Android：擷取裝置的mac地址可靠的方法

標籤：android   wifi   mac   

/** * 擷取裝置的mac地址 *  * @param ac * @param callback *            成功擷取到mac地址之後會回調此方法 */public static void getMacAddress(final Activity ac, final SimpleCallback callback) {final WifiManager wm = (WifiManager) ac .getSystemService(Service.WIFI_SERVICE);// 如果本次開機後開啟過WIFI，則能夠直接擷取到mac資訊。立刻返回資料。WifiInfo info = wm.getConnectionInfo();if (info != null && info.getMacAddress() != null) {if (callback != null) {callback.onComplete(info.getMacAddress());}return;}// 嘗試開啟WIFI，並擷取mac地址if (!wm.isWifiEnabled()) {wm.setWifiEnabled(true);}new Thread(new Runnable() {@Overridepublic void run() {int tryCount = 0;final int MAX_COUNT = 10;while (tryCount < MAX_COUNT) {final WifiInfo info = wm.getConnectionInfo();if (info != null && info.getMacAddress() != null) {if (callback != null) {ac.runOnUiThread(new Runnable() {@Overridepublic void run() {callback.onComplete(info.getMacAddress());}});}return;}SystemClock.sleep(300);tryCount++;}// 未擷取到mac地址if (callback != null) {callback.onComplete(null);}}}).start();}

SimpleCallback是一個簡單的回調介面：

public interface SimpleCallback {void onComplete(String result);}
