Thanks for responding, I appreciate it!
There is another complication I realize I forgot to mention. The AAR needs to
support intents. So when the Android app is built we need to be able to put our
intents, mapped to the appropriate classes into the manifest. Is there anyway
to do that in 'stock' XWalk? And how would we include the AAR anyway? We still
need XWalk's build to include it even if we are going to call it via reflection.
It feels like the embedding API might be cleaner since this would, if I'm
understanding it correctly, basically let us write an Android app that does
whatever we want and then just call XWalk to handle the rest. But you mentioned
"this way needs some additional effort". The docs didn't mention any open
issues. Could you please help me understand what sort of problems I'm likely to
face?
I'm just trying to understand where the challenges are before I commit to a
path.
Thank you and thank you especially for XWalk!
Yaron

Hi Goland
Thanks for using Crosswalk. Since the external Crosswalk extension on Android
is loaded at runtime through Java reflection mechanism, if you want to call out
other modules (e.g. AAR as you mentioned), one thing you may need to do is to
make JVM be able to load the required classes at runtime, e.g. via Java
reflection.
Another alternative way is to use Crosswalk Embedding API (see
https://crosswalk-project.org/#documentation/apis/embedding_api) to generate
an Android project, but this way needs some additional effort.
Thanks...Hongbo
