I'm having some issues trying to use exchange webservices for java. I'm getting following NoSuchMethodError.
java.lang.NoClassDefFoundError: Failed resolution of: Lorg/apache/http/client/protocol/HttpClientContext;
I've tried reinstalling ews-java-api several times but it hasnt been solving the problem as i believed it would.
I'm currently working in Android Studio.
