Gson (on Android Studio)

Why I met with Gson?

While I was try to store one whole complex object into SharedPerference in Android code, I found that it's default basic data types are not supporting. Also, it's hard to decode them in to json string unless I am writing it's custom encoding function.

Then, I found people are solving this problem using Gson on StackOverflow.
