Проблема возникает при попытке подключения к серверу apache с использованием volley или httpURLConnection. Я использую сервер digitalocean ubuntu, работающий под LAMP, но это не должно иметь значения, потому что приложение даже не подключается к серверу.

Я пробовал:

  • удаление и повторная установка приложение
  • добавление <uses-permission android:name="android.permission.INTERNET " /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> к файлу манифеста
  • добавление android:usesCleartextTraffic="true" к файлу манифеста
  • с использованием встроенного эмулятора студии android и моего телефона (Google Pixel 4 XL)
  • пробует различные способы подключения к серверу, как показано ниже

Первый способ, которым я попытался использовать залп: 

StringRequest stringRequest = new StringRequest(Request.Method.POST, URL,
            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, "Registration Successful", Toast.LENGTH_SHORT).show();
                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                        Toast.makeText(RegisterActivity.this, "Registration Error! Error inserting values to db" + e.toString(), Toast.LENGTH_SHORT).show();
                        loading.setVisibility(View.GONE);
                        registerButton.setVisibility(View.VISIBLE);
                    }
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    error.printStackTrace();
                    Toast.makeText(RegisterActivity.this, "Registration Error! error connecting to db " + error.toString(), Toast.LENGTH_SHORT).show();
                    error.printStackTrace();
                    loading.setVisibility(View.GONE);
                    registerButton.setVisibility(View.VISIBLE);
                }
            })
    {
        @Override
        protected Map<String, String> getParams() throws AuthFailureError {
            Map<String,String> params = new HashMap<>();
            params.put("name",name);
            params.put("emailAddress",emailAddress);
            params.put("password",password);
            params.put("postalAddress",postalAddress);
            params.put("phoneNumber",phoneNumber);
            params.put("bloodType",bloodType);

            return params;
        }
    };

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

}

Второй способ с использованием httpURLConnection: 

//make button invisible and make loading widget visible
    loading.setVisibility(View.VISIBLE);
    registerButton.setVisibility(View.GONE);

    //get inputs and convert to strings
    final String name = this.nameInput.getText().toString().trim();
    final String emailAddress = this.emailAddressInput.getText().toString().trim();
    final String password = this.passwordInput.getText().toString().trim();
   // final String confirmPassword = this.confirmPasswordInput.getText().toString().trim();
    final String postalAddress = this.addressInput.getText().toString().trim();
    final String phoneNumber = this.nameInput.getText().toString().trim();
   // final int phoneNumber = Integer.parseInt(this.nameInput.getText().toString().trim());
    final String bloodType = bloodTypeInput.getSelectedItem().toString().trim();


    class RegisterClass extends AsyncTask<String,Void,String>{

        @Override
        protected void onPreExecute()
        {
            super.onPreExecute();
        }
        @Override
        protected void onPostExecute(String httpResponseMsg)
        {

        }
        @Override
        protected String doInBackground(String... params) {
            hashMap.put("name",params[0]);
            hashMap.put("emailAddress",params[1]);
            hashMap.put("password",params[2]);
            hashMap.put("postalAddress",params[3]);
            hashMap.put("phoneNumber",params[4]);
            hashMap.put("bloodType",params[5]);

            String finalResult = httpParse.postRequest(hashMap,URL);

            return finalResult;
        }
    }

    RegisterClass registerClass = new RegisterClass();

    registerClass.execute(name,emailAddress,password,postalAddress,phoneNumber,bloodType);
