is worth checking whether it is faster to read it with File.ReadList.

Your best option is to use a SQL database instead of this file.

You will need to add DoEvents to this loop if you want to show anything:

 Do While line <> Null
          words_array(i)= line
          line = TextReader1.ReadLine
          i=i+1
         if i mod 1000 = 0 Then DoEvents
        Loop
