audio call recorder for skype

I’ve been battling with this issue for a long time, and at this time have to use a heavy laptop instead of a small light tablet. I need an app that would record audio calls from skype on android tablet. There are some such apps for phones, but for android tablets exist none. In windows for example theres a variety of such programs. Could anyone tell me whether it is possible at all to develop such an app and if not what obstacles could be there? Any help would be appreciated.

I am also searching about this type of app…
