Unique Device ID in Android

Hi
Today, I would like to share some piece of code which can be used as unique id in android

/**

 * Its nothing but combine the Android ID with the WiFi MAC address in a

 * method that generates a UUID: Required Permition : <uses-permission

 * android:name="android.permission.ACCESS_WIFI_STATE" />

 * 

 * @param activity

 * @return

 */

public static String getUniqueID(Activity activity) {

 final String macAddr, androidId;

WifiManager wifiMan = (WifiManager) activity.getSystemService(Context.WIFI_SERVICE);

WifiInfo wifiInf = wifiMan.getConnectionInfo();

macAddr = wifiInf.getMacAddress();

androidId = "" + android.provider.Settings.Secure.getString(activity.getContentResolver(), android.provider.Settings.Secure.ANDROID_ID);

String UUID = androidId.hashCode() + "" + macAddr.hashCode();

// Maybe save this: deviceUuid.toString()); to the preferences.

return UUID;

}

I hope this might useful for some cases, Happy Codding
