网络

1.向服务器发送http请求
一
public boolean sendPhoneInfo(String path){
    URL url = null;
    try {
        url = new URL(path);
        HttpURLConnection conn = (HttpURLConnection)url.openConnection();
        conn.setConnectTimeout(5000);
        conn.setRequestMethod("GET");
        if(conn.getResponseCode() == 200){
            return true;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

    return false;
}
二

new Thread(){
    @Override
    public void run(){
        App.isSuccess = sendPhoneInfo(path);
        Log.d("czDebug",path);
    }
}.start();

2.获取IP地址

public static String getLocalIpAddress(){
    try
    {
        for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();)
        {
            NetworkInterface intf = en.nextElement();
            for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();)
            {
                InetAddress inetAddress = enumIpAddr.nextElement();
                if (!inetAddress.isLoopbackAddress()&& InetAddressUtils.isIPv4Address(inetAddress.getHostAddress()))
                {
                    return inetAddress.getHostAddress().toString();
                }
            }
        }
    }
    catch (SocketException ex)
    {
        Log.e("WifiPreferenceIpAddress", ex.toString());
    }
    return null;
}
*依赖 httpclient-4.5.2.jar

3.WebView

源码

public class WebViewActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_web_view);

        //对象
        WebView webVeiw =(WebView)findViewById(R.id.webview);
        String url = "http://10.237.32.10";
        //设置
        webVeiw.setWebViewClient(new WebViewClient(){//本activity中显示
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return true;
            }
        });
        WebSettings settings = webVeiw.getSettings();
        settings.setJavaScriptEnabled(true);//启用js
        //载入
        webVeiw.loadUrl(url);
    }
}
