Got an error com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path – Pranesh Sahu Nov 07 '16 at 13:34
When your Json begins by "{" it s an object one when it begin by "[" it s an array one. As suggest by the others you should verify your structure on a json validator. – Lucas78 Nov 07 '16 at 13:40

There is easy way to do that. Just use POJO generator http://www.jsonschema2pojo.org/ it will give you plain object with necessary annotations. also you can use Json formatter to validate your json https://jsonformatter.curiousconcept.com/ - the JSON you posted is invalid.
