It's afternoon here, clouds and sun are playing hide and seek. I have exams day after tomorrow, have broken various assignment deadlines and now trying to make a console application for google drive using recently released google drive api and sdk. First of all I went to developers.google.com and clicked on Api Console icon, Clicked on create project, and then from the list that came enabled google drive api and sdk. After that went and click API access to create credentials. Drive API uses OAuth2. Create credentials is a step by step process, at first screen add your logo, name of your application. At the second screen when it asks whether you want web application, installed application,etc. Click on Installed application and you will have an option to choose operating system, options are for ios,android and other. Click on other.
