Editing further to show my server side code:

Controller

  @PostMapping(path = ENDPOINT_MOBILE_OTP)
    public AuthenticationVO signInWithOTP(@Valid @RequestBody AuthenticationVO authenticationVO){
        System.out.println("login request is:-"+authenticationVO.toString());
        try {
        if (authenticationVO != null) {
            MultitenantUtility.request = httpRequest;
            String tenantId = multitenantUtility.resolveCurrentTenantIdentifier();
            if (tenantId != null) {
                multitenantUtility.setCurrentTenant(tenantId);
                authenticationVO = userService.checkLoginCredentialsWithOTP(authenticationVO);
            } else {
                System.out.println("request body is empty");
                //throw new DMPBadRequestException("Request body is empty");
            }
            }
        }
        catch(Exception e)
        {
            System.out.println("Excepton "+e);
        }
        finally
        {
            multitenantUtility.clearThreadLocal();
            LOGGER.info("authenticateUser - before returning");
        }
        
        return authenticationVO;
    }

Please check your Backend code as the android code looks fine. — Deepak Shukla, Dec 12 '20 at 10:16

Try to send JsonObjectRequest instead of StringRequest. Follow this answer

JsonObjectRequest request_json = new JsonObjectRequest(Request.Method.POST,url,object,
                new Response.Listener<JSONObject>() {
                    @Override
                    public void onResponse(JSONObject response) {
                        Log.i("info", response.toString());
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                VolleyLog.e("Error: ", error.getMessage());
            }
        });

I followed your answer but it is still sending an empty request to the server. Many more methods i tried earlier but nothing worked. – Disha Singh Dec 12 '20 at 06:11
use Rertrofit library instead of volley, Retrofit is more simple than volley, – Atik Faysal Dec 12 '20 at 06:52
did you follow this answer https://stackoverflow.com/questions/28344448/how-to-send-json-object-to-server-using-volley-in-android – Atik Faysal Dec 12 '20 at 06:53
I followed the link you shared, retrofit2 is sending an empty request whereas the request on postman is posting with success – Disha Singh Dec 12 '20 at 07:19

I have solved my problem it was a problem just added host in the header and the whole problem solved hence saved data in my database.

       @Override
                            public Map<String, String> getHeaders() throws AuthFailureError {
                                HashMap<String, String> headers = new HashMap<String, String>();
                                headers.put("Content-Type", "application/json; charset=utf-8");
                                headers.put("Host", "localhost:8080");

                        
                                return headers;
                            }

Thanks especially to @ATIK_FAYSAL for your kind efforts.
