    <p>I'm working with Volley and org.json to pull a JSON from a users timeline in twitter. I received a "Error with Request" from my onErrorResponse. It doesn't seem to be a URL problem because I see the desired JSON in the LogCat. Here's the error log:</p> <pre><code>11-30 22:54:52.273: W/TweetLoader(18610): Error with request 11-30 22:54:52.273: W/System.err(18610): com.android.volley.ParseError: org.json.JSONException: Value [{"contributors":null,"text":"18-propeller copter might be the future of personal air travel, inventors say.\nhttp:\/\/t.co\/TMUtbF80Kp via @CNNTech","geo":null,"retweeted":false,"in_reply_to_screen_name":null,"possibly_sensitive":false,"truncated":false,"lang":"en","entities":{"urls":[{"display_url":"cnn.it\/1bWid4q","expanded_url":"http:\/\/cnn.it\/1bWid4q","indices":[79,101],"url":"http:\/\/t.co\/TMUtbF80Kp"}],"hashtags":[],"user_mentions":[{"id":42703075,"indices":[106,114],"screen_name":"cnntech","id_str":"42703075","name":"cnntech"}],"symbols":[]},"in_reply_to_status_id_str":null,"id":406951229278146560,"in_reply_to_user_id_str":null,"source":"&lt;a href=\"http:\/\/www.hootsuite.com\" rel=\"nofollow\"&gt;HootSuite&lt;\/a&gt;","favorited":false,"in_reply_to_status_id":null,"retweet_count":112,"in_reply_to_user_id":null,"created_at":"Sun Dec 01 01:01:48 +0000 2013","favorite_count":59,"id_str":"406951229278146560","place":null,"user":{"location":"","default_profile":false,"profile_background_tile":false,"statuses_count":36621,"lang":"en","profile_link_color":"004287","profile_banner_url":"https:\/\/pbs.twimg.com\/profile_banners\/759251\/1384971184","id":759251,"following":null,"favourites_count":4,"protected":false,"profile_text_color":"000000","contributors_enabled":false,"verified":true,"description":"Bringing you breaking news and the most talked about stories.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
