search does not show keyboard

[adhicl]

Hi, I have been trying to automatically do search when user enter screen. I am using react-navigation with its stack navigation and I set isSearchActive value in toolbar to true and autofocus to searchable that show the search bar and the search text input is focused on (the cursor is there)
But the problem is the android keyboard does not automatically show up. I need to tap on the search bar to show the keyboard. Do you have any solution?
