Note :
please consider ,I have tried to keep these basic tutorial , simple and without any extra code , and focus on main purpose of video😊
Here we'll learn the basics of Retrofit and create an Android client for HTTP requests.
For fetching and sending data from/to the server, we have a lot of network libraries. Retrofit is a complete replacement of Volley and all other libraries, for example. In terms of performance, ease of use, extensibility, and so on.
In this tutorial, I want to use www.themoviedb.org's API .
For this, you need an API key. Please register and find your key under the Settings, API Section.

Glad to hear it! 😊✨

@vinithanabar277 Год назад

I felt like you have just made the implementation of recycler view complex. And it would have been more good if you would explain about interceptor more. It will be slightly tough for beginners to understand. But still I managed to understand. A little bit of more explanation will make your content more good😊

Hi Professor . First of all, thank you for your good course. The second thing is that I encountered an error and I don't know how to fix it. I even copied your code into Github, but the problem still didn't go away. Thank you for helping me ❤️ Error: 👇 E/RecyclerView : No adapter attached ; skipping layout

@AndroidGeekCo Год назад

Hi Meisam , you're welcome😊 , i have checked the source code on GitHub and works for me without error and i could get the list of movies , so please check again your code with the git repo and also please check your adapter , and also where you passed the list into your adapter then set for Recycler view's adapter 😊 if you have any question , don't hesitate , ask me 😊

@AndroidGeekCo Год назад

Thanks for your feedback 🤩 you can go to the website: www.themoviedb.org/ and register on it and then under setting section you can find your own API KEY and then paste it into your code

@vladyslavdremliuha6147 Год назад

@@AndroidGeekCo Thanks a lot, I've done that. But my application does not start, the loading wheel on a blue background is constantly spinning :-(

@AndroidGeekCo Год назад

so , you should debug your app , in the logcat you can see what code you get when the request sending , or ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KAuifVDU9F4.html here on the onResponse method please put several log , step by step while completing this part and check logcat .

@swastikpanigrahi8398 Год назад

Hi, I am getting this error : no adapter attached ; skipping layout. Could you please help me to resolve this?

@AndroidGeekCo Год назад

Hi , its hard to say , maybe there is something wrong in your adapter or your Recyclerview's xml , Do you have your code on GitHub to check? please check your code with repo code and make sure all the things are same : github.com/ezatpanah/Retrofit-RU-vid

How to fetch specfic data from nested JSON using retrofit in Kotlin?

@AndroidGeekCo Год назад

Hi , there is several way , but basicly , you can create your custom data class with exact model that you want to have it in your app and also you can use Serialize for better managing the name betwen your model and the json side (in addition , it depends on your json , maybe you need to have even more than 3 data class inside one data class to handel it , it depend on your json and the data that you want to fetch! )

@mohamedraafat123 Год назад

Does he use a specific architecture pattern like mvvm or not in this video

@AndroidGeekCo Год назад

in this video , there is no specific architecture pattern like mvvm , the purpose of this video is showing the concept of working with retrofit .in the future we will have a lot videos about ,how we can using architectures in kotlin

@johnhabibpour8375 Год назад

Hi Reyhane, Thanks for your awesome video,yes I am beginner in Android, I did all steps you did but my app just stops in mainActivity and shows white page without any error, Another thing that I didnt understand is about POSTER_BASEURL you didnt mention where is come from ? Thanks

@AndroidGeekCo Год назад

Hi , Thank you for your feedback 😊 and about your issue, in the Mainactivity , we put some response code Log; first please check this log, and then you can see which part of your code doesn't work, here : github.com/ezatpanah/Retrofit-RU-vid/blob/master/app/src/main/java/com/ezatpanah/retrofit_youtube/ui/MainActivity.kt you can check again my code and put your log like that

@AndroidGeekCo Год назад

and about POSTER_BASEURL , developers.themoviedb.org/3/getting-started/images -> here ,you can check documentation of this API 😊

@johnhabibpour8375 Год назад

I really appreciate it for quick response, the error is (2022-09-01 13:01:51.984 21299-21299/com.john.tmdp E/onFailure: Err : 404) Client error response, may I ask you how can I fix it, Actually I downloaded yours and changed with my API key it's working very well, Thanks a lot

@AndroidGeekCo Год назад

404 or Not Found , maybe something wrong with your base url / also check : github.com/ezatpanah/Retrofit-RU-vid/blob/master/app/src/main/java/com/ezatpanah/retrofit_youtube/api/ApiServices.kt with your code , and also your response model class , let me know the result 😊

@johnhabibpour8375 Год назад

I checked them with your code , there is no difference , I confused completely, sorry about bothering

What about MVVM and Coroutines?

@AndroidGeekCo Год назад

As soon as possible 😉 first I need cover basic topic and then I can cover mvp , mvvm , mvi 😊 and about coroutines , sure , I guess next video or after next is about coroutines 😊

@kakakaka9408 Год назад

where do you generate the api key

@AndroidGeekCo Год назад

www.themoviedb.org For getting API KEY , Please register and find your key under the Settings, API Section.

@mohamedelgohary683 Год назад

Why didn't you use Fragment and navigiation

@AndroidGeekCo Год назад

Because the main focus was on retrofit and how we can work with that, for others tutorial, I will use a single activity with Fragment and navigation 👍
