//Vendor HAL via HIDL

frameworks/opt/net/wifi/service/java/com/android/server/wifi/WifiVendorHal.java

hal的接口，可以生成IWifi.java

hardware/interfaces/wifi/1.0/IWifi.hal

hardware/interfaces/wifi/1.4/default

hardware/interfaces/wifi/1.4/default/wifi.cpp (startWifi在这儿)

（1）startHal方法内部调用

startHal()->startHal()->WifiVendorHal.startVendorHal()->HalDeviceManager.start()->HalDeviceManager.startWifi()

./net/wifi/service/java/com/android/server/wifi/WifiNative.java:612:

mHostapdHal.removeAccessPoint

./net/wifi/service/java/com/android/server/wifi/WifiNative.java:631:

setupInterfaceForSoftApMode

createApIface

InterfaceDestoyedListenerInternal-->onDestroyed

onInterfaceDestroyed

onSoftApInterfaceDestroyed

frameworks/opt/net/wifi/service/java/com/android/server/wifi/SoftApManager.java

mApInterfaceName = mWifiNative.setupInterfaceForSoftApMode

startSoftAp

frameworks/opt/net/wifi/service/java/com/android/server/wifi/ActiveModeWarden.java

stopSoftApModeManagers

WifiCond

wificond 启动hostapd,wpa_supplicant以及扫描

在frameworks/opt/net/wifi/service/java/com/android/server/wifi/WifiInjector.java

说明wificond应该是个系统服务

mWifiCondManager = (WifiNl80211Manager) mContext.getSystemService(
Context. WIFI_NL80211_SERVICE);

mWifiNative = new WifiNative(
mWifiVendorHal, mSupplicantStaIfaceHal, mHostapdHal, mWifiCondManager,
mWifiMonitor, mPropertyService, mWifiMetrics,
wifiHandler, new Random(), this);

为什么会需要wificond还不太清楚
