come aprire PDF in Android usando pdfview

Question

Sto usando android-pdfview-1.0.2.jar ho trovato here Link al progetto principale è here che sto cercando di caricare PDF come segue

PDFView pdfView= (PDFView) findViewById(R.id.pdfView); 
pdfView.fromAsset("sample.pdf") 
.defaultPage(1) 
.showMinimap(false) 
.enableSwipe(true) 
.onLoad(this) 
.onPageChange(this) 
.load(); 

I hanno aggiunto pdfView nel mio layout, come illustrato di seguito

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" > 

    <com.joanzapata.pdfview.PDFView 
     android:id="@+id/pdfView" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" /> 

</FrameLayout> 

durante l'esecuzione sto ottenendo seguente errore:
