Best Android Studio Tutorial: How to Parse JSON from URL

Android Json Parsing Tutorial: How to Parse JSON from URL (Android Studio): In this video, I will teach how to do JSON Arrray Parsing in Android from URL of a website. Did you know there was no easy way to parse JSON from a URL into objects in Android? Originally we used JSONArray class to parse. Later Google released another lib called GSON. It was fairly useful and easy but you still needed to do a lot of code yourself, which consumed a lot of your time. Even worse, you needed to do the same thing over and over again from one project to another.

Please note that this tutorial may work on your older Samsung Galaxy, LG, Oppo, Huawei, Sony or Nokia Android phones which run Android Operating Systems depended on their API version.

To use that, first you add a model class that has its properties matching to JSON objects. For example, you have a tbl_post table and 4 attributes (post_id, post_title, post_text, image_url). Then by using json_encode() method in PHP, you should get the same object names in JSON. So, in Android you should create class named Post with 4 properties as well. See the sample code below:

public class Post {
@SerializedName("post_id ")
public int post_id;
@SerializedName("post_title")
public String post_title;
@SerializedName("post_text")
public String post_text;
@SerializedName("image_url")
public String image_url;
}

The SerializeName annotation is the keyword that helps your JSON objects properties match an Android objects properties. You have to make sure they are the same.

Finally, what you have to do is to call a one magic line of code:

JsonConverter

This code will parse the JSON text into objects. You can use that ArrayList for your custom ArrayAdapter to display texts and images in a ListView. But in this video, I make it simpler by just using a text list instead. Stay tuned for another awesome video about the custom ArrayAdapter.

[dotafreecoin]

That great videos, but what if we want to POST data from Android to server with parameter, header, or body. How to do it? Thank before hand for your response.

[goldendraco]

Thank you for the tutorial. Just want to ask, how do I pass the values to a text view instead of a list view.

It would be possible to use two "GetResponseAsyncTasks" in a script?
One to pick up the user data, and the other to pick up the posts?
I tried to use it, but when I put the two he does not think anything.
When I use only the first, it works taking regular user data. I tried to separate in other class, but without success.
I'm using Navigation Drawer.

thanks for this worderful tuitorial!! can you have a crud operation using this?

[marzgaming]

If I had an activity, that gets the JSON Response from the PHP file, how do I put it in a bundle and pass it to some fragments? I think I can't use intent in passing Activity to Fragments.

[sacyac]

How do you display it in a textview?
BTW. Your videos are Awesome !!!

Thanks about this Tutorial. I've learned a lot. I just wanna ask.
I have an android app that should access 1 of 3 tables(3 types of users), and I wanted to pass the usertype and username to a php file, and retrieves the details of that username(assuming it's already logged in) from 1 of the 3 tables to a json array.
What should be the correct format for the URL to post/get the json array?

I apologize if I'm giving you a hard time.

UPDATE:

I already solved it, but I had to customize the link on task.execute(); for it to perform $_GET instead of $_POST. Again, thanks for this tutorial. :)
