This project is simple Android Note App to learn recommended by Google MVVM and Repository Pattern.

Try to use these technology Coroutines, Room , Navigation Component, unit test with io mockk, koin etc. without remote service.

While doing this app, I want to explain my tech stack in android development process.

• Firstly, This app created with MVVM (Model-View-ViewModel) that is recommended by Google and written on Kotlin Language 100%.
• While using MVVM, I chose Single Activity-Multiple Fragments Structure with JetPack Navigation Architecture Component
• On the other hand we know that if the app is not big enough as we can use Single Activity-Multiple Fragment structure otherwise it can not be good performance such as CPU, Memory Allocation and Memory Leaks etc.
• Besides that, I used Light weight koin Dependency Injection Library works as Service Locater that provides SOLID principles and doing maintainable test easily.
• While doing database operation, I used Coroutines to handle. It can easily lifecycle aware and lightweight thread system to deal with Input Output operations with IO Thread. Thus Main thread may not overload.
• For the UI, the Material Library used in this project as possible and use some Animations and Transitions.
• For the local data provider, I used Room SQLite DataBase and SharedPreferences.
• Business Operation are in the following; Users can edit, delete and create their notes. There are two tables one - to - many relationships each other that are NoteModel(represents Many) and UserModel (represents One)
• For the Helper to User Operations, I Used Shared Preferences Manager while create, edit and delete operations and to handle Users.
• Unit tests were written for repository and view model
• Trying to use Kotlin Lint and Android name conventions.

Project is included according to user create a notes, update their notes and delete their notes if note updated note changed.
