Are you looking for a simple and structured database solution for your Android application? Look no further than Android-NoSql! This lightweight NoSQL database allows you to save, retrieve, and manage your data in a user-friendly manner. In this article, we’ll walk through how to implement Android-NoSql in your app, using some simple examples for clarity.

Getting Started with Android-NoSql

First things first, let’s get Android-NoSql integrated into your project. Follow these steps:

• Open your build.gradle file.
• Add the following dependency:

implementation 'com.github.florent37:android-nosql:1.0.0'

• Sync your project to download the library.

Saving Data as a Structured Tree

Imagine your data as a family tree. Just like family members are organized into branches, Android-NoSql organizes data into a structured tree format. Here’s how you can save users in your database:

noSql.put(users, florent);
noSql.put(users, kevin);
noSql.put(identifiers, florent, 10);
noSql.put(identifiers, kevin, 12);

In this structure, your data would look like:

• users
• florent
• kevin
• identifiers
• florent
• 10
• kevin
• 12

Searching Data Made Easy

Finding information in Android-NoSql is as simple as locating a specific branch on that family tree:

int myId = noSql.get(identifiers, florent).integer();

Serialization of Objects

To add a user with details like a house and cars, you can serialize your Object. Think of this as packaging a birthday gift:

final User user = new User(
                flo,
                new House(paris),
                Arrays.asList(new Car(chevrolet camaro), new Car(ford gt))
);

When added to the database, it gets organized like so:

• users
• florent
• name
• flo
• house
• address
• paris
• cars
• 0
• model
• chevrolet camaro
• 1
• model
• ford gt

Fetching Objects

To retrieve user details, you can fetch them easily using:

User user = noSql.get(user, florent, User.class);

Listening for Node Updates

Engage your application to automatically stay up to date! You can listen for changes like they are notifications from relatives in your family tree:

noSql.notify(user, new Listener() {
    @Override
    public void nodeChanged(String path, NoSql.Value value) {
        // notified when :
        // the node is created
        // the node is deleted
        // a subnode is added or updated
    }
});

Initialization

To start using Android-NoSql, you need to initialize it in your main application class:

public class MainApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        AndroidNoSql.initWithDefault(this);
    }
}

Troubleshooting Tips

If you encounter issues while implementing Android-NoSql, here are some common troubleshooting tips:

• Ensure that you have the correct dependencies installed.
• Check your application’s context in the initialization method.
• Make sure your data retrieval methods match the data structure.
• Always look for typos since it can lead to data access errors.
