You must specify a [ParcelFileDescriptor][2] 64 that is seekable (that is, the content can be randomly accessed) on which the 65 system writes the the printable content. Your app can obtain a page for 66 rendering with [openPage()][3], then call [render()][4] to turn the opened 67 [PdfRenderer.Page][5] into a bitmap. 68 69 This sample loads the PDF from assets. Contents of assets are compressed by 70 default, and the PdfRenderer class cannot open it. In this sample, we work 71 around this by copying the file into the cache directory. 72 73 [1]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.html 74 [2]: https://developer.android.com/reference/android/os/ParcelFileDescriptor.html 75 [3]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.html#openPage(int) 76 [4]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.Page.html#render(android.graphics.Bitmap,%20android.graphics.Rect,%20android.graphics.Matrix,%20int) 77 [5]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.Page.html 78 79 ]]> 80 </intro> 81 </metadata> 82 83 </sample> 84
