Hi All.
UPDATE: I have a second App with almost identical SetCustomFilter set up but works with GBoard.
I have searched for anything that is different between the two Apps without success. [Designer tick boxes, code, the order of specifying parameters etc.] Obviously it is something in my code I will keep searching but close this question.
Regards Roger
FURTHER UPDATE:
In Activity Create:
DispInput.InputType = DispInput.INPUT_TYPE_NONE 'Prevents pop up keyboard
DispInput.InputType = Bit.Or(0x00080000, 0x00000090) 'NO IDEA WHAT THIS DOES
'DispInput.SingleLine = False
DispInput.Enabled = False
Commenting out the above line solves the GBoard problem.
As an aside, what does the line above do? It sets DispInput.InputType = 524432, but to what effect?
Roger
