     70 You can now render PDF document pages into bitmap images for printing by using
     71 the new [PdfRenderer][1] class. You must specify a [ParcelFileDescriptor][2]
     72 that is seekable (that is, the content can be randomly accessed) on which the
     73 system writes the the printable content. Your app can obtain a page for
     74 rendering with [openPage()][3], then call [render()][4] to turn the opened
     75 [PdfRenderer.Page][5] into a bitmap.
     76 
     77 This sample loads the PDF from assets. Contents of assets are compressed by
     78 default, but we disable it since PdfRenderer class cannot handle it.

     80 ```groovy
     81 android {
     82     aaptOptions {
     83         noCompress "pdf"
     84     }
     85 }
