Android Volley Error: com.android.volley.ClientError

Question

I would like to know how I can rectify this issue. Research and replacement of code has been done however the problem persists.

Here is my code working with volley.

private void Regist(){
    loading.setVisibility(View.VISIBLE);
    btn_regist.setVisibility(View.GONE);

    final String name = this.name.getText().toString().trim();
    final String email = this.email.getText().toString().trim();
    final String password = this.password.getText().toString().trim();

    StringRequest stringRequest = new StringRequest(Request.Method.POST, URL_REGIST,
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    try{
                        JSONObject jsonObject = new JSONObject(response);
                        String success = jsonObject.getString("success");

                        if(success.equals("1")) {
                            Toast.makeText(RegisterActivity.this, "Register Success!", Toast.LENGTH_SHORT).show();
                        }

                    }catch (JSONException e) {
                        e.printStackTrace();
                        Toast.makeText(RegisterActivity.this, "Register Error!" + e.toString(), Toast.LENGTH_SHORT).show();
                        loading.setVisibility(View.GONE);
                        btn_regist.setVisibility(View.VISIBLE);

                    }

                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    Toast.makeText(RegisterActivity.this, "Register Error!" + error.toString(), Toast.LENGTH_SHORT).show();
                    loading.setVisibility(View.GONE);
                    btn_regist.setVisibility(View.VISIBLE);

                }
            })
    {
        @Override
        protected Map<String, String> getParams()throws AuthFailureError {
            Map<String, String> params = new HashMap<>();
            params.put("name", name);
            params.put("email", email);
            params.put("password", password);
            return super.getParams();
        }
    };

    RequestQueue requestQueue = Volley.newRequestQueue(this);
    requestQueue.add(stringRequest);

Since I receive 'com.android.volley.ClientError' I assume this is wrong but if you require the rest of the code please comment!

Answer 1

Replace

return super.getParams()

By

return params;

Answer 2

This is also happen when the provided URL or IP address is wrong. If you are using localhost, make sure the IP address is correct. You can done this by CMD command "ipconfig"
