You must specify a [ParcelFileDescriptor][2] 68that is seekable (that is, the content can be randomly accessed) on which the 69system writes the the printable content. Your app can obtain a page for 70rendering with [openPage()][3], then call [render()][4] to turn the opened 71[PdfRenderer.Page][5] into a bitmap. 72 73This sample loads the PDF from assets. Contents of assets are compressed by 74default, but we disable it since PdfRenderer class cannot handle it. 75 76```groovy 77android { 78 aaptOptions { 79 noCompress "pdf" 80 } 81} 82``` 83 84[1]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.html 85[2]: https://developer.android.com/reference/android/os/ParcelFileDescriptor.html 86[3]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.html#openPage(int) 87[4]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.Page.html#render(android.graphics.Bitmap, android.graphics.Rect, android.graphics.Matrix, int) 88[5]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.Page.html 89]]> 90 </intro> 91 </metadata> 92 93</sample> 94
