    <p>I am trying to parse a rather large XML file - 1MB+, but I am having some difficulties. I first tried to add the xml file to the res/xml and parse it with the XmlResourceParser, but I got an exception saying "Data exceeds UNCOMPRESS_DATA_MAX". After a bit of research I found out that the compressed files have to be uncompressed in memory before reading and that this restriction doesnt apply for raw files. However when trying to parse the xml file from the res/raw folder with the SAXParser, I get an IOException, without any message and stacktrace:</p> <pre><code>SAXParserFactory spf = SAXParserFactory.newInstance(); SAXParser sp = spf.newSAXParser(); XMLReader xr = sp.getXMLReader(); xr.setContentHandler(myXMLHandler); InputSource src = new InputSource(stream); xr.parse(src); // IOException </code></pre> <p>From what I understand those memory restrictions do not apply to raw resources, but what is causing this exception then?</p> <p>Here is the stacktrace from logcat:</p> <pre><code>11-11 23:47:50.729: WARN/System.err(4886): java.io.IOException 11-11 23:47:50.739: WARN/System.err(4886): at android.content.res.AssetManager.readAsset(Native Method) 11-11 23:47:50.749: WARN/System.err(4886): at android.content.res.AssetManager.access$800(AssetManager.java:36) 11-11 23:47:50.759: WARN/System.err(4886): at android.content.res.AssetManager$AssetInputStream.read(AssetManager.java:542) 11-11 23:47:50.759: WARN/System.err(4886): at org.apache.harmony.xml.ExpatParser.parseFragment(ExpatParser.java:504) 11-11 23:47:50.769: WARN/System.err(4886): at org.apache.harmony.xml.ExpatParser.parseDocument(ExpatParser.java:467) 11-11 23:47:50.779: WARN/System.err(4886): at org.apache.harmony.xml.ExpatReader.parse(ExpatReader.java:329) 11-11 23:47:50.790: WARN/System.err(4886): at org.apache.harmony.xml.ExpatReader.parse(ExpatReader.java:286) </code></pre>

    1. COPlease post the output of logcat. It is not possible to have an exception thrown without getting at least a logcat error level output.

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.
