无法为Android中下载的pdf设置正确的内容类型

Question

I cannot open a pdf that i download from the web:

In first activity class i set the intent type like this:

> Intent myIntent = new Intent(getApplicationContext(),SecondClassActivity.class);
myIntent.setType("application/pdf");

I get to the second class activity that has the logic for downloading the pdf from an URL. I set the path to where to be downloaded, i open an url connection and set the contenty type like this:

URLConnection connection = url.openConnection(); connection.setDoOutput(true); connection.setRequestProperty("Content-Type", "application/pdf"); connection.setRequestProperty("Connection", "Keep-Alive"); connection.setRequestProperty("Content-Disposition","attachment; filename=" + filename); connection.setRequestProperty("charset", "UTF-8"); connection.setRequestProperty("User-Agent","Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.0.13) Gecko/2009073021 Firefox/3.0.13"); connection.connect();

But when i read what type of content type i have:

System.out.println("Connection type : " + connection.getContentType()); the answer is: text/html ... :(

And of course i cannot open the pdf with adobe, i get and error saying "Unable to open this file". I think it's because the content type is not correct.

Does anyone got into this error before? I looked at this post but still does not work... Thank you for your time.

您为Intent设置的类型与URLConnection对象中设置的内容类型无关。
