I am trying to get json Array from url in android using volley but it is showing following error
com.android.volley.ParseError: org.json.JSONException: Value of type java.lang.String cannot be converted to JSONArray
that means i am receiving html from url.
how can i receive data in json format from url so that i can parse using jsonObject or jsonArray in android
My android code is
RequestQueue queue = Volley.newRequestQueue(getContext());
JsonArrayRequest request = new JsonArrayRequest(Method.GET, URL,null, new Response.Listener<JSONArray>() {
@Override
public void onResponse(JSONArray response ) {
Toast.makeText(getContext(), response, Toast.LENGTH_SHORT).show();
Log.i("My success",""+response.toString());
try {
for (int i = 0; i <= response.length(); i++) {
JSONObject silver_rate_values = response.getJSONObject(i);
String Silver_Rate = silver_rate_values.getString("silver_rate");
Log.v("SilverRate", "silverRate value is" + Silver_Rate);
}
}catch (JSONException e) {
e.printStackTrace();
Log.e("Silver rate", "Json parsing error: " + e.getMessage());
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getContext(), "my error :"+error, Toast.LENGTH_LONG).show();
Log.i("My error",""+error);
}
}){
};
My php code is
$sql = "SELECT * FROM `user_info`
"
. "ORDER BY `customer_info`.`updatedTime` DESC LIMIT 1";
$result = mysqli_query( $con,$sql );
if(! $result ) {
die('Could not get data: ' . mysql_error());
}
//print values to screen
$data = array();
while ($row = mysqli_fetch_assoc($result)) {
$a = $row['a'];
$b = $row['b'];
$c = $row['c'];
$data[] = $row;
}
header('Content-type: application/json');
$json=json_encode(array("Values" => $data));
echo $json;
?>
</body>
My php output is
<html>
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
{"Values":[{"a":"8888","b":"9999","c"7777"}]} </body>
</html>
If I remove header from php code then the output is
{"Values":[{"a":"8888","b":"9999","c"7777"}]}
Then also I am getting same error from Android side
