Unable to connect to network server while application in foreground

[netlogins]

Hi All,

I am facing quite unexpected response of my application on few devices like N78 and N80. My application connects to a remote server to fetch data. It works perfect on many devices but on above two devices, it remains on progress screen(where animation is displayed using framed image after 1000µs interval), untill I send it to background. If I send it to background, data is downloaded successfully but if it's in foreground I can see only animation. I've observed that after waiting long on this screen, as soon as I send it to background, the gprs connectivity icon of phone is appeared then.

I'm unable to figure out the reason. I'm not sure if I could face the same problem on some other devices too.

bet: I've tested this successfully on E65, N73, N95, E71


What could be the reason?

Thanks,

Maybe you could check with Y-Tasks::trace whether your devices CPU is running near it max capability, also try slowing the animation and see whether it helps.

Hi Yucca,

Thanks for the response, I checked cpu usage using y-task:trace, and its in normal mode. But again as soon as I switch from my app to ytrace, data is downloaded at the backend, but if my app remains in foucs it doesn't connect at all.

Now I've increased delay from 1000µs to 10000µs and its working fine . It's strange as none other application was running on the phone but it is :P. It was working perfect with 0ms delay on other phones, I mentioned earlier.

Thanks for the hints Yucca.

Are you sure it is milli seconds, and not micro-seconds you are dealing with ? 1000ms would be 1 sec and 10'000ms would be 10 sec, but with micro seconds, 1000 would mean that the frame is changed 1000 times a second.., thus maybe you think what the actual framerate you should try having should be.

O sorry my mistake, time interval in microseconds.
