    }

I have also added a screen shot of message that i am getting on api call. Everything is working fine is debug build. I am facing issue in release build only. I have already used serializedName for my model. Tried so many answer from stackoverflow from last two days. If anyone have any idea please let me know.enter image description here

Solution

  • Look into your mapping file what f.i.d.b.c.c.a refers to, if it refers to Model/Pojo then you have to handle proguard rules for GSON or you can add @Keep on top of model class as well.
