android 8.0 設置Ethernet的靜態IP

設置靜態IP的方法如下:

... mEthManager = (EthernetManager) mContext.getSystemService(Context.ETHERNET_SERVICE);...private void setEthernetConfig(){        try {            StaticIpConfiguration staticIpConfiguration = new StaticIpConfiguration();            InetAddress mIpAddr = NetworkUtils.numericToInetAddress(tIpAddressString);            LinkAddress mIpAddress = new LinkAddress(mIpAddr,tNetworkPrefixLength);            InetAddress mGateway = NetworkUtils.numericToInetAddress(tGatewayString);            ArrayList mDnsServers = new ArrayList();            mDnsServers.add(NetworkUtils.numericToInetAddress(tDnsFirstString));            mDnsServers.add(NetworkUtils.numericToInetAddress(tDnsSecondString));            staticIpConfiguration.ipAddress = mIpAddress;            staticIpConfiguration.gateway = mGateway;            staticIpConfiguration.dnsServers.addAll(mDnsServers);            if(mConnectionTypeSelect.contains(CONNECT_TYPE_STATIC)) {                if (mStaticProxySelect.contains(PROXY_NONE)) {                    config = new IpConfiguration(IpConfiguration.IpAssignment.STATIC, IpConfiguration.ProxySettings.NONE, staticIpConfiguration, null);                } else if (mStaticProxySelect.contains(PROXY_STATIC)) {                    config = new IpConfiguration(IpConfiguration.IpAssignment.STATIC, IpConfiguration.ProxySettings.STATIC, staticIpConfiguration, ProxyInfo.buildDirectProxy(null, 0));                } else if (mStaticProxySelect.contains(PROXY_PAC)) {                    config = new IpConfiguration(IpConfiguration.IpAssignment.STATIC, IpConfiguration.ProxySettings.PAC, staticIpConfiguration, ProxyInfo.buildDirectProxy(null, 0));                } else if (mStaticProxySelect.contains(PROXY_UNASSIGNED)) {                    config = new IpConfiguration(IpConfiguration.IpAssignment.STATIC, IpConfiguration.ProxySettings.UNASSIGNED, staticIpConfiguration, ProxyInfo.buildDirectProxy(null, 0));                } else {                    config = new IpConfiguration(IpConfiguration.IpAssignment.STATIC, IpConfiguration.ProxySettings.NONE, staticIpConfiguration, null);                }            }else{                config = new IpConfiguration(IpConfiguration.IpAssignment.DHCP, IpConfiguration.ProxySettings.NONE, null, ProxyInfo.buildDirectProxy(null,0));            }            mEthManager.setConfiguration(config);        }catch (Exception e){            e.printStackTrace();        }        Settings.System.putString(mContext.getContentResolver(),                Settings.System.KEY_ETHERNET_CONNECTION_TYPE, mConnectionTypeSelect);        Settings.System.putString(mContext.getContentResolver(),                Settings.System.KEY_ETHERNET_STATIC_IP, tIpAddressString);        Settings.System.putString(mContext.getContentResolver(),                Settings.System.KEY_ETHERNET_STATIC_GATEWAY, tGatewayString);        Settings.System.putString(mContext.getContentResolver(),                Settings.System.KEY_ETHERNET_STATIC_SUBMASK, tSubMaskString);        Settings.System.putString(mContext.getContentResolver(),                Settings.System.KEY_ETHERNET_STATIC_DNS_FIRST, tDnsFirstString);        Settings.System.putString(mContext.getContentResolver(),                Settings.System.KEY_ETHERNET_STATIC_DNS_SECOND, tDnsSecondString);        Settings.System.putString(mContext.getContentResolver(),                Settings.System.KEY_ETHERNET_STATIC_PROXY, mStaticProxySelect);    }

設置好之後需要在/frameworks/opt/net/ethernet/java/com/android/server/ethernet/EthernetNetworkFactory.java 中做如下處理[不然會出現ifconfig 可以看到設置的static IP,但是不能上網,設置中也不能看到IP]
