I am developing an app for android and now I am doing the user "CreateAccount" and "Login" activities. I am able to insert the user's info in the database, but I am not able to get the user's info from the database to perform the login. This is my java code:
String showUrl = "http://192.168.0.11/webapps/showUser.php";
public void searchLoginInfo(View view) {
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST,showUrl,null, new Response.Listener<JSONObject>()
{
@Override
public void onResponse(JSONObject response) {
try {
JSONArray users = response.getJSONArray("users");
for (int i = 0; i < users.length(); i++) {
JSONObject user = users.getJSONObject(i);
String username = user.getString("username").toLowerCase();
String password = user.getString("password").toLowerCase();
String retypedPassword = user.getString("retypedpassword").toLowerCase();
String email = user.getString("passphrase").toLowerCase();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener()
{
@Override
public void onErrorResponse(VolleyError error) {
Log.e(TAG, "onErrorResponse: ERORR!!!!!!!!!!!" );
Log.e(TAG, "onErrorResponse: ERORR!!!!!!!!!!!"+error.toString() );
}
});
requestQueue.add(jsonObjectRequest);
}
The error that I get is: E/MyActivity: onErrorResponse: ERORR!!!!!!!!!!! E/MyActivity: onErrorResponse: ERORR!!!!!!!!!!!com.android.volley.ParseError: org.json.JSONException: Value Connection of type java.lang.String cannot be converted to JSONObject. This is my showUser.php script :
<?php
if($_SERVER["REQUEST_METHOD"]=="POST"){
include 'connection.php';
showUser();
}
function showUser(){
global $connect;
$query="SELECT* FROM user;";
$result=mysqli_query($connect,$query);
$number_of_rows=mysqli_num_rows($result);
$temp_array=array();
if($number_of_rows>0){
while($row=mysqli_fetch_assoc($result)){
$temp_array[]=$row;
}
}
header('Content-Type:application/json');
echo json_encode(array("users"=>$temp_array));
mysqli_close($connect);
}
?>
From what I have red on the internet there could be a problem with the collation?! My table collation and columns is utfmb4_general_ci and my server connection collation is utfmb4_unicode_ci PrintScreen
I have also used POSTMAN to see the actual response from the server and it looks OK to me.
{
"users": [
{
"username": "charlie",
"password": "harris",
"retypedpassword": "harris",
"email": "charlie@yahoo.com"
},
{
"username": "tomas",
"password": "kovtun",
"retypedpassword": "kovtun",
"email": "tkovtu@yahoo.com"
}
]
}
This problem is really killing me guys so any help will be appreciated! Thx!
