And here is my code:
public void executeHttpGet(String cis) throws Exception {
BufferedReader in = null;
try {
HttpClient client = new DefaultHttpClient();
Toast.makeText(this, "http://www.**************.net/******/test.php?ci=" + cis, 2).show();
HttpGet request = new HttpGet(http://www.**************.net/******/test.php?ci=" + cis);
//request.setURI(new URI("http://w3mentor.com/"));
HttpResponse response = client.execute(request);
in = new BufferedReader
(new InputStreamReader(response.getEntity().getContent()));
StringBuffer sb = new StringBuffer("");
String line = "";
String NL = System.getProperty("line.separator");
while ((line = in.readLine()) != null) {
sb.append(line + NL);
}
in.close();
String page = sb.toString();
System.out.println(page);
} finally {
if (in != null) {
try {
in.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
What im doing wrong?
Thanks and have a nice day!
Don’t forget to add internet permission in your AndroidManifest.xml file.
