 com.google.gson.jsonsyntaxexception: java.lang.illegalstateexception: expected begin_object string @ line 1 column 1 path $ 

big help.

let's @ error receiving.

expected begin_object

your json object, , json objects enclosed in curly braces ({}). begin_object therefore {. , it's expecting somewhere.

but string

but instead found string "something". still doesn't tell where.

at line 1 column 1 path $

ah, perfect. @ line 1 column 1. start of json. have forgotten enclose whole thing in {} (or @ least have forgotten first one, bet you've forgotten them both).
