Method that adds text to a TextArea and scrolls it:

B4X:

Sub lg(msg As String)
   txtLogs.Text = txtLogs.Text & CRLF & msg
   txtLogs.SetSelection(txtLogs.Text.Length, txtLogs.Text.Length)
End Sub

B4X:

txtStatsBox.Text = txtStatsBox.Text & CRLF & ">> Status: Ready." & CRLF  
txtStatsBox.SetSelection(txtStatsBox.Text.Length, txtStatsBox.Text.Length)

This doesn't work for me... Even with Request Focus.
Any solution?

Ummm .. funny Not working for me either

Sub lg(msg As String)
monitor.Text = monitor.Text & CRLF & msg
monitor.SetSelection(monitor.Text.Length, monitor.Text.Length)
End Sub

Do you get to the bottom of this ?

Got it working now. I think it's because I was also writing to the text area from outside this subroutine. Do all text area writes using the subroutine works.

You can also use the scrolltop method with Javaobject https://docs.oracle.com/javase/8/javafx/api/javafx/scene/control/TextArea.html#scrollTopProperty so that way no need to chnage the caret position
