Question

I am making a system in webview where user can change their image.

using ajax , laravel , webview but it's not working showing following error . profile_picture}}" alt="" width="100" height="100" id="user_profile_img"> {{$user->name}} Web Developer · Designer · Team Lead
Upload profile Picture Save

<script type="text/javascript">

    $("#save_user_profile").click(function (event) {
        event.preventDefault();
        var authorizationToken = $("#authtoken").val();
        var form = document.forms.namedItem("user_profile_form"); // high importance!, here you need change "yourformname" with
        var formData = new FormData(form);


        $.ajax({
            headers: {
                'Authorization': authorizationToken,
                'device_type': 'android'
            },
            async: true,
            type: 'post',
            contentType: false,
            cache: false,

            url: '{{ action('Mobile\UserProfileController@updateUserProfile') }}',
            data: formData,
            processData: false,
            success: function (data) {
                var result = JSON.parse(data);

                if (result.status) {
                    alert(result.message);
                } else {
                    alert(result.message);
                }
            },
            error: function (jqXHR, textStatus, errorThrown) {
                alert(errorThrown);
            }
        });
    });


    Android.pageParams("Profile", "", "", false, "", "", "");
</script>

this is my controller

public function updateUserProfile(Request $request)
    {

        $userimg = $request->file('user_profile_picture');
        echo json_encode(['status' => true, 'message' => $_FILES]);
    }

Getting following error :

{"status":true,"message":{"user_profile_picture":{"name":"","type":"","tmp_name":"","error":4,"size":0}}}

pls keep in mind that I am not using it in browser it opening in android webvier or ios webview or any other , but this will be in webview
