How to open *.dwg in autocad by default from android gmail client?

Question

gmail

Comrades, good afternoon!
I have a tablet on the latest droid, dwg schemes come to the mail in the gmail application, when I try to open it, it says that the picture is not loaded - you need to teach the gmail client to associate dwg with autocad and open the schemes immediately in it (autocad) by default - plz tell me how this can be do???
