Retrofit: Retrofit 2 conflicts with ActiveAndroid ORM on Marshmallow

[zeeshanaslam78]

I am using Retrofit 2 with ActiveAndroid ORM

This is Retrofit library that I am using _compile 'com.squareup.retrofit2:retrofit:2.0.0'_

Here is my POJO

`@Table(name = "Authentication")
public class Auth extends com.activeandroid.Model {

@Column(name = "token_type")
@SerializedName("token_type")
@Expose
private String tokenType;

@Column(name = "access_token")
@SerializedName("access_token")
@Expose
private String accessToken;

@Column(name = "expires_in")
@SerializedName("expires_in")
@Expose
private Integer expiresIn;
}`

This error comes up on Marshmallow below Marshmallow its working fine.

If I do not extend Auth class to Model class of ActiveAndroid It workd fine on Marshmallow but I want to use ActiveAndroid as well

Can you please tell what should I do?

[JakeWharton]

This is a problem with Gson being unable to create instances of your Auth type, probably due to some fields on the base class. You need to consult the ActiveAndroid people for this as its their type which is causing the problem when used with Gson.

Your words help me. Thanks!
I found solution. I just need to add this excludeFieldsWithoutExposeAnnotation()

[henrychao24]

@zeeshanaslam78 I have the problem,too.
How do you resolve it?
excludeFieldsWithoutExposeAnnotation,i don't exactly know how to use?

[zeeshanaslam78]

@HenryBrightChao Hope this sample code will help you

Retrofit retrofit = new Retrofit.Builder() .baseUrl(Constants.BASE_URL) .client(getClient()) .addConverterFactory(GsonConverterFactory.create(new GsonBuilder() .excludeFieldsWithoutExposeAnnotation() .create())) .build();

[henrychao24]

@zeeshanaslam78
well done.Thanks.

[TimAimee]

@HenryBrightChao 您好，我想请教下关于retrofit跟activeAndroid冲突的问题，怎么联系您。

[henrychao24]

@TimAimee 你好,我的qq 3214749428. ActiveAndroid早就不维护了,我这边尝试了一下,就换成了 GreenDao,效率提高了不少.
