Exploring JSON Deserialization and Parsing in Android Development

Can someone clarify the concept of "deserializing Json" for me? I've come across this term online but am unsure of its meaning. Any explanation would be greatly appreciated.

Answer №1

JSON is a method of representing data in a lightweight text format. For example, an array of contacts in a phone book could be saved like this:

{"contacts": [
{"name": John, "phoneNumber":"+44000000000"},
{"name": Jack, "phoneNumber":"+44000000001"}
]}

Its main use is for transferring data to web services, especially with REST.

Serializing your data to JSON involves converting an 'Array()' in your Java code into a text-based representation as shown above. Deserializing JSON is the reverse process - translating the text back into a data array in your Java application for the contacts mentioned earlier.

Luckily, the Android SDK provides easy access to a JSON library that can handle this process for you. http://developer.android.com/reference/org/json/JSONObject.html

The GSON library further simplifies this process. http://sites.google.com/site/gson/gson-user-guide

There are many examples of using REST with Android available online that can assist you.
