saludos compañeros estoy intentando hacer un sistema de login desde un dispositivo a mi foro php , el caso es que via navegador la url que paso funciona bien pero desde android me tira errores , este es el código:

Código:

public class MainActivity extends Activity {
	TextView tx;
	EditText user, pass;
	Button but;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		tx = (TextView) findViewById(R.id.textView1);
		user = (EditText) findViewById(R.id.editText1);
		pass = (EditText) findViewById(R.id.editText2);
		but = (Button) findViewById(R.id.button1);
		but.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				connect();

			}
		});

	}

	public void connect() {

		try {
			String us = URLEncoder.encode(user.getText().toString(), "UTF-8");
			String passw = URLEncoder
					.encode(pass.getText().toString(), "UTF-8");
			String url = String
					.format("http://www.mipaginaweb.com/login.php?username=%s&password=%s",
							us, passw);

			postLoginData();

		} catch (UnsupportedEncodingException ex) {
			ex.printStackTrace();
		}

	}

	public void postLoginData() {
		// Create a new HttpClient and Post Header
		HttpClient httpclient = new DefaultHttpClient();

		/* login.php returns true if username and password is equal to saranga */
		HttpPost httppost = new HttpPost(
				"http://www.amsspecialist.com/login.php");

		try {
			// Add user name and password

			String username = user.getText().toString();

			String password = pass.getText().toString();

			List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
			nameValuePairs.add(new BasicNameValuePair("username", username));
			nameValuePairs.add(new BasicNameValuePair("password", password));
			httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

			// Execute HTTP Post Request
			Log.w("SENCIDE", "Execute HTTP Post Request");
			HttpResponse response = httpclient.execute(httppost);

			String str = convertInputStreamToString(
					response.getEntity().getContent()).toString();
			Log.w("SENCIDE", str);

			
			tx.setText(str.toString());
			

		} catch (ClientProtocolException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

	private static String convertInputStreamToString(InputStream inputStream)
			throws IOException {
		BufferedReader bufferedReader = new BufferedReader(
				new InputStreamReader(inputStream));
		String line = "";
		String result = "";
		while ((line = bufferedReader.readLine()) != null)
			result += line;

		inputStream.close();
		return result;

	}
}

y este el logcat con el error

Solo con poner el nombre de la excepción en google (android.os.NetworkOnMainThreadException) te sale la respuesta.

También se ha comentado por aquí alguna vez, el acceso a la red tiene que hacerse desde otro hilo (una AsyncTask por ejemplo) para no bloquear el hilo principal de ejecución de Android y de la app.
