How to Build a Simple Note Android App using MVVM and Room Database?

Android provides us a feature with which we can store users’ data inside their mobile itself with different storage options such as Shared Preferences, SQLite database, and the Room Database. All the data storing techniques are having different use cases. In this article, we will specifically take a look at using a Room Database with Architecture Components in Android. In this article, we will be specifically looking at components such as LiveData, ViewModel, and Room. We can get to see the explanation of each component in detail. Below is the guide for it.

The components which we will be using inside the application are listed below with a detailed explanation :

• LiveData: Live Data is a data holder class that can be observed. It holds as well as caches the latest version of the data and notifies our observer whenever the data is being updated or changed. Live Data automatically manages all of this since it is aware of the relevant lifecycle status changes while observing.
• ViewModel: View Modal acts as a communication center between repository and UI. The UI no longer needs to worry about the origin of the data. The ViewModel instances survive Activity/Fragment recreation.
• Repository: Repository is a class that is mainly used to manage multiple sources of data.
• Entity: Entity is an annotated class that is used to describe a database table when we are working with Room.
• Room Database: Room Database is an improvised version of SQLite Database. It simplifies the database work and serves as an access point to the underlying SQLite database. The room uses DAO to issue queries to the SQLite database.
• DAO: DAO is a Data Access Object which is used for mapping SQL queries to functions.

What we are going to build in this article?

We will be building a simple Notes Application in which we will be displaying the list of notes in Recycler View which is added by the user. Along with that, we will be also able to add a new note to your app. We will be using Room Database for storing data in users’ devices. Below is the video in which we will get to see what we are going to build in this article. Note that we are going to implement this project using the Kotlin language.

Step by Step Implementation

Step 1: Create a New Project

To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. Note that select Kotlin as the programming language.

Step 2: Updating build.gradle (project) file.

Navigate to the app > Gradle Scripts > build.gradle(:project) level file and inside this file, we have to add the below code in that file which will be used for our dependencies versions. So we have to add the below block of code in the last of this file.

Step 3: Updating your build.gradle (:app) file

Navigate to the app > build.gradle and inside that, in the first plugins section, we have to add id for one more plugin. Below is the code for all the plugins which are present inside our build.gradle.

Now inside the android section in the same file, we have to add the below block at the last part in the android section. Below is the code for that block.

Now add the below dependencies inside your build.gradle file. We have to simply update the dependencies section with the below one.

After updating your gradle file. Now we have to sync your project and then we have to install all the dependencies inside the application by clicking on the sync now option at the top right corner. After installing all the dependencies inside our application we will now be moving to create an Entity for our application.

Note taking open-source application aimed to have both a simple interface but keeping smart behavior.

The project was inspired by the absence of such applications compatible with old phones and old versions of Android. It aims to provide an attractive look and follow the most recent design guidelines of the Google operating system.

Follow the developments and post your comments and advice on Facebook Community at https://www.facebook.com/OmniNotes

Help to keep translations updated is always welcome, if you want give a hand checkout the translation project on https://translate.omninotes.app.

If you’re willing to help speeding up developments please also opt-in for the Alpha version of the app following continuous delivery principles:

Currently the following functions are implemented:

• Material Design interface *Basic add, modify, archive, trash and delete notes actions
• Share, merge and search notes
• Image, audio and generic file attachments
• Manage your notes using tags and categories
• To-do list
• Sketch-note mode
• Notes shortcut on home screen

Further developments will include:

• Notes sychronization
• Web interface to manage notes (stub project)

You can find a complete changelog inside the application settings menu!

If you need some help on how to use the application you’ll find everything you need in the Help Online section.

Look into the wiki for GIFs-based tutorials: LINK

Watch the following terminal session recording on how to compile distributable files

To be sure that build environment is fully compliant with the project the following command creates a container with all the needed tools to compile the code:

To execute all tests included into the project connect a device or emulator, then run the following command:

To speedup the development more levels of testing are available following the testing pyramid approach, each type test requires more time than the previous one.

Notice that in this case I specified a single flavor to run tests on. This could be a useful and faster approach when you’re testing specific flavor features.

Due to the fact that I’m using gitflow as code versioning methodology, you as developer should always start working on develop branch that contains the most recent changes.

There are many features/improvements that are not on my roadmap but someone else could decide to work on them anyway: hunt for issues tagged as Help Wanted to find them!

Feel free to add yourself to contributors.md file.

New feature or improvements contributions

This kind of contributions must have screenshots or screencast as demonstration of the new additions.

If you plan to manipulate the code then you’ll have to do it by following a specific code style. Also pay attention if you’re using any plugin that automatically formats/cleans/rearrange your code and set it to only change that code that you touched and not the whole files.

Test your code contributions!

All code changes and additions must be tested. See the related section for more informations or this two pull requests comments: one and two

When forking the project you’ll have to modify some files that are strictly dependent from my own development / build / third-party-services environment. Files that need some attention are the following:

• gradle.properties: this is overridden by another file with the same name inside the omniNotes module. You can do the same or leave as it is, any missing property will let the app gracefully fallback on a default behavior.

A public instance of SonarQube is available both to encourage other developers to improve their code contributions (and existing code obviously) and to move the project even further into transparency and openness.

Checkout for it here

Pull requests will be automatically analyzed and rejected if they’ll rise the code technical debt.
