I was integrating Api ( Webservice) in android app I came across following error.

com.google.gson.stream.MalformedJsonException: JSON forbids NaN and infinities: NaN at line 1 column 123 path

I was using Retrofit with GsonConverter. Section 2.4 of JSON specification disallows special double values (NaN, Infinity, -Infinity).

so how to solve this problem?

we can use Following GsonBuilder properties


your final Retrofit client should look like this

public static Retrofit getClient() {

Gson gson =
new GsonBuilder()

String baseurl = BuildConfig.BASE_URL;

retrofit = new Retrofit.Builder()

return retrofit;

Hope it helps.
