android 获取平板电脑序列号

Question

从网上找了一个获取序列号的代码，为何不好使？真机上取的也是0000000000

Answer 1

我也遇到这个问题了 LZ解决木有哇o(>﹏<)o

Answer 2

我也要取平板电脑的序列号，用了很多种方法都不行，Mac地址能取到。

Answer 3

取mac方法： private String getLocalMacAddress() {   
        WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);   
        WifiInfo info = wifi.getConnectionInfo();   
        return info.getMacAddress();   
    }
