How To Send Json Array Containg Jsonobjects To Php Server

Hello everyone I m sorry if this has been asked earlier , i have been searching for this solution since past 3 days.I am new in android and php. I want to know how can i send 'json

Solution 1:

Use StringRequest instead of JsonArrayRequest for example:

privatevoidregister() {

        if (!validate()) {

            onRegistrationFailed("Registration Failed");
            return;

        }
        final String name = et_username.getText().toString();
        final String email = et_email.getText().toString();
        final String phone = et_phone.getText().toString();
        final String password = et_password.getText().toString();

        showDialog();

        StringRequest strRequest = newStringRequest(Request.Method.POST, Config.MAIN_URL + Config.REGISTER,
                newResponse.Listener<String>() {
                    @OverridepublicvoidonResponse(String response) {
                        Log.d(TAG, "Register Response: " + response.toString());
                        hideDialog();
                        try {
                            JSONObject jsonObject = newJSONObject(response);

                            int status = jsonObject.getInt("status");
                            String msg = jsonObject.getString("message");

                            if (status == SUCCESS) {

                                onRegistrationSuccess(name,email);

                            } else {

                                onRegistrationFailed(msg);
                            }

                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }

                }, newResponse.ErrorListener() {
            @OverridepublicvoidonErrorResponse(VolleyError error) {
                Log.e(TAG, "Registration Error: " + error.getMessage());
                hideDialog();
                Toast.makeText(getApplicationContext(),
                        error.getMessage(), Toast.LENGTH_LONG).show();
            }
        }) {
            @OverrideprotectedMap<String, String> getParams() {
                // Posting params to register urlMap<String, String> params = newHashMap<String, String>();
                params.put(Config.KEY_USERNAME, name);
                params.put(Config.KEY_EMAIL, email);
                params.put(Config.KEY_PHONE, phone);
                params.put(Config.KEY_PASSWORD, password);
                return params;
            }

        };

        // Adding request to request queueAppController.getInstance().addToRequestQueue(strRequest);

    }
