Как отправить массив JSON, содержащий jsonobjects на php-сервер

Вместо этого используйте StringRequest вместо JsonArrayRequest:

 private void register() { 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 = new StringRequest(Request.Method.POST, Config.MAIN_URL + Config.REGISTER, new Response.Listener<String>() { @Override public void onResponse(String response) { Log.d(TAG, "Register Response: " + response.toString()); hideDialog(); try { JSONObject jsonObject = new JSONObject(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(); } } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { Log.e(TAG, "Registration Error: " + error.getMessage()); hideDialog(); Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_LONG).show(); } }) { @Override protected Map<String, String> getParams() { // Posting params to register url Map<String, String> params = new HashMap<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 queue AppController.getInstance().addToRequestQueue(strRequest); } 

Это рабочий код для образца входа. поэтому попробуйте это и измените в соответствии с вашими потребностями.
