Hi,
one of my application is related to download data from web-service,
it is working fine when i have been downloading for less data(approx 300KB) taking time below 15 minute, but when i am downloading more data approx 1.5MB or more than 1.5MB then on Blackberry device it is taking more-than 20 minute, and after 20 minute it has been giving Exception"uncaught Exception ,Application is not responding;process Terminated"
some time on emulator also when downloading time is increasing more that 20 minute, same exception is coming.
if you know the Cause of Exception, and remedy then kindly reply me.
Thanks and regards
Imran Ali
