我试图通过我的Android应用程序来查看PDF文件，而我使用这个库： https://www.nuget.org/packages/Xamarin.PdfView.Android/的Android，试图Xamarin的Android应用程序中查看PDF
这里是我的代码看喜欢什么：
C＃ ：
using Com.Joanzapata.Pdfview;
using Java.IO;
namespace Xamarin_test
{
[Activity(Label = "Xamarin", MainLauncher = true, Icon = "@drawable/icon")]
public class MainActivity : Activity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
SetContentView(Resource.Layout.Main);
PDFView pdfView = FindViewById<PDFView>(Resource.Id.pdfview);
pdfView.FromAsset("test.pdf")
.DefaultPage(1)
.ShowMinimap(false)
.EnableSwipe(true)
.Load();
}
}
}
XML：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<com.joanzapata.pdfview.PDFView
android:id="@+id/pdfview"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
，当我尝试运行它，我收到此错误：
了java.lang.RuntimeException：在执行doInBackground时出错（）
是什么原因造成的？
谢谢。
