Learn how to build an Android app with Java that handles JSON data from a REST API service. The app uses the Volley library to create a weather app using API data.
This course includes advice on building a RequestQueue, designing a Singleton, and using callbacks for async network communications. You will also learn to use the Volley library methods JsonArrayRequest and JsonArrayObject to parse a JSON file.

Ive seen many people try and explain android studio projects on youtube. But you got my like & subscribe. You take your time, cut it short on things that aren't important and explain every single step. Great great job!

Thanks so much for this. Was just getting started on learning Volley and you posted it at the right time.

This is fantastic! The fact you go into deep detail into every problem and error and the fact you also visit the documentation is wonderful for someone having first contact with REST APIs in android

@evanhauk 2 года назад

Super helpful! Thanks so much. I used this for a implementation of a different database, and it took the user input and searched for the item in the JSON data and displayed the attributes to a list. Simple but a lot of work to get it working right!

*Wow, im very impressed.* It is my 6. semester in Germany and I searched for help to implement my first own app to get Corona-Data from our institute because I don't want to check every day many of values for different cities. I never thought to found a so damn good tutorial which helps me for all my questions with the API, Callbacks etc. Never saw a video like this. I have no suggestions, it was perfect. My app is working and I have so many ideas for develope it further. It makes a lot of fun. Thanks a lot that I can watch this for free on RU-vid. Greetings from Germany!

@zaidtahir936 Год назад

Do you have a link to that API? bcz I have tried many times but I can't find the API

@TechnikFreakDE Год назад

@@zaidtahir936 Im using an API from a German health institute. It provides only data for Germany, so I think it will not help you.

Dear professor! i really enjoy your amazing tutorial. I learnt a lot and it was an opportunity to create a nice app. thank you very much for putting this tutorial on RU-vid. you are a wonderful teacher!! just one note: this tutorial is definitively not for beginners. it is required to know well classes, interfaces. it is only an advice for other students. but it is a very good introduction to API with android. thank you very much!!

I learnt Basic Java and applied for an internship and the very next day I was assigned to make an application which shows the details of a region form REST API, according to user input and also had to load the previously viewed data even if the user is offline. I've time of 48 hrs only. But now I think I can do it and I'm gonna do it.🔥

@McLovinBillion 2 года назад

I noticed something in the first example of the volley library. When you use the response.substring(0,500) as the response for the stringRequest and the response string is shorter than 500 characters the apps crash because you will get a StringIndexOutOfBoundsException, yeah of course he used just the response as a variable for his Toast but this can lead to some bugs and quickly demotivate especially new programmers.

@ValHustle Год назад

I'm getting the app to crash when using response.toString(); could you please explain why this is happening and how to fix it? Thank you
