 i folks,

i've been struggling to find a way to read in a url value from within
a tag in an xml feed. im so close but i just can't seem to crack it.

i started out using this
as a guide which works great but customising it to read in an
attribute of an element is causing me problems.

the feed is here:

within the xml's 'item' element is <media:thumbnail width="X"
height="X" url="X"/> it's the url attribute im after. i can get the
title back fine but the structure of the media:thumbnail tag means im
missing something!

what's interesting(!?) is the fact that when i remove the loop and
only go for the first item, i get the image back! the line with strImg
= imgElement.getAttribute("url") just won't work within the loop...
any ideas are greatly appreciated.

this is very rough n ready, im learning :-)

1. Please share the info about the problem "app is not visible on Android Market"

Hi, All.

The end of last year, there were discussions about the problem
regarding to the visibility of apps on Android Market.

2. Share files with different Activities running in different processes in a application.


      I would like to share a cache file across activities, which are
running in different processes but in a same application.

      The operations on the file are:
      Read: context.openFileInput->read fileInputStream->close
      Delete: context.deleteFile
      Write:context.openFileOuput->Write to fileOutputStream  ->close

      So, is there any way to make it thread safe (probably not
"thread safe", should we call it "activities safe" or "process
safe" ?:-) )

Thanks a lot.
