Android正在检索MAC地址

Question

如果Internet连接已启用，我想检索MAC地址。 我用下面这段代码，但它仅适用于无线网络：

WifiManager manager = (WifiManager) getSystemService(Context.WIFI_SERVICE); 
WifiInfo info = manager.getConnectionInfo(); 
String address = info.getMacAddress()); 

我也试试这个，但我在getRuntime得到错误：

Process p = Runtime.getRuntime.exec("adb", "shell", "getprop", "ril.wifi_macaddr") 
BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()); 
String macAddress = br.readLine(); 

Answer 1

试试这个：

WifiManager manager = (WifiManager) getSystemService(Context.WIFI_SERVICE); 
WifiInfo deviceWifiInfo = manager.getConnectionInfo(); 
String address = deviceWifiInfo.getMacAddress(); 

和添加您的许可AndroidManifest.xml
