Question

我在my.cs中收到此错误：

Android.Content.ActivityNotFoundException：无法找到显式活动类 {DesignLibrary_Tutorial.DesignLibrary_Tutorial / com.artifex.mupdfdemo.MuPDFActivity}; 你有没有在AndroidManifest.xml中声明这个活动？

这是my.cs代码：

File file = (File)fileFromAsset(this, "test.pdf");
var uri = Android.Net.Uri.Parse(file.AbsolutePath);
var intent0 = new Intent(this, typeof(MuPDFActivity));
intent0.SetFlags(ActivityFlags.NoHistory);
intent0.SetAction(Intent.ActionView);
intent0.SetData(uri);
StartActivity(intent0);

这是我的android.manifest标签：

<?xml version="1.0" encoding="utf-8"?>

<activity android:name="com.artifex.mupdfdemo.MuPDFActivity">
  <intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="application/vnd.ms-xpsdocument" />
  </intent-filter>
  <intent-filter>
    <action android:name="android.intent.action.VIEW" />

  </intent-filter>
