2Android PdfRendererBasic Sample
3===================================

5This sample demonstrates how to display PDF document on screen using
6the PdfRenderer introduced in Android 5.0 Lollipop.

8Introduction
9------------
10
11You can now render PDF document pages into bitmap images for printing by using
12the new [PdfRenderer][1] class. You must specify a [ParcelFileDescriptor][2]
13that is seekable (that is, the content can be randomly accessed) on which the
14system writes the the printable content. Your app can obtain a page for
15rendering with [openPage()][3], then call [render()][4] to turn the opened
16[PdfRenderer.Page][5] into a bitmap.
17
18This sample loads the PDF from assets. Contents of assets are compressed by
19default, but we disable it since PdfRenderer class cannot handle it.

21```groovy
22android {
23    aaptOptions {
24        noCompress "pdf"
25    }
26}
