  @Part(         


        

Answer 1

For your issue, please use as the documentation

Scalars (primitives, boxed, and String): com.squareup.retrofit2:converter-scalars

So, add compile 'com.squareup.retrofit2:converter-scalars:2.0.1' into build.gradle file

Then...

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(API_URL_BASE)
    .addConverterFactory(ScalarsConverterFactory.create())
    //.addConverterFactory(GsonConverterFactory.create())
    .build();

Hope it helps!
