i stumbled across setError() the other day. i don't know that i've ever seen it in the wild, perhaps with reason as its interface is a little 1990's webpage styling. but here it is.
per google documentation:
...Sets the right-hand compound drawable of the TextView (google-ese for our label view) to the "error" icon and sets an error message that will be displayed in a popup when the TextView has focus. The icon and error message will be reset to null when any key events cause changes to the TextView's text. If the error is null, the error message and icon will be cleared. our edittext is a child of android's textview, so it inherits the setError() method. you display the text you want. you can also put up your own icon. when you start to correct your error, the pop-up is cleared.

B4X:
Sub button1_click
If Not(edittext1.Text.ToUpperCase.CompareTo("B4X") = 0) Then
Dim editerror As JavaObject = edittext1
editerror.RunMethod("setError",Array("Bad platform! Erel has been notified."))
End If
End Sub
