ANDROID&PHP - Why am I getting this JSONArray parsing error
Question
I've tried various methods to display data from MySQL into android with PHP and JSON from my hosting here , but always getting error like this
but when i request another link with the same JSON result, its work fine
i've tried to find out, and i suggested to enable JavaScript in my hosting, but i didn't find out the reference how to enable JavaScript in my hosting,
here is the PHP code to encode_JSON
<?php
include 'dbconfig.php';
$con = new mysqli($servername, $username, $password, $dbname);
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$query = "select id,ask from pertanyaan";
$result = mysqli_query($con, $query);
$rows = array();
while ($r = mysqli_fetch_array($result)) {
$rows[] = $r;
}
echo json_encode(array_values($rows));
mysqli_close($con);
?>
did i using wrong code to encode_json from PHP?
EDITED AFTER ADD header('Content-Type: application/json');

Compared given two request. You haven't set the header in PHP script as JSON. For setting Content-type header as JSON, put following code in PHP script
header('Content-Type: application/json');
It will work. There is not error in your android code, as the 2nd url gives the desired result. Also I don't think there is any problem while encoding JSON.
While comparing two links check the Content-type header in request, both are different.

You can try this.
<?php
include 'dbconfig.php';
$con = new mysqli($servername, $username, $password, $dbname);
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$query = "select id,ask from pertanyaan";
$result = mysqli_query($con, $query);
while ($r = mysqli_fetch_array($result)) {
extract($r);
$rows[] = array(
"id"=>$id,
"ask"=>$ask
);
}
header('Content-Type: application/json');
echo json_encode($rows);
mysqli_close($con);
?>
