QML nfcchat app Black Screen prblm

[MamdouhAlShamy]

hi,

while i was deploying "nfcchat":https://projects.developer.nokia.com/nfcchat on C7 Anna
i got a black screen on the device instead of the expected UI

first i tried the sis
then compiled the code
in both cases i got the black screen

despite it runs on the Simulator :S :S

extra info on my dev tools versions
Qt 4.7.4 on PC and installed its sis on the C7
QtMobility 1.2 and installed its sis on the C7 also

hint: the device can run other QML and NFC apps like "NFC P2P Example":http://projects.developer.nokia.com/P2PExample

any suggestions

thx

after some investigation i got the solution--

if u faced the same problem as described above
do these steps

connect ur testing device

go to Projects tab then switch to Symbian device Run tab

click on the small blue button w i in it

if u found
@Qt Quick components version: Not installed@

go to <QtSDK-Dir>/Symbian/sis/Symbian^3/qt-components

and install qt-components_1_0.sis

now if u re-press that info button u will get
@
Qt Quick components version: 1.0.0
@
and can install qml apps
