Volley – POST/GET parameters

by

For the GET parameters there are two alternatives: First: As suggested in a comment bellow the question you can just use String and replace the parameters placeholders with their values like: String uri = String.format(“http://somesite.com/some_endpoint.php?param1=%1$s&param2=%2$s”, num1, num2); StringRequest myReq = new StringRequest(Method.GET, uri, createMyReqSuccessListener(), createMyReqErrorListener()); queue.add(myReq); where num1 and num2 are String variables that contain … Read more

How to send a “multipart/form-data” POST in Android with Volley

by

I might be wrong on this but I think you need to implement your own com.android.volley.toolbox.HttpStack for this because the default ones (HurlStack if version > Gingerbread or HttpClientStack) don’t deal with multipart/form-data.

Can I do a synchronous request with volley?

java.lang.IllegalStateException: Fragment not attached to Activity

This error happens due to the combined effect of two factors: The HTTP request, when complete, invokes either onResponse() or onError() (which work on the main thread) without knowing whether the Activity is still in the foreground or not. If the Activity is gone (the user navigated elsewhere), getActivity() returns null. The Volley Response is … Read more
