You must specify a [ParcelFileDescriptor][2] 65that is seekable (that is, the content can be randomly accessed) on which the 66system writes the the printable content. Your app can obtain a page for 67rendering with [openPage()][3], then call [render()][4] to turn the opened 68[PdfRenderer.Page][5] into a bitmap. 69 70This sample loads the PDF from assets. Contents of assets are compressed by 71default, and the PdfRenderer class cannot open it. In this sample, we work 72around this by copying the file into the cache directory. 73 74[1]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.html 75[2]: https://developer.android.com/reference/android/os/ParcelFileDescriptor.html 76[3]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.html#openPage(int) 77[4]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.Page.html#render(android.graphics.Bitmap,%20android.graphics.Rect,%20android.graphics.Matrix,%20int) 78[5]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.Page.html 79 80]]> 81 </intro> 82 </metadata> 83 84</sample> 85
