1)在frameworks\base\packages\SettingsProvider\res\values\default.xml

  <bool name="def_ethernet_on">true</bool>  改成true

  <bool name="def_ethernet_mode">true</bool> 添加以下這兩句  

     <bool name="def_ethernet_conf">true</bool>

      <string name="def_ethernet_ifname" translatable="false">eth0</string>

2)在frameworks\base\packages\SettingsProvider\src\com\android\providers\settings\DatabaseHelper.java 添加

       loadBooleanSetting(stmt, Settings.Global.ETHERNET_CONF, R.bool.def_ethernet_conf)

       loadStringSetting(stmt, Settings.Global.ETHERNET_IFNAME, R.string.def_ethernet_ifname)
