如何使用pdfview在android中打开PDF

我正在使用android-pdfview-1.0.2.jar我在这里找到它链接到主项目在这里我试图加载PDF如下

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

我在我的布局中添加了pdfView，如下所示

执行时我收到以下错误：
