Where can I find step-by-step instructions on how to parse a JSON feed in Android? I'm just an Android beginner wanting to learn.
I've coded up a simple example for you and annotated the source. The example shows how to grab live json and parse into a JSONObject for detail extraction:
Once you have your JSONObject refer to the SDK for details on how to extract the data you require.
Android has all the tools you need to parse json built-in. Example follows, no need for GSON or anything like that.
Get your JSON:
now you have your JSON, so what?
Create a JSONObject:
To get a specific string
To get a specific boolean
To get a specific integer
To get a specific long
To get a specific double
To get a specific JSONArray:
To get the items from the array
2.1. Store all these node names in variables: In the contacts json we have items like name, email, address, gender and phone numbers. So first thing is to store all these node names in variables. Open your main activity class and declare store all node names in static variables.
2.2. Use parser class to get JSONObject and looping through each json item. Below i am creating an instance of JSONParser class and using for loop i am looping through each json item and finally storing each json data in variable.
