java - Problems in JSON results calling JAWBONE API -


i'm developing android app analyze band data. using example given in sdk android , @ moment can trend data json object. problem json object malformed. in fact when try deserialize trend data with:

jsonelement je = new jsonparser().parse(o.tostring());

i following error:

com.google.gson.jsonsyntaxexception: com.google.gson.stream.malformedjsonexception: expected value @ line ...

moreover, inspecting result of api call get:

the main problem in previous json object keys aren't formed. in fact should strings of characters between "". please give me indication on how solve problem? lot help. [edit]

this callback function starting modify data jawbone:

private callback genericcallbacklistener = new callback<object>() { @override public void success(object o, response response) {     log.e(log_tag,  "api call successful, json output: " + o.tostring()); //i added following 3 lines of code parse json result     jsonelement je = new jsonparser().parse(o.tostring());     jsonobject root = je.getasjsonobject();     jsonelement je2 = root.get("data");     toast.maketext(getapplicationcontext(), je2.tostring(), toast.length_long).show(); }  @override public void failure(retrofiterror retrofiterror) {     log.e(log_tag,  "api call failed, error message: " + retrofiterror.getmessage());     toast.maketext(getapplicationcontext(), retrofiterror.getmessage(), toast.length_long).show(); }

};

ok believe know problem is. using retrofit callback wrong.

you not need parse result. jawbone + retrofit you.

check example:

public interface bookservice{     @get("/books")     void getbooks(callback<list<book>> books); }  // ,  private callback genericcallbacklistener = new callback<list<book>>() {      @override     public void success(list<book> books, response response) {         [...] // use books     }      @override     public void failure(retrofiterror retrofiterror) {      } }  taskservice.getbooks(genericcallbacklistener);

so not try manually parse response. let jawbone android sdk you.
