AndroidPdfViewer 1.x is available on AndroidPdfViewerV1 repo, where can be developed independently. Version 1.x uses different engine for drawing document on canvas, so if you don't like 2.x version, try 1.x.
Library for displaying PDF documents on Android, with animations, gestures, zoom and double tap support.
It is based on PdfiumAndroid for decoding PDF files. Works on API 11 and higher.

- Add mechanism for providing documents from different sources - more info here
- Update PdfiumAndroid to 1.5.0
- Thanks to document sources and PdfiumAndroid update, in-memory documents are supported
- Fix not working OnClickListener on PDFView
- com.github.barteksc.exception.FileNotFoundException is deprecated and all usages was removed. All exceptions are delivered to old Configurator#onError() listener.
Configurator#defaultPage(int)andPDFView#jumpTo(int)now require page index (i.e. starting from 0)OnPageChangeListener#onPageChanged(int, int)is called with page index (i.e. starting from 0)- removed scrollbar
- added scroll handle as a replacement for scrollbar, use with
Configurator#scrollHandle() - added
OnPageScrollListenerlistener due to continuous scroll, register withConfigurator#onPageScroll() - default scroll direction is vertical, so
Configurator#swipeVertical()was changed toConfigurator#swipeHorizontal() - removed minimap and mask configuration
Add to build.gradle:
compile 'com.github.barteksc:android-pdf-viewer:2.3.0'
Library is available in jcenter repository, probably it'll be in Maven Central soon.

Scroll handle is replacement for ScrollBar from 1.x branch.
From version 2.1.0 putting PDFView in RelativeLayout to use ScrollHandle is not required, you can use any layout.
To use scroll handle just register it using method Configurator#scrollHandle().
This method accepts implementations of ScrollHandle interface.
There is default implementation shipped with AndroidPdfViewer, and you can use it with
.scrollHandle(new DefaultScrollHandle(this)).
DefaultScrollHandle is placed on the right (when scrolling vertically) or on the bottom (when scrolling horizontally).
By using constructor with second argument (new DefaultScrollHandle(this, true)), handle can be placed left or top.
You can also create custom scroll handles, just implement ScrollHandle interface. All methods are documented as Javadoc comments on interface source.
Version 2.3.0 introduced document sources, which are just providers for PDF documents. Every provider implements DocumentSource interface. Predefined providers are available in com.github.barteksc.pdfviewer.source package and can be used as samples for creating custom ones.
Predefined providers can be used with shorthand methods:
pdfView.fromUri(Uri)
pdfView.fromFile(File)
pdfView.fromBytes(byte[])
pdfView.fromStream(InputStream)
pdfView.fromAsset(String)
Custom providers may be used with pdfView.fromSource(DocumentSource) method.
By default, generated bitmaps are compressed with RGB_565 format to reduce memory consumption.
Rendering with ARGB_8888 can be forced by using pdfView.useBestQuality(true) method.
There are three zoom levels: min (default 1), mid (default 1.75) and max (default 3). On first double tap, view is zoomed to mid level, on second to max level, and on third returns to min level. If you are between mid and max levels, double tapping causes zooming to max and so on.
Zoom levels can be changed using following methods:
void setMinZoom(float zoom);
void setMidZoom(float zoom);
void setMaxZoom(float zoom);Android PdfViewer depends on PdfiumAndroid, which is set of native libraries (almost 16 MB) for many architectures. Apk must contain all this libraries to run on every device available on market. Fortunately, Google Play allows us to upload multiple apks, e.g. one per every architecture. There is good article on automatically splitting your application into multiple apks, available here. Most important section is Improving multiple APKs creation and versionCode handling with APK Splits, but whole article is worth reading. You only need to do this in your application, no need for forking PdfiumAndroid or so.
If you have any suggestions on making this lib better, write me, create issue or write some code and send pull request.
