Now we have this awesome library for PDF viewing:

https://github.com/JoanZapata/android-pdfview

It is really simple to use and has a lot of features:

Android PDFView is a library which provides a fast PDFView component for Android, with animations, gestures, and zoom. It's based on VuDroid for decoding the PDF file.

Just include the view in your XML and use it as follows:

pdfView.fromAsset(pdfName)
    .pages(0, 2, 1, 3, 3, 3)
    .defaultPage(1)
    .showMinimap(false)
    .enableSwipe(true)
    .onDraw(onDrawListener)
    .onLoad(onLoadCompleteListener)
    .onPageChange(onPageChangeListener)
    .load();

With PdfViewPager you can load and display PDF files easily. All the code you need is:

PdfViewPager pdfViewPager = new PDFViewPager(this, "sample.pdf");
setContentView(pdfViewPager);

Or you can embed it in your layout like this:

<es.voghdev.pdfviewpager.library.PDFViewPager
  android:id="@+id/pdfViewPager"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  app:assetFileName="sample.pdf"/>

Have a look at the lib if you want to know more.
