I'm having problem with QtSDK deployment. My app runs fine in the simulator, but when I cannot get it working on QEMU/device.

1) QEMU: The default environment doesn't have QtQuick namespace, I tried getting it through 'apt-get update' then 'apt-get install qtquickcompat.' But I got "couldn't contact DNS" error. Is there any alternative way to get the package installed?
2) Device: I used 'build all' option to build the deb file then installed the file on device. But when I launched it all I got was black screen. I launched it in xterm and I saw the log messages, so it looked like the program was launched correctly and it was just the display part that was broken. There was no error messages from the system....
Btw, I have qtquickcompat package installed on my device already.

Anyone has any suggestion? Thanks in advance
