com.google.gson.JsonSyntaxException mit GSON

Question

Ich analysiere die Antwort meines Servers mit GSON. Aber immer

com.google.gson.JsonSyntaxException

Derzeit i hartcodierte JSON sende. Alle Booleschen Werte, Float-Werte usw. wurden entfernt. Momentan analysiere ich nur String-Werte.

LoginPOJO.java

package com.chsoneresidential.chsone.pojo; 

import com.google.gson.annotations.SerializedName;
