Attach advertisement SDK to Qt Android application

[jiangcaiyang]

I've developed Qt for years but new to Android development. I know that we can develop Android applications using Qt. However I got stuck on how to attach ad SDK into application. Is there any useful tips? Thanks in advance.
PS: The SDK is provided with a jar file and a user manual.
