Suddenly I can't build my game on Android Anymore :"Unable to sign the application..

When I build and run, I get the error message “Unable to sign the application, please provide passwords!”. What passwords this error talks about and where I should ‘provide’ them??

Uh-oh my bad. anyone having this issue just go file->build and run, then player settings->publishing settings and create a new keystore password.

The proper way to do it is use the old keystore and put the password in there in the publishing menu. You don’t want to create a new keystore everytime.
