The past decade held a lot of movies, some left a mark and some were just a set of 24-60 pictures per second. We would like you to create a Master - Detail Application to showcase those movies and the signature they left behind.

• You will have a local list of movies that should be displayed in any order.
• The list is searchable and the search results will be categorized by Yea
• Each search result category will hold at most the top rated 5 movies of this category (year)
• Once a movie is selected from the search results, you will switch to a detailed view to unveil the following:
• Movie Title
• Movie Year
• Movie Genres (if any)
• Movie Cast (if any)
• A two column list of pictures fetched from flickr that matches the movie title as the search query.

• The movie name, picture and rate should be displayed.
• There shouldn’t be any delay if we have a huge list of movies.
• The movies should be displayed in a grid of two columns.
• A loader should be displayed during loading the movie.

The Movie screen should contains:

• Movie Title
• Movie Year
• Movie Genres (if any)
• Movie Cast (if any)
• A two column list of movie pictures.
• The movie photos should be scrollable until all the photos displayed

• The search result should contain only 5 movies for each year if their title matched the entered text.
• A loader should appear during executing the query
• The prcessing time should be lest than half secound to simulate the real time process.

In the app. Clone and run the repo now :D.

The soltuion to avoid any exceptions that we make heavy consumtion in the database if we inserted them with only one statment or making them one by one is:

• Sort them like the order you will display in the home screen with search algorithm that takes O(nlogn)
• Group the sorted list by year.
• Insert each group one by one with making half second delay betwean each group.

The solution to handle this racing issue is: Listen to the movies tabke until the counter of the raws of the table increase than 0 after that execution the fetching statments.

I belive in Law of inertia, also called Newton’s first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

Every thing in life is state and to move from any state to another there should be an action done to make this transation.

Let's simulate this in our android world :D. Each screen represented as imutable state and to move from any state to another should be an action done by the user or the system like location detected.

That's what the MVI pattern is taking about, but I hated every resprentation for MVI that concatenate each in a single every action in one stream and make many switch cases to diferenate between them even if I know the action before and I can call the specific function in the without making an switches.

So I implemented the MVI with new changes in this example. After that I detected that there an awseome android framework from Airbnb, it's name MvRx (pronounced mavericks).

MvRx built amazing framework with caring about awesome details and introduced awesome ideas using kotlin features. I really loved it and make me very keen on seeing what they are intrduces in other android.

The second thing they introdued they introdued another third party for making the implenation from the simple recyclerview to the monster recylerview be so easy to be implemented.

They make the recyclerview be like you are typing DEVs each one under the other in the HTML and introduces Epoxy.

So I was very very very impresed by those cristal minds and used those two third party libratis in my all projected that made our android world and the framework more easier and happier :).
