How to download a pdf file in Android?

Question

I want to download a pdf file from an url. For viewing the pdf file I used the code below.

File file = new File("/sdcard/example.pdf");

if (file.exists()) {
    Uri path = Uri.fromFile(file);
    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setDataAndType(path, "application/pdf");
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    try {
        startActivity(intent);
    } 
    catch (ActivityNotFoundException e) {
        Toast.makeText(OpenPdf.this, "No Application Available to View PDF",
            Toast.LENGTH_SHORT).show();
    }
}

It is working but how do I get the pdf file from an url (e.g http://.../example.pdf). I want to download the pdf file from this url. Please help me. Thanks in advance.

Answer 1

Download a pdf:

 startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("www.education.gov.yk.ca/pdf/pdf-test.pdf")));

Ah as I've just found out this is device dependent.

scenarios

1. It will download the pdf to your browser/downloaded/ folder

2. You have a google docs account - It will ask you to sign in then view the pdf in the browser

3. You have a pdf reader installed - App dependent may catch it may not

In all scenarios though the user has access to the PDF with one line of code :-)

Answer 2

Downloading a PDF works the same as downloading any other binary file.

1. Open a HttpUrlConnection
2. Use the connection's getInputStream() method to read the file.
3. Create a FileOutputStream and write the inputstream.

Check this post for example source code.
