If your protocol has non-standard cache semantics, you can build a Cache. Entry yourself, but most requests are fine with something like this:. Volley calls parseNetworkResponse from a worker thread.

Volley calls you back on the main thread with the object you returned in parseNetworkResponse. Most requests invoke a callback interface here, for example:.

When I try to make the request, the first parameter Address is formatted by Volley before it is sent and the request is not accepted by the server. I tried just passing in the Address object but this wasn't serialized at all so it didn't work either.

I understand Volley is asynchronous, the requests happen in parallel and the responses sometimes are not immediate however I need some sort of progress bar or spinning wheel to give the user some feedback that the app is waiting for data.

It could be done with AsyncTask however it doesn't seem to be possible with Volley. I solved my problem by dumping Volley altogether and moving to Retrofit. Now it's working as I wanted.It is an independent data exchange format and is the best alternative for XML.
