Developing the dictionary app

With the IDE project, build tool, and required libraries sorted out, we can start developing our app.

Preparing the data

Since the dictionary words are stored in a JSON file, we need to parse the data before saving it to a local database.

First, we'll add the class that will represent our data. In the base package (com.packt.quickstart.dictionary), we first add a new package called data. There, we put the DictionaryEntry class, which will be our data model representation:

data class DictionaryEntry(val term: String, val explanation: String)

The class has two properties: the searchable term and the term definition. It'd be also nice to have a readable string representation of this...
