How this app works

User creates his account via Firebase Password Based Authentication.When a new user is registered the userName is checked from existing userNames and then account is created.User views all the posts on the next activity.The posts are retrieved from Firebase Cloud Firestore, the structure is like this:-

When user creates a post,the image is uploaded at Firebase Cloud Storage ,then it's download URL is saved at imageURL.When user likes a photo the likes value is incremented and username is added in the userName field,if user removes his like then it is removed and subsequently likes value is decremented.The comments are also retrieved from Firebase Cloud Firestore, the structure is like this:-
