If you want to put a StartApp ads banner in an Android app built with AndroidAnnotations, as the documentation says that you must do StartAppAd.init() in the onCreate() which you don't write when you use AA, well this is how to do
@AfterInject
public void pub() {
StartAppAd.init(this, "XXXXXX", "XXXX");
}
and of course, you insert the relevant xml copy-pasted from the StartApp pdf, in your layout

It works on my machine :)
