Introduction

Stetho is a sophisticated debug bridge for Android applications. When enabled, developers have access to the Chrome Developer Tools feature natively part of the Chrome desktop browser.

In today's tutorial, we are going to learn how we can use sthetho-realm - a Realm module for Stetho to view an encrypted realm database file.

An encrypted realm as the name implies is a realm that is encrypted using a particular key (64byte key)

We develop an Android application that displays a list of Realm Objects and then we use the Sthetho-realm module to view the encrypted realm file stored on the android device.

Overview

• Tutorial Introduction: In this part of the tutorial, an introduction to Stetho and Stetho realm is done.
• Dependencies Used: In this part the used dependencies in the tutorial are being shown here, dependencies such as - butterknife (Used for view injection), Lombok library (Used for reduction of Boilerplate code), Realm(Used for storing realm objects), Realm Adapter(Used to create custom RealmRecyclerViewAdapter) Sthetho,
• Setting up Realm Database and custom RealmRecyclerViewAdapter - In this session of the tutorial, we set up the Realm Database, creating the RealmObject class file (Countries.java), Creating a JSON file from which we will be populating our Realm Database from (countries.json), we then create our RealmRecyclerViewAdapter which is a custom RecyclerViewAdapter.
• Setting up our layout file (activity_main.xml) : This part of the tutorial, we set up the main activity layout file where we add a TextView and then add a RecyclerView element and also create the sample layout file for each RecyclerView objects.
• Linking Everything Together - In this part, we link all the earlier created components of the Application which includes creating an Application class file where we initialize our Realm for the application, set up our Stetho object indicating the encryption key and also the name of the encrypted Realm file, creating the Realm Objects from the JSON file, Initializing the RecyclerView and it's adapter.
• Viewing Encrypted Realm file using Sthetho in Google Chrome Browser - Finally here, we used the Google Chrome Dev tools to view the content of our encrypted realm file.
