I have a very, very simple app. I've set it up using xampp. When I attempt to log a user into the localhost nothing happens, at all. No error, no logcat, nothing... very strange. I have tested XAMPP, it loads php pages into my browser, runs etc. XAMPP is definitely working as my localhost. I have tested the java
class on an actual URL and it works. Here's the code:
connect.php
<?php
$host = 'localhost';
$user = 'root';
$pass = '';
$db = 'test';
$conn_error = 'Not Connected!';
if (!mysql_connect($host, $user, $pass) || !mysql_select_db($db)) {
die ($conn_error);
}
?>
test.php
<?php
require_once 'connect.php';
$username = $_POST['username'];
$password = $_POST['password'];
$query_search = "SELECT * FROM members WHERE username = '".$username."' AND password = '".$password. "'";
$query_exec = mysql_query($query_search) or die(mysql_error());
$rows = mysql_num_rows($query_exec);
if($rows == 1) {
echo "1";
} else {
echo "Username/Password is invalid";
}
?>
login.java
class LogMeIn extends AsyncTask<String, Void, String> {
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://localhost/test.php");
protected String doInBackground(String... urls) {
try {
username = un.getText().toString();
password = pw.getText().toString();
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(
2);
nameValuePairs
.add(new BasicNameValuePair("username", username));
nameValuePairs
.add(new BasicNameValuePair("password", password));
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = client.execute(post);
String res = inputStream(response.getEntity().getContent())
.toString();
Log.v("RESPONSE", res);
// if username and password are valid, launch main activity
if (res.toString() == "1") {
Intent logIn = new Intent(getApplicationContext(),
Main.class);
startActivity(logIn);
}
I think it's my URL for the post. localhost/test.php
. However I have tried the following
None of them work. Probably a very simple solution and almost certainly a duplicate question but I cannot for the life of me figure this out.
EDIT
I changed the localhost to http://192.168.x.x/test.php and at first nothing... then finally I got a warning in logcat, like a caught exception. It says

Are you testing it with the emulator or your actual device?
If Device: Pointing it to localhost is going to make the android device think it's sitting on the local server. So will 127.0.0.1. If the device is connected to to the same network as your XAMPP server, you have to point it to the server's internal IP. If not connected, you'll have to allow outside connections to get to that machine then point to the external IP.
10.0.2.2 will only work if you are testing the app on an emulator. You can read more about it here.
I would like to tell my analysis :D
I think your problem lies in this code :
String res = inputStream(response.getEntity().getContent()).toString();
Because you cannot directly turn an inputstream into a String by using .toString()
method.
To convert inputStream into string, here's a little snippet :
public static String responseToString(HttpResponse response){
String result = "";
try{
InputStream in = response.getEntity().getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
StringBuilder str = new StringBuilder();
String line = null;
while((line = reader.readLine()) != null){
str.append(line + "
");
}
in.close();
result = str.toString();
}catch(Exception ex){
result = "Error";
}
return result;
}
Then modify your code below HttpResponse response = client.execute(post);
into this :
HttpResponse response = client.execute(post);
String res = responseToString(response); // add .trim().replace("
", "") if you have newlines
I hope this is helpful, Good Luck!! ^^
