Thanks hackbod, for replying. As a well wisher, I must say the slowness of the Android UI really bothers me. It took 17 seconds to parse an XML file and load the UI widgets - a list of compound items. The same list loaded almost instantaneously - too fast to measure by hand, but less than half a second - using a Java Swing application. The parsing and loading code was identical - except that in Android one has to use the SAXParserFactory class, and in Swing, I could use XMLReaderFactory directly. I shall follow your advice and use the profiler but not immediately as I still have a lot of coding to do and am very nervous and stressed out :) thanks, Anil
