如何解析laravel到json，并从android接收它

Question

Hello I would like to know how to connect my Laravel base Web service to My Android Application? Currently im tried with both native and laravel code. and i manage to get the json from native php. but then when I Tried it in Laravel it returns the same json but unable to receive it in Android, the error says something about Doctype

For The Laravel in my Controller

    public function jsonview()
{
    $data2  =DB::table('item_list')->orderBy('id','desc')->get();
    $response = array();
    $response["status"] =1;
    $response["message"] = "getting data";
    $response["data"]=array();
    //$response["data"] = $data2;
    //or with
    foreach ($data2 as $data2) {
        $datas = array();
        //echo "lol";
        $datas["nama_item"] = $data2->nama_item;
        $datas["description"] = $data2->description;
        $datas["price"] = $data2->harga;
        $data = DB::table('users')->where("id","=",$data2->seller)->first();
        $datas["seller"] = $data->firstname;
        $datas["picture"] = $data2->pic_name;
        array_push($response["data"], $datas);
    }
    //dd(Request::json()->get('data'));

    return Response()->json(['data'=>$response["data"]]);
}

This happens probably because your code shows error page. And it is HTML page and of course it contains DOCTYPE at the beginning.

Just check your logs for errors and fix them.
