I have a php URL, which when I run in a browser, it returns to me a PDF file. In my application I want to download this PDF file. I'm trying to do this:
HttpURLConnection urlConnection = urlConnection = (HttpURLConnection) url_download_relatorio_funcionario.openConnection(); urlConnection.setRequestMethod("GET"); urlConnection.setDoOutput(true); urlConnection.connect(); int totalSizePDF = urlConnection.getContentLength();
But the integer value "totalSizePDF" only returns to me -1 value, instead of the real size of PDF file which is opened if I run this URL in a browser. How can I download this PDF file from the php URL, producing the same effect as a browser?
