Android Volley Post Request Header not changing

Question

I am using Android Volley library to send POST request. And for POST request

• Header is Content-Type:application/js

Answer 1

I found I had to override getBodyContentType() in order to get the Content-Type header to update correctly:

    public String getBodyContentType()
    {
        return "application/json; charset=utf-8";
    }

Here is my question with some more details on this issue:

• Volley Content-Type header not updating

Answer 2

Using network sniffing tool like Wireshark,I found that my error lay on wrong HTTP header. Then using Chrome DHC plugin

I found that Header Content-Type should be application/json; charset=utf-8and I was continuously using

    Map<String, String> header = new HashMap<String, String>();
    header.put("Content-Type", "application/json");

instead of

    Map<String, String> header = new HashMap<String, String>();
    header.put("Content-Type", "application/json; charset=utf-8");

Using proper Header solved my issue
