    <p><code>mysql_fetch_assoc</code> returns an array. So in your code you get something like:</p> <pre><code> echo json_encode(array('Course' =&gt; array())); </code></pre> <p>the result is a string: <code>{"Course":[]}</code>. In JSON this is an object. so you need to fetch it with:</p> <pre><code>JSONObject jsonObject = new JSONObject(jsonString); JSONArray jArray = jsonObject.getJSONArray("Course"); </code></pre> <p>See also: <a href="https://stackoverflow.com/questions/4244879/reading-a-json-array-in-android">Reading a Json Array in android</a></p> <p><strong>update</strong></p> <p>in your php:</p> <pre><code>function verifyCourse($courseCode){ $result = mysql_query("SELECT * FROM Course WHERE CourseCode = \"$courseCode\" LIMIT 1"); $rows = array(); while ($r = mysql_fetch_assoc($result)) { $rows[]= $r; } header('Content-type: application/json'); return json_encode(array('Course' =&gt; $rows)); exit; } </code></pre> <p>Which outputs a string like:</p> <pre><code> {"Course":[{"key1":"value1","key2":"value2"},{"2key1":"2value1","2key2":null}]} </code></pre> <p>in your java code:</p> <pre><code> JSONObject jsonObject = new JSONObject(builder.toString()); JSONArray jArray = jsonObject.getJSONArray("Course"); for(int i = 0; i &lt; jArray.length(); i++){ JSONObject jObject = jArray.getJSONObject(i); Iterator&lt;String&gt; keys = jObject.keys(); storage = new HashMap&lt;String, String&gt;(); while( keys.hasNext() ){ String key = (String)keys.next(); storage.put(key, jObject.get(key).toString()); } results.add(storage); } </code></pre>

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.
