java - Android Unhandled exception: org.json.JSONException with ion -

i'm trying json array ion (https://github.com/koush/ion) error: unhandled exception: org.json.jsonexception :(

my json:

[{"title":"hello world","text":"this text"}] 

my code:

@override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_json);          ion.with(myactivity.this)                 .load(getstring(r.string.json_url))                 .asjsonarray()                 .setcallback(new futurecallback<jsonarray>() {                     @override                     public void oncompleted(exception e, jsonarray result) {                         if (e != null) {                             toast.maketext(myjson.this, "error loading strings", toast.length_long).show();                             return;                         }                         jsonobject c = result.getjsonobject(0);                         if (c.has("title")) title = c.getstring("title");                         if (c.has("text")) text = c.getstring("text");                       }                 });      } 

can tell me did wrong, please? :(

edit:

error:(48, 17) error: method setcallback in interface future<t> cannot applied given types; required: futurecallback<jsonarray> found: <anonymous futurecallback<jsonarray>> reason: actual argument <anonymous futurecallback<jsonarray>> cannot converted futurecallback<jsonarray> method invocation conversion t type-variable: t extends object declared in interface future 

i solved problem guys :)!

i changed: jsonarray (org.json.jsonarray) to: jsonarray (com.google.gson.jsonarray)

and added this:

jsonobject c = result.get(0).getasjsonobject(); 

this code now:

@override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_json);          ion.with(myactivity.this)                 .load(getstring(r.string.json_url))                 .asjsonarray()                 .setcallback(new futurecallback<jsonarray>() {                     @override                     public void oncompleted(exception e, jsonarray result) {                         if (e != null) {                             toast.maketext(myjson.this, "error loading strings", toast.length_long).show();                             return;                         }                         jsonobject c = result.get(0).getasjsonobject();                         if (c.has("title")) title = c.get("title").getasstring();                         if (c.has("text")) text = c.get("text").getasstring();                       }                 });      } 

this solved problem!
