You can create an HTML page containing an anchor link that users click to populate the Account Provider field. The following is the format of the anchor link:
<html>
<body><a href="intent://x-callback-url/register?providerUrl= https://IDP_server_dns_name:port#Intent;scheme=comnetiqauth;package=com.netiq.mobileaccessforandroid;end;">Register</a></body>
</html>
For example:
<html> <body><a href="intent://x-callback-url/register?providerUrl= https://idp.acme.com:8443#Intent;scheme=comnetiqauth;package=com.netiq.mobileaccessforandroid;end;">Register</a></body> </html>
