JsonParse.Java URLからjson配列オブジェクトを取得しようとしていますが、パーシングエラー
を投げ、CountriedBeanが私のPOJOクラスです。
parse_jsonだけでListViewコントロールを持っており、 parse_json_viewは4のTextViewの

を持っている誰もが私を助けてくださいすることができ................

URLの応答https://github.com/SaiNitesh/REST-Web-services/blob/master/RESTfulWS/json_file.jsonはHTMLページなので、例外が発生します。

代わりにhttps://raw.githubusercontent.com/SaiNitesh/REST-Web-services/master/RESTfulWS/json_file.jsonをご利用ください。
