    Error giving volley

    i also had this issue which solved by Retrofit. This is the first time I' m working with JSON but I' m experimenting with POST requests. I want to make a POST request to this website com/ api. My code works when I use an asynctask + httppost private static final String url. When I was using the content type in header callback, the 400 response status I was getting in logcat. w( " Volley Error", error. I tried to narrow it down and found out that it only gives me 400 error on POST requests with Body. apparently after changing to HTTPS volley is sending empty bodies. and I didn' t understood why. at the end I found my. But they still could not find the reason behind this error. And sometimes, the same code works on one server and gives error on some other server. So, Lets discuss here that why Volley gives this 400 Bad Request error seems the problem lies in the value in the map. [ ] could not be escaped. put( " Authorization", " [ My SAS Key] " ) ;.

    What I did was, while creating the params, I encoded key and value with UTF- 8.
