1 Android PdfRendererBasic Sample 2 =================================== 3 4 This sample demonstrates how to display PDF document on screen using 5 the PdfRenderer introduced in Android 5.0 Lollipop. 6 7 Introduction 8 ------------ 9 10 You can now render PDF document pages into bitmap images for printing by using 11 the new [PdfRenderer][1] class. You must specify a [ParcelFileDescriptor][2] 12 that is seekable (that is, the content can be randomly accessed) on which the 13 system writes the the printable content. Your app can obtain a page for 14 rendering with [openPage()][3], then call [render()][4] to turn the opened 15 [PdfRenderer.Page][5] into a bitmap. 16 17 This sample loads the PDF from assets. Contents of assets are compressed by 18 default, but we disable it since PdfRenderer class cannot handle it. 19 20 ```groovy 21 android { 22 aaptOptions { 23 noCompress "pdf" 24 } 25 } 26 ``` 27 28 [1]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.html 29 [2]: https://developer.android.com/reference/android/os/ParcelFileDescriptor.html 30 [3]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.html#openPage(int) 31 [4]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.Page.html#render(android.graphics.Bitmap, android.graphics.Rect, android.graphics.Matrix, int) 32 [5]: https://developer.android.com/reference/android/graphics/pdf/PdfRenderer.Page.html 33 34 Pre-requisites 35 -------------- 36 37 - Android SDK v21 38 - Android Build Tools v21.1.1 39 - Android Support Repository 40 41 Screenshots 42 ------------- 43 44 <img src="screenshots/main.png" height="400" alt="Screenshot"/> 45 46 Getting Started 47 --------------- 48 49 This sample uses the Gradle build system.
