This branch (master) is being used to study, some branches (android_basics, android_intermediate) were used to teach some students at the university - UFRPE, now they are gone!
Now this repo is being used as a free source to study and develop an application with new Android Features. New Feature that should be merged on master - New Hero Detail Screen
Files that was ignored, should be recreated on the local project of each one. To build the app, go to Marvel Developer and get the keys for you, then you need to copy and paste the credentials.properties.sample and paste as credentials.properties with your credentials.
