I'm learning how to use Google Volley these days. It's very convenient for fast networking. It seems that all the requests are running in background in Volley. For example:
volleyRequestQueue.add(new JsonObjectRequest(Method.POST, SIGNUP_URL, reqBody, new SignUpResponseListener(), new MyErrorListener()));
Using the above code, we can make a POST call which runs in background(non-blocking way). Now my question is : Is it possible to make the POST call in the blocking way? Why I need a blocking way to make a REST call? Because some calls, like sign in, should be done before doing something else.
Thanks
Volley supports blocking request via RequestFutures. You create a normal request but set its callbacks as your request future, which is just volley's extension of a standard java futures. The call to future.get() will block.
It looks something like this
RequestFuture<JSONObject> future = RequestFuture.newFuture();
JsonObjectRequest request = new JsonObjectRequest(Method.POST, SIGNUP_URL, reqBody, future, future)
volleyRequestQueue.add(request);
try {
JSONObject response = future.get();
} catch (InterruptedException e) {
} catch (ExecutionException e) {
}
