Получить строку из массива JSON?

Question

Я пытаюсь ПОЛУЧИТЬ gadgetry_thumbnail_image путь из JSON массива с этим, но его возвращение нулевой:

JSONObject custom_fields = postObject.getJSONObject("custom_fields"); 
String thumbpath = custom_fields.optString("gadgetry_thumbnail_image"); 

Это массив JSON:

{"posts":[{"custom_fields":{"gadgetry_post_viewed":["12"],"gadgetry_tfuse_post_options":["a:58:{s:22:\"gadgetry_disable_image\";s:5:\"false\";s:22:\"gadgetry_disable_video\";s:5:\"false\";s:26:\"gadgetry_disable_post_meta\";s:5:\"false\";s:23:\"gadgetry_disable_author\";s:5:\"false\";s:31:\"gadgetry_disable_published_date\";s:5:\"false\";s:24:\"gadgetry_disable_coments\";s:5:\"false\";s:28:\"gadgetry_disable_author_info\";s:5:\"false\";s:19:\"gadgetry_page_title\";s:13:\"default_title\";s:21:\"gadgetry_custom_title\";s:0:\"\";s:21:\"gadgetry_single_image\";s:0:\"\";s:30:\"gadgetry_single_img_dimensions\";a:2:{i:0;s:3:\"320\";i:1;s:3:\"250\";}s:28:\"gadgetry_single_img_position\";s:10:\"alignright\";s:24:\"gadgetry_thumbnail_image\";s:104:\"http:\/\/www.mysite.com\/wp-content\/uploads\/2015\/11\/11666271_761774897268291_544140090628098983_n.jpg\";s:27:\"gadgetry_thumbnail_position\";s:7:\"noalign\";s:19:\"gadgetry_video_link\";s:0:\"\";s:25: 

Это полный массив

«Массив», который вы предоставили, является неполным. У него есть незамкнутая строка.
