【代码】Android SDK平台获取高唯一性设备识别码

注意:由于获取的设备信息完全可以通过诸如hook拦截等手段伪造,因此不能简单通过代码获取到数据作为判断用户身份的唯一凭据!(某些apk竟然通过imsi,imei来为用户自动登录...)

private static String getUniqueID(Context paramContext)  {    for (;;)    {      byte[] arrayOfByte;      int i;      try      {        String str1 = ((TelephonyManager)paramContext.getSystemService("phone")).getDeviceId();        String str2 = "35" + Build.BOARD.length() % 10 + Build.BRAND.length() % 10 + Build.CPU_ABI.length() % 10 + Build.DEVICE.length() % 10 + Build.DISPLAY.length() % 10 + Build.HOST.length() % 10 + Build.ID.length() % 10 + Build.MANUFACTURER.length() % 10 + Build.MODEL.length() % 10 + Build.PRODUCT.length() % 10 + Build.TAGS.length() % 10 + Build.TYPE.length() % 10 + Build.USER.length() % 10;        String str3 = Settings.Secure.getString(paramContext.getContentResolver(), "android_id");        String str4 = ((WifiManager)paramContext.getSystemService("wifi")).getConnectionInfo().getMacAddress();        String str5 = str1 + str2 + str3 + str4;        try        {          MessageDigest localMessageDigest2 = MessageDigest.getInstance("MD5");          localMessageDigest1 = localMessageDigest2;        }        catch (NoSuchAlgorithmException localNoSuchAlgorithmException)        {          String str7;          localNoSuchAlgorithmException.printStackTrace();          MessageDigest localMessageDigest1 = null;          continue;        }        localMessageDigest1.update(str5.getBytes(), 0, str5.length());        arrayOfByte = localMessageDigest1.digest();        localObject = new String();        i = 0;        if (i >= arrayOfByte.length)        {          str7 = ((String)localObject).toUpperCase();          Log.e("uid", str7);          return str7;        }      }      catch (Exception localException)      {        localException.printStackTrace();        return "";      }      int j = 0xFF & arrayOfByte[i];      if (j <= 15) {        localObject = localObject + "0";      }      String str6 = localObject + Integer.toHexString(j);      Object localObject = str6;      i++;    }  }
