Select a Basic Activity template for it and on the last window of the project creation wizard, change the Activity Name to TaskListActivity. You can use an IDE of your choice, but the tutorial will give instructions specific to Android Studio. To get started, first create an Android project (I named mine Tasky). We'll create a To Do application which will enable the user to create, edit and delete tasks from a list. We are going to see how to integrate it into an Android app and perform the usual CRUD operations on it. In this article though, we are going to focus on the Realm Mobile Database. If your application needs to store user data to the cloud and have it synced on all devices used by the user, you can use the Realm Mobile Database together with the Realm Object Server for this.
If one thread or process modifies an object, other threads and processes can be immediately notified. You don’t have to copy objects out of the database, modify them, and save them back-you’re always working with the “live,” real object. Unlike a traditional database, objects in Realm are native objects. On performance, Realm is said to be faster and it also offers other modern features such as encryption, JSON support and data change notifications. To perform the same operation in Realm, you usually end up writing fewer lines of code than you would with SQLite or Core Data. Compared to these two options, Realm is easier to set up and use. The Realm Mobile Database is a cross-platform database solution that can be used as an alternative to SQLite and Core Data.
