I am writing an Android program that needs to access a URL with GET variables which will be logged into a database. All I need to do is open a URL so the web server will log the data! How should I go about this?
Thanks

1Here's an excellent 3rd party Android Asynchronous Http Client loopj.com/android-async-http If you don't need AsyncTask at all, just go with Apache's HttpClienthovanessyan– hovanessyan2013-04-15 05:52:12 +00:00Commented Apr 15, 2013 at 5:52

// default HTTP Client
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
try {
HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

Use this.
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("URL HERE"));
startActivity(browserIntent);
Hope this helps.
EDIT:
Ok, use this. It calls the URL without opening a browser
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpGet httpGet = new HttpGet("URL HERE");
HttpResponse response = httpClient.execute(httpGet, localContext);

Do you just want to hide browser?

No I don't want to hide it, I just need to access the URL. I don't need to see the web page because the server doesn't return any data.
You can also use HttpUrlConnection. Sample code -
// Given a URL, establishes an HttpUrlConnection and retrieves
// the web page content as a InputStream, which it returns as
// a string.
private String downloadUrl(String myurl) throws IOException {
InputStream is = null;
// Only display the first 500 characters of the retrieved
// web page content.
int len = 500;
try {
URL url = new URL(myurl);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(10000 /* milliseconds */);
conn.setConnectTimeout(15000 /* milliseconds */);
conn.setRequestMethod("GET");
conn.setDoInput(true);
// Starts the query
conn.connect();
int response = conn.getResponseCode();
Log.d(DEBUG_TAG, "The response is: " + response);
is = conn.getInputStream();
// Convert the InputStream into a string
String contentAsString = readIt(is, len);
return contentAsString;
// Makes sure that the InputStream is closed after the app is
// finished using it.
} finally {
if (is != null) {
is.close();
}
}
}
// Reads an InputStream and converts it to a String.
public String readIt(InputStream stream, int len) throws IOException, UnsupportedEncodingException {
Reader reader = null;
reader = new InputStreamReader(stream, "UTF-8");
char[] buffer = new char[len];
reader.read(buffer);
return new String(buffer);
}
And obviously since it is a netowork call you cannot do it in main/UI thread. So you can do it in async task. More details and Source
