Android16 AP热点修改默认密码为12345678

在某些项目，需要设置WiFi热点密码默认为12345678，修改如下：

在packages\modules\Wifi\service\java\com\android\server\wifi\WifiApConfigStore.java里面generatePassword()方法修改：

private static String generatePassword() {
        // Characters that will be used for password generation. Some characters commonly known to
        // be confusing like 0 and O excluded from this list.
        final String allowed = "23456789abcdefghijkmnpqrstuvwxyz";
        final int passLength = 15;

        StringBuilder sb = new StringBuilder(passLength);
        SecureRandom random = new SecureRandom();
        for (int i = 0; i < passLength; i++) {
            sb.append(allowed.charAt(random.nextInt(allowed.length())));
        }
		return "12345678";
        //return sb.toString();
    }

这样就默认为12345678了
