JSON Object starts with curly brackets and Ends with the Same, It holds the Single Object item.


JSON Array

Where JSON Array starts and ends with Square Brackets and it can hold multiple sets of JSON Objects.

JSON Object Along with JSON Array

As you can see above, We have got our result in JSON Format. (P.S: I’m JSON Handler Chrome Extension to display JSON in Colorful).

Parsing JSON in Android – Android JSON parsing

Creating New Android Studio Project and Choosing Activity

Fire up the Android Studio and Create a New Project and Use name as your choice and Choose Target SDK as your Choice, We are going to Implement Everything on our Own so, Choose EmptyActivity.

My Project Name : JSON Example

My Package Name :

Crafting the UI (User Interface)

I’m changing the Activity Layout to Relative Layout, You can Copy paste the Below Code.

Now it’s time to Fetch the Data from the Server.

Fetching the JSON Data from Server

This is the Core part of our Project. Here We are running the App in Outside of our HOST Machines. So we can’t access it by Localhost.

We Need IP Address to Run our Application.

If you’re using Online Server. You can use Domain Name too.

We Need IP Address to get JSON Data from the Server.

Finding IP Address of the Host Machine.

Finding IP Address in Linux

Open Terminal and Type ifconfig then Press Enter.

Here is my Localhost IP Address. You can check the Below Image.
