Question

RegisterActivity.java

public class RegisterActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_register);

    final EditText etname = (EditText) findViewById(R.id.reg_name);
    final EditText etage = (EditText) findViewById(R.id.reg_age);
    final EditText etusername = (EditText) findViewById(R.id.reg_username);
    final EditText etpass = (EditText) findViewById(R.id.reg_pass);
    Button reg_btn = (Button) findViewById(R.id.btn_reg);

    reg_btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            String name = etname.getText().toString();
            int age = Integer.parseInt(etage.getText().toString());
            String username = etusername.getText().toString();
            String password = etpass.getText().toString();

            Response.Listener<String> responselistener = new Response.Listener<String>() {
                @Override
                /*reponse from register.php*/
                public void onResponse(String response) {
                    try {
                        JSONObject jsonResponse = new JSONObject(response);
                        boolean success = jsonResponse.getBoolean("success");

                        if(success){
                            Toast.makeText(RegisterActivity.this, "Registration successful!", Toast.LENGTH_LONG).show();
                            Intent i = new Intent(RegisterActivity.this, LoginActivity.class);
                            RegisterActivity.this.startActivity(i);
                        }else{
                            /* Memunculkan dialog box berisi kata "Register Failed" dan tombol "Retry" agar
                               pengguna dapat mencoba mendaftar kembali
                             */
                            AlertDialog.Builder builder = new AlertDialog.Builder(RegisterActivity.this);
                            builder.setMessage("Register Failed").setNegativeButton("Retry", null).create().show();
                        }

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

                }
            };

            RegisterRequest registerRequest = new RegisterRequest(name, age, username, password, responselistener);
            RequestQueue queue = Volley.newRequestQueue(RegisterActivity.this);
            queue.add(registerRequest);
        }
    });
}
}

RegisterRequest.java

public class RegisterRequest extends StringRequest {
        private static String REGISTER_REQUEST_URL = "http://tesapp.000webhostapp.com/Register.php";
private Map<String, String> params;

public RegisterRequest(String name, int age, String username, String password, Response.Listener<String> listener){
    /* Method.POST untuk mengirim data ke register.php dan register.php akan merespon data tersebut */
    super(Method.POST, REGISTER_REQUEST_URL, listener, null);
    params = new HashMap<>();
    params.put("name", name);
    params.put("age", age + "");
    params.put("username", username);
    params.put("password", password);
}

@Override
public Map<String, String> getParams() {
    return params;
}
}

Register.php

<?php
$con = mysqli_connect("localhost", "id406711_apmob", "animasi", "id406711_userdata");

$name = $_POST["name"];
$age = $_POST["age"];
$username = $_POST["username"];
$password = $_POST["password"];
$statement = mysqli_prepare($con, "INSERT INTO user (name, age, username, password) VALUES (?, ?, ?, ?)");
mysqli_stmt_bind_param($statement, "siss", $name, $age, $username, $password);
mysqli_stmt_execute($statement);

$response = array();
$response["success"] = true;  

echo json_encode($response);
?>

当我运行应用程序时，我收到了这个错误：
