此设置在调试版本中运行良好，但是当我生成发行版本时，这会导致错误

---

This setup is working fine in debug build, but when I generate release build, this causes error

字段Catagory.channeList具有RealmList类型，具有ArrayList

field Catagory.channeList has type RealmList got ArrayList

---

不知道为什么它可以在调试版本中工作. 我已经通过了一些解决方案，但就我而言没有运气. 任何帮助将不胜感激，谢谢

Don't know why its working in debug build. I have gone through some solutions but no luck in my case. Any help would be appreciated, thanks

推荐答案

最终找到了使用的解决方案.

Finally found the solution using.

    gsonBuilder.registerTypeAdapter(new TypeToken<RealmList<ChannelList>>(){}.getType(), new RealmStringDeserializer());

    Gson gson = gsonBuilder.create();
    retrofit = builder.client(httpClient.build()).addConverterFactory(GsonConverterFactory.create(gson)).build();

和

public class RealmStringDeserializer implements JsonDeserializer<RealmList<ChannelList>> {

@Override
public RealmList<ChannelList> deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException {

    RealmList<ChannelList> realmStrings = new RealmList<>();
    JsonArray stringList = json.getAsJsonArray();

    for (JsonElement stringElement : stringList) {
        realmStrings.add(new ChannelList());
    }

    return realmStrings;
}
}
