Android Studio MySql Connection

Question

Я пытаюсь подключить Android Studio к базе данных MySQL на сервере WAMP.База данных настроена и называется happyplanet.Соединение через php работает, но на стороне andorid есть некоторые ошибки.

У меня есть класс статуса проверки сети:

import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;

public class CheckNetworkStatus {


        public static boolean isNetworkAvailable(Context context) {
            ConnectivityManager connectivityManager
                    = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
            return activeNetworkInfo != null && activeNetworkInfo.isConnected();
        }



}

Моя основная деятельность:

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
//      add new product button
        Button addNewBtn = (Button) findViewById(R.id.addNewBtn);

        addNewBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //Check for network connectivity
                if (CheckNetworkStatus.isNetworkAvailable(getApplicationContext())) {
                    Intent i = new Intent(getApplicationContext(),
                            AddProductActivity.class);
                    startActivity(i);
                } else {
                    //Display error message if not connected to internet
                    Toast.makeText(MainActivity.this,
                            "Unable to connect to internet",
                            Toast.LENGTH_LONG).show();

                }

            }

Всякий раз, когда я запускаю свое приложение, выводится сообщение «при добавлении фильма произошла ошибка».Я изменил манифесты и просто не могу найти свою ошибку.

Любая помощь будет очень признательна!Я знаю, что это много читать, но я действительно застрял: /
