What happens if sdk's are missing - (advert aggregation)
<p>There are some mobile advertising aggregators (mopub for example) that insist on apps including the sdk's (which, correct me if I'm wrong, means jar files) of each separate ad network that they are aggregating.</p>

<p>One thing that has always bothered me is what would happen if I forgot to include one of the jar's? Would the program crash as soon as the aggregator attempted to serve an ad from that particular network? And if not, how is the crash avoided?</p>

<p><strong>EDIT:</strong> What I really want to do is test that my app is fully capable of displaying all the ads that the aggregator may serve.</p>
