android GUI saying "Unable to scan for networks"

[Sudha Daram]

Hi, I have ported my wlan driver to android.
When wifi is on, am able to load the driver and scan for networks.
But GUI is saying "Unable to scan for networks" and it makes reloading
of driver continuously.

But my driver able to scan APs and list down to wpa_supplicant.

where could be the problem? why the supplicant is not displaying the
info?
Please let me know if am missing on some permissions...
