Android正在檢索MAC地址

Question

如果Internet連接已啓用，我想檢索MAC地址。 我用下面這段代碼，但它僅適用於無線網絡：

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

我也試試這個，但我在getRuntime得到錯誤：

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

試試這個：

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

和添加您的許可AndroidManifest.xml
