aplikasi saling terhubung melalui jaringan, sehingga kita dapat mengambil dan mengirim data ke layanan tersebut dengan mudah.
Concept 5
What is JSON? 6 (Javascript Object Notation) merupakan format pertukaran
data yang ringan dan mudah dibaca (dibanding XML). Format ini dapat digunakan di hampir semua bahasa pemrograman.

How to read JSON in Android?
3 Ways 14 3 2 Manual Parsing 1 Using GSON
Retrofit + GSON
Let’s start the journey… 15
1. Manual Parsing Change one-by-one 16

Final Code Using LoopJ 19 dicoding.id/cobajson1
Final Code Using Volley 20
2. Parsing With GSON Faster way to convert into model
21
GSON library 22 Buka build.gradle(module: app) dan tambahkan kode berikut:
Data Class 23 Tambahkan annotation sesuai JSON
Using GSON 24
Diff 25
Want more? 26
Nested Class 27 Buat model untuk yang paling atas
Using GSON 28
Diff 29
Source code Gson 30 dicoding.id/cobajson2
3. Retrofit + GSON Converter The best way to convert
all responses 31
Retrofit library 32 Buka build.gradle(module: app) dan tambahkan kode berikut:
Setup Retrofit 33 Endpoint : https://reqres.in/api/users?page=1
Get Data with Retrofit 34 Karena data yang didapat sudah
di-parsing, maka tidak perlu fungsi parseJson lagi
Want more? 35
Service Locator Pattern 36 Supaya tidak mengulang-ulang kode, buat satu
class sebagai kode pusat.
Bonus! 37 Plugin RoboPojoGenerator Otomatis membuat class model dari data
