How to call android keyboard to input the text?

Hello, everyone:
I am new to katalon. Now I need to type texts in the text field.
If the text is not number, it should pop up an alert.
I try sendKey or setText method to type letters which should have alert, but it seems like it can not trigger that alert.
Only when I call the keyboard and type the key in it, it will pop up the alert.

My question is since under test mode, it use appium android input manager, the keyboard will not display. In this case, how can I open the keyboard in the device system and input the thing I want?

Hi @mxu,

To force the keyboard to open, you might be able to use Mobile.tap() to tap on the input field first.

Hope this helps,
