How can I make my app so that if the user copies it installed on his device and sends it to his friends, his friends can't install the app?
I want users to be able to download my app from the market only.
Thanks a lot.
Lock the app to prevent the app from being installed on other people's devices

One of the best ways is to let anyone install app and then enable app features using in-app purchase.
If your application is online, you can submit user IP at sign up and block other IPs from accessing user accounts or better define a count limit for IPs of each account.
I don't think there's any way to prevent app installation on other user phones.
