By read the report api documents,
it seems if I have to get completely ad informations,
it's better to use 'ad performance report' rather than 'AdGroupAdService'.
===
From the document 'Reference' page, I may get these informations(attachment1),
but by using `com.google.api.ads.adwords.axis.v201702` ,
there are few fields I can choose, and none of them looks like I can get enough informations corresponding to attached picture
What is the correct way to get full ad informations ?
Thanks.
