Sure, here are the steps on how to integrate Realm in an Android application:

  1. Add the Realm dependency to your project. You can add the dependency to your project's build.gradle file.

Code snippet

dependencies {
    implementation 'io.realm:realm-android:10.10.1'
}
  1. Initialize Realm in your application. You can do this by calling the Realm.init() method in your application's onCreate() method.

Code snippet

public class MyApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        Realm.init(this);
    }
}
  1. Create a Realm instance. You can create a Realm instance by calling the Realm.getDefaultInstance() method.

Code snippet

Realm realm = Realm.getDefaultInstance();
  1. Use Realm to store and retrieve data. You can use Realm to store and retrieve data by creating Realm objects. Realm objects are similar to Java objects, but they are stored in Realm's database.

Here is an example of how to create a Realm object:

Code snippet

public class Person extends RealmObject {

    private String name;
    private int age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}

To store a Realm object, you can call the save() method on the Realm instance.

Code snippet

realm.save(person);

To retrieve a Realm object, you can call the where() method on the Realm instance and pass in a query.

Code snippet

RealmResults<Person> persons = realm.where(Person.class).findAll();
  1. Close the Realm instance. When you are finished using Realm, you should close the Realm instance. This will free up resources and prevent memory leaks.

Code snippet

realm.close();
