I try to connect with WiFi module, but i have unfortunately error. It is in 102 line that is:
HttpResponse response = httpclient.execute(getRequest); // execute the request
Here is my all code:
public class WiFi extends ListActivity implements View.OnClickListener {
public final static String PREF_IP = WiFiComuncation.PREF_IP;
public final static String PREF_PORT = WiFiComuncation.PREF_PORT;
SharedPreferences.Editor editor;
SharedPreferences sharedPreferences;
public static final String RESPONSE = "Response";
private String serverResponse = "ERROR"; // Ustawiam na domyslny blad problemu z polaczeniem z modułem WiFI
private String ipAddress, portNumber;
private String parameterValue;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ipAddress=PREF_IP;
portNumber=PREF_PORT;
sharedPreferences = getSharedPreferences("HTTP_HELPER_PREFS", Context.MODE_PRIVATE);
editor = sharedPreferences.edit();
editor.putString(PREF_IP, "192.168.4.1"); // set the ip address value to save
editor.putString(PREF_PORT, "80"); // set the port number to save
editor.commit(); // save the IP and PORT
serverResponse = sendRequest(parameterValue,ipAddress,portNumber); // wysyłam zapytanie do mikrokloca
Intent intent = getIntent();
parameterValue = intent.getStringExtra("parameterValue");
checkAnswer(serverResponse);
prepareResponse();
finish();
}
private void prepareResponse() { // Zwracam odpowiedz
String response = serverResponse;
Intent resultIntent = new Intent();
resultIntent.putExtra(RESPONSE, response);
setResult(RESULT_OK, resultIntent);
}
private boolean checkAnswer( String response )
{
if(response.equals("E001")) // problem z polaczeniem z WiFi
{
Toast.makeText(getApplicationContext(), "#E001 - Błąd połączenia urządzenia z modułem WiFi! ", Toast.LENGTH_LONG).show(); // Wyswitlanie komunikatu na apce
return false;
}
if(response.equals("E002")) // Błędny odcisk palca
{
Toast.makeText(getApplicationContext(), "#E002 - Błędny odcisk palca! ", Toast.LENGTH_LONG).show(); // Wyswitlanie komunikatu na apce
return false;
}
if(response.equals("E003")) //Błąd komunikacji pomiędzy podzespołami
{
Toast.makeText(getApplicationContext(), "#E001 - Błąd komunikacji pomiędzy podzespołami! ", Toast.LENGTH_LONG).show(); // Wyswitlanie komunikatu na apce
return false;
}
else
{
return true;
}
}
