I am programming to upload my images to my server in a folder but it does not upload and I get the following error:
org.json.JSONException: Value [] of type org.json.JSONArray can not be converted to JSONObject
The times I tried them (I think about 10), 4 entered by OnResponse and the others by onError and from there it always enters by onError and shows me that error that I mention above. I have not modified any code. And just in case, when I entered by onResponse I would not upload any image to my %%% of my server folder. Thank you very much for your help, friends.
Here is my code of ../fotos/.. that would be the webservice that connects me the android with the database.
<?php
$host_name = "localhost";
$database = "base_olx";
$user = "root";
$password = "";
$con = mysqli_connect($host_name,$user,$password,$database);
$json = json_decode(file_get_contents("php://input"),true);
//$nombre = $json["nombre"];
$nombre = "nombreestatico";
$listaImagen = $json["listaImagen"];
$respuesta = array();
if(isset($listaImagen)){
if(is_array($listaImagen)){
foreach($listaImagen as $imagen){
$decodedImagen = base64_decode($imagen);
$return =
file_put_contents("../fotos/".$nombre."_".$i.".JPG",$decodedImagen);
$i++;
$respuesta["ok"] = 1;
}
}
echo json_encode( $respuesta);
}else{
$respuesta["ok"] = 0;
echo json_encode( $respuesta);
}
?>
and here is my code in android studio:
