    <p>Can anyone help me dissect this error log? The class throwing this is almost identical to another class that works fine in the same program. The only difference is that I have added a List and am passing parameters to the url for the json request</p> <pre><code> protected String doInBackground(String... args) { // Building Parameters List&lt;NameValuePair&gt; params = new ArrayList&lt;NameValuePair&gt;(); // getting JSON string from URL //params.add(new BasicNameValuePair("category","cat")); </code></pre> <p>Line 74: JSONObject json = jParser.makeHttpRequest(url_get_channels, "GET", params);</p> <pre><code> // Check your log cat for JSON reponse Log.d("All Products: ", json.toString());

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.
