Gson serialized/deserialized issue when proguard enabled

[GoogleCodeExporter]

When proguard is enabled following json is generated (used gson.toJson(<class 
objectName>)
"{\"a\":\"google\",\"b\":\"19\",\"c\":\"Nexus 5\",\"d\":\"123459056012048\"}"

I am looking for 
"{\"architecture\":\"SGH-I747M\",\"os\":\"samsung\",\"osVersion\":\"16\",\"uniqu
eId\":\"123459056012048\"}"

you will have to keep the original classmembers for this model using custom 
proguard rules.

eg:

-keepclassmembers class com.example.device {
  public *;
}

if your class lookis like this 

package com.example;

public class Device {
  public String architecture;
  public String os;
  public String osVersion;
  public String uniqueId;
}

Thanks but I found solution. I added SerializedName

public class Device {
  @SerializedName("architecture")
public String architecture;

  @SerializedName("os")
  public String os;

  @SerializedName("osVersion")
  public String osVersion;

  @SerializedName("uniqueId")
  public String uniqueId;
}
