title: Cannot access pdf file from raw resources
body: <p>I created an android pdf reader using MuPdf library. My problem is when I change the uri to access the pdf file from the raw resources, <strong><code>Uri uri = Uri.parse("android.resource/[package]/" + R.raw.[pdf])</code></strong>, i get a <code>java.lang.RuntimeException</code> error. But when i change the uri to access the pdf file from the sd card,  <strong><code>Uri uri = Uri.parse("file:///sdcard/[pdf]")</code></strong> , i will have no error and it reads and displays the pdf file successfully. My main goal is to read and display a pdf file from the resources, not from the sd card. Do you have any idea on how to solve this?</p>
