我正在使用此代码激活网络共享模式：

private void setWifiTetheringEnabled(boolean enable) {
    WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);

    Method[] methods = wifiManager.getClass().getDeclaredMethods(); 
    for (Method method : methods) {
        Log.e("teste", method.getName());
        if (method.getName().equals("setWifiApEnabled")) {
            try {
                method.invoke(wifiManager, null, enable);
            } catch (Exception ex) {
            }
            break;
        }
    }
}

我正在使用此代码连接设备（并阅读信息）

   br = new BufferedReader(new FileReader("/proc/net/arp"));

但是在这个文件（/proc/net/arp）中只有连接的设备，我想获得一些关于刚刚在网络共享模式下扫描我的手机的设备的信息（Mac 地址）。

执行 ntcfg 我的回报：

打电话exec("netcfg")；

/**
 * Execute a command in a shell
 * 
 * @param command
 *            command to execute
 * @return the return of the command
 */
public String exec(String command) {
    String retour = "";
    try {
        Runtime runtime = Runtime.getRuntime();

        Process p = runtime.exec(command);

        java.io.BufferedReader standardIn = new java.io.BufferedReader(
                new java.io.InputStreamReader(p.getInputStream()));
        java.io.BufferedReader errorIn = new java.io.BufferedReader(
                new java.io.InputStreamReader(p.getErrorStream()));
        String line = "";
        while ((line = standardIn.readLine()) != null) {
            retour += line + "\n";
        }
        while ((line = errorIn.readLine()) != null) {
            retour += line + "\n";
        }
    } catch (java.io.IOException e) {
        e.printStackTrace();
    }

    return retour;
}

它将在 shell 中执行“netcfg”命令并​​产生如下输出

lo       UP           127.0.0.1/8   0x00000049  00:00:00:00:00:00

sit0     DOWN         0.0.0.0/0     0x00000080  00:00:00:00:00:00

eth0     UP           0.0.0.0/0     0x00001003  78:c5:e5:a2:b2:d0

wlan0    DOWN         0.0.0.0/0     0x00001002  64:70:02:20:79:31

包括连接network interfaces , status , IP obtained & MAC address的 .

最后一个字段用于 MAC 地址。您必须从这个单个字符串中解析 MAC 地址。
