Cant seem to figure out whats wrong in this android program! Help Me : I am getting errorResponse instead of the normal response i should have got. I have made a simple php file with a simple text and put it on the wamp server. And i have checked it on the browser it works fine but not in this code. 




  public class MainActivity extends AppCompatActivity {
    
    
        Button button;
        TextView textView;
        String server_url="http://192.168.1.2/greetings.php";
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
    
            button= (Button) findViewById(R.id.bn);
            textView= (TextView) findViewById(R.id.txt);
    
    
            final RequestQueue requestQueue= Volley.newRequestQueue(MainActivity.this);
    
            button.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
    
    
    
                    StringRequest stringRequest=new StringRequest(Request.Method.POST, server_url, new Response.Listener<String>() {
                        @Override
                        public void onResponse(String response) {
    
                            textView.setText(response);
                            requestQueue.stop();
    
                        }
                    }, new Response.ErrorListener() {
                        @Override
                        public void onErrorResponse(VolleyError error) {
    
                            textView.setText("something wrong happened");
                            error.printStackTrace();
                            requestQueue.stop();
    
                        }
                    });
    
                    requestQueue.add(stringRequest);
    
                }
            });
    
    
    
    
        }
    }
