Before you can begin to interact with the Realm APIs you first need to initialize Realm. In this video, learn how to get set up.
- Before creating our realm instance,…let's add the Realm dependencies…to our application.…First, we're going to add the Realm plug-in…to the class pad, in our main build.gradle file.…So, let's go ahead and open up…our main build.gradle file,…and right here, on line nine,…underneath where we have our Android gradle plug-in,…we're going to add a new entry:…classpath…and then we're going to type:…'io.realm:realm-gradle-plugin:3.0.0'…and then we can hit an enter at the end of that line.…
The next thing we want to do,…is apply the plug-in to our applications build.gradle file.…So, let's open that one up next,…this is the apps build.gradle file,…and then right underneath where have the Android application…plug-in, here on line two, we're going to type:…apply plugin:…and then, 'realm-android'…Android Studio is letting us know that we need to sync,…so let's go ahead and do that now,…by clicking on the Sync Now link.…
And once that's complete,…we'll have access to the needed Realm classes.…This means we can now configure our Realm instance.…
To begin, Annyce Davis reviews using the de facto data persistence solution available on Android: SQLite. She takes you through basic SQLite concepts—such as how to create a database wrapper and insert data into a table—as well as a few more advanced topics. Next, she covers working with Cupboard, an open-source project dedicated to simplifying your SQLite interactions. To wrap up, she dives into working with Realm, an object database solution designed with mobile devices in mind. Throughout the course, Annyce discusses establishing relationships between database tables, creating and running queries, as well as performing data migrations.
