    <p>In your situation I would pick JSON over XML for all the reason's stated in the following post: <a href="http://ajaxian.com/archives/json-vs-xml-the-debate" rel="nofollow">http://ajaxian.com/archives/json-vs-xml-the-debate</a></p> <p>Plus, in android, there are JSON Array's built in by default so you don't have to do any extra passing of the code.</p> <pre><code>return new JSONArray("my json string goes here..."); </code></pre> <p>Since we are talking about a mobile device, I would always generate changes in your php script rather than have a full sync as this will be a lot smaller in size that a full sync. However, you will need to give your user a option to do a full re-sync if this is applicable to your app. I would use a SQLite database to store the data and only update the changes in that.</p> <p>To also make the stream smaller, you can gzip compress your output from php as this can be natively read by the android device. In my app, I compress 500kb down to ~110kb before transmitting, a huge saving on performance. Here a partial example of how to read the stream:</p> <pre><code>InputStream in = null; HttpURLConnection httpConn = null; // you will have to write your on code for this bit. if (httpConn.getContentEncoding() != null) { String contentEncoding = httpConn.getContentEncoding().toString(); if (contentEncoding.contains("gzip")) { in = new GZIPInputStream(httpConn.getInputStream()); } } else { in = httpConn.getInputStream(); } </code></pre> <p>I hope that this all makes sense, it's been a long day programming :)</p> <p>Stu</p>

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.
