Android - Eclipse - What does docUri mean?

Question

I am working through this tutorial https://developers.google.com/cloud-print/docs/android for google cloud print. I am trying to add a print functionality to my application. However I have NO IDEA what docUri stands for/means/definition. I am trying to print the file "/sdcard/StudentLatePass.txt"

This is what I have so far,

public void onClick(View v) {
            //Print using Google Cloud Print
            Intent printIntent = new Intent(StudentActivity.this, PrintDialogActivity.class);
                printIntent.setDataAndType(docUri, "text/plain");
                printIntent.putExtra("title", "Student Late Pass");
                startActivity(printIntent);

            }// onClick
    });// btnPrintSDFile

Answer 1

docUri - URI of the document to be printed.

What is a URI? A uniform resource identifier (URI) is a string of characters used to identify a name or a resource (Wiki URI).

I think that you can set it using:

printIntent.setDataAndType(Uri.fromFile(new File("/sdcard/StudentLatePass.txt")), "text/plain");

Answer 2

Did you read the documentation? It's the URI of the doc you want to print.

http://developer.android.com/reference/android/content/Intent.html#setDataAndType(android.net.Uri, java.lang.String)

It even says so in the example:

In the code above, replace the three parameters as follows:

docUri - URI of the document to be printed

docMimeType - MIME type of the document to be printed. We recommend that you use PDF (application/pdf) format

docTitle - title of the printed document, arbitrary string that will be shown on the GCP management console as the print job's title

Answer 3

docUri here is the Uri of the document you want to print.

String location ="/sdcard/StudentLatePass.txt";
File f = new File(location);
        Uri docUri =Uri.fromFile(f);
