or
pdfView.fromAsset(String)
    .pages(0, 2, 1, 3, 3, 3) // all pages are displayed by default

    .swipeHorizontal(false)
    .enableDoubletap(true)
    .defaultPage(0)
    // allows to draw something on the current page, usually visible in the middle of the screen
    .onDraw(onDrawListener)
    // allows to draw something on all pages, separately for every page. Called only for visible pages
    .onDrawAll(onDrawListener)
    .onLoad(onLoadCompleteListener) // called after document is loaded and starts to be rendered
    .onPageChange(onPageChangeListener)
    .onPageScroll(onPageScrollListener)
    .onError(onErrorListener)
    .onPageError(onPageErrorListener)
    .onRender(onRenderListener) // called after document is rendered for the first time

    .linkHandler(DefaultLinkHandler)
    .pageFitPolicy(FitPolicy.WIDTH) // mode to fit pages in the view
