edit:

after removed word "result", able catch error :

07-30 13:32:41.384: w/system.err(16258): org.json.jsonexception: value

[{"path":"http://api.androidhive.info/json/movies/1.jpg","comments":" nice","description":"long story","likes":"5","name":"50 shade of gray"},{"path":"http://api.androidhive.info/json/movies/2jpg","comments":" beautiful","description":"robots","likes":"7","name":"transformers"},{"path":"http://api.androidhive.info/json/movies/3.jpg","comments":" wow","description":"hulk , iron man","likes":"8","name":"avangeers"}] @ 0 of type org.json.jsonarray cannot converted jsonobject

but in php have edit

echo json_encode(array($result)); should'nt encode ?

actually there 2 problem in resposne given below solutions:-

1.your resposne not appropriate json object. response contains ?> @ end raised parsing error. removed api response.

2.your resposne json object. instead of using jsonarrayrequest use jsonobjectrequest class.

have peace , enjoy!!!
