Retrofit2.0

# Retrofit 2.0 Notes

### Dependency
```
compile 'com.squareup.retrofit2:retrofit:2.0.2'
compile 'com.squareup.retrofit2:converter-gson:2.0.0'
```

### Create service generator
```
public class ServiceGenerator {
    private static OkHttpClient.Builder httpClient = new OkHttpClient.Builder();

    private static Retrofit.Builder builder =
            new Retrofit.Builder()
                    .baseUrl(BuildConfig.HOST)
                    .addConverterFactory(GsonConverterFactory.create());

    public static <S> S createService(Class<S> serviceClass) {
        Retrofit retrofit = builder.client(httpClient.build()).build();
        return retrofit.create(serviceClass);
    }
}
```

### Create Model
```
public class Person {
    @SerializedName("id")
    public int id;
    @SerializedName("name")
    public String name;
}
```

### Create interface for API services
```
public interface ApiService {
    @GET("/path")
    Call<List<Person>> getPersonList();
}
```

### Using the API service
```
apiService = ServiceGenerator.createService(ApiService.class);
Call<List<Person>> call = apiService.getPersonList();
        call.enqueue(new Callback<List<Person>>() {
            @Override
            public void onResponse(Call<List<Person>> call, Response<List<Person>> response) {
                if (response.isSuccessful()) {
                    // tasks available
                } else {
                    // error response, no access to resource?
                }
            }

            @Override
            public void onFailure(Call<List<Person>> call, Throwable t) {
                // something went completely south (like no internet connection)
                Log.d("Error", t.getMessage());
            }
        });
```
