I think we need to add #include "base/android/scoped_java_ref.h" for this here
and elsewhere.

+using base::android::ScopedJavaLocalRef;
 
 namespace cronet {
 namespace {
 
 net::RequestPriority ConvertRequestPriority(jint request_priority) {
   switch (request_priority) {
     case REQUEST_PRIORITY_IDLE:
       return net::IDLE;
     case REQUEST_PRIORITY_LOWEST:
       return net::LOWEST;
