Alternatively, this could be wrapped with 
#if !defined(ANDROID_OS) to keep the DCHECK available on non-Android platforms.

Outputting requests from two different NetLogs (Or from a NULL NetLog and a
non-NULL one) to a single observer really makes no sense.

I'd rather just have the call to  PrePopulateEventList() in net_internals_ui
skipped entirely on Android.

Done.

     for (const auto& request : *context->url_requests()) {
       requests.push_back(request);
     }
