of what you are after?

Are you trying to post links to other sites on DU?
Are you asking how do you use the clipboard copy & paste functions on an Android device?
Are you asking if Chrome Mobile works with DU?

I think you will get your question answered quicker if you can describe what you are trying to do and what doesn't seem to be working for you.

Assuming you mean on DU, I do it the hard way and manually enter the code...you could try viewing the fullsite and using the buttons, Chrome should support that, but it might get annoying on a limited device.

To copy and paste the links, open the target page in Chrome and double-tap the URL to highlight it, then tap the icon of a piece of paper, to the right of the icon with the scissors that will appear above the URL. Go to DU and set up the link code however you'd like, then tap and hold in the text entry area. You should get an icon popup that says "Paste", tap that to paste the URL into the link code.

It's not really difficult per se but it does require a little technical aptitude, if you aren't extremely comfortable using Android it's going to be quite difficult without being shown in person.
