Mobile Keyboard

I have an app that captures keystrokes but does not bring up a text input dialog. It works fine for a regular browser, but on a mobile device the mobile “keyboard” does not pop up since there is no input area. Is there a way to force the mobile “keyboard” to pop up?

Thanks!

You need to move focus to the text input, this is the only way to show the keyboard
Text input can be made small and transparent, so end user will not see it

That is helpful, thank you.
