No. Look at the hardware/libhardware/wifi/wifi.c file
There is a static path for the sockets file, that is used by android.

static const char IFACE_DIR[]           = "/data/system/wpa_supplicant";

If the directory exists it uses it

int wifi_connect_to_supplicant()
    char ifname[256];
    static int cleaned_up = 0;

    property_get("wifi.interface", iface, "sta");

    if (access(IFACE_DIR, F_OK) == 0) {
        snprintf(ifname, sizeof(ifname), "%s/%s", IFACE_DIR, iface); 
<----- this one
    } else {
        strlcpy(ifname, iface, sizeof(ifname));

ifname is eth0.

The wpa_supplicant conf is modified according to the 
/data/system/wpa_supplicant directory

like this:

ctrl_interface=DIR=/data/system/wpa_supplicant GROUP=1010

I'm not sure but I force the UNIX socket in target config file.


Now I can se the wireless in the interface but when I choose one of 
them, android open a dialog box
and leave the keyboard in background.
