@WenqiangTu Your stack trace suggests that you haven't run the build steps properly.

How do I know that?

    at android.javax.naming.directory.InitialDirContext.<init>(InitialDirContext.java:87) 
    at microsoft.exchange.webservices.data.dns.DnsClient.dnsQuery(DnsClient.java:79)

DnsClient#dnsQuery calls InitialDirContext constructor at line 79, which only happens in ews-java-api's original DnsClient class. This class is being excluded and replaced with a patched one.

Please let me know if you have any other issues.
