android - 画像解析エラーのあるリストビューの JSON データ

Question

jsonparser を使用して、json 応答から取得したデータと画像を解析しています。画像出力を解析するためにこのコードを含めると、D/AndroidRuntime(441): Shutting down VM D/dalvikvm(441): Debugger has detached; になります。オブジェクトレジストリには 1 個のエントリがありました

JSONArray attachments = json.getJSONArray(KEY_ATTACHMENTS);
                for(int j = 0; j < attachments.length(); j++){
                    JSONObject d = attachments.getJSONObject(j);
                    JSONObject images = d.getJSONObject(KEY_IMAGES);
                    String thumbnail = d.getString(KEY_THUMB_URL);

                    JSONObject thumnails = d.getJSONObject(KEY_THUMB_URL);
                    String url = author.getString(KEY_URL);

コンテンツの解析に問題がありますか? どんな体でも助けられますか画像は出力のデータとともに表示されます。私のJSONレスポンスは

現在の json を次のように解析します。

   JSONObject json=new JSONObject("pass your json string here");

  JSONArray arrjson = json.getJSONArray("posts");

   for(int j = 0; j < arrjson.length(); j++){
        JSONObject jsonimages = attachments.getJSONObject(j);

       JSONArray attachmentsimages = jsonimages.getJSONArray("attachments");

      for(int i = 0; i < attachmentsimages.length(); i++){

           JSONObject imagesjson = attachmentsimages.getJSONObject(i);

           JSONObject imagesjsonnew = imagesjson.getJSONObject("images");
           JSONObject thumnailsimages = imagesjsonnew.getJSONObject("thumbnail");

           String url = thumnailsimages.getString("url");
     }

}
