remove wifi item from settings menu.

[lifusong]

Dears.

   why can't boot into os when remove system/etc/permissions/android.hardware.wifi.xml?

our design without wifh support.so we want remove Wi-Fi item form settings menu.

                } else if (id == R.id.wifi_settings) {

                    // Remove WiFi Settings if WiFi service is not available.

                    if (!getPackageManager().hasSystemFeature(PackageManager.FEATURE_WIFI)) {

                        removeTile = true;

                    }

and debug the code ,found this action will detect system/etc/permissions/android.hardware.wifi.xml.and checkout string "android.hardware.wifi"

so by the code designed ,we remove this file.

but can't boot into os.

and the debug show below info.   who can help me.
