Android MuPDF错误

Question

我想添加MUPDF来源到我的项目并在我的应用程序显示PDF文件。

我在下面

http://mupdf.blogspot.com/ 

的链接，并添加类到项目像这里写

http://pastebin.com/YzHUhzE7 

毕竟这些步骤现在我要显示在活动PDF文件我app

Uri uri = Uri.parse("/storage/sdcard0/A.pdf"); 

    Intent intent = new Intent(this, MuPDFActivity.class); 

    intent.setAction(Intent.ACTION_VIEW); 

    intent.setData(uri); 

    this.startActivity(intent); 

但是我从LogCat中得到这些错误

这里是我的应用程序的AndroidManifest.xml标签：

    <activity android:name="OutlineActivity" 
       android:label="@string/outline_title">

可以采取什么问题吗？我该如何解决它？

Answer 1

Caused by: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.example.andpdfviewer/com.artifex.mupdfdemo.MuPDFActivity}; have you declared this activity in your AndroidManifest.xml? 

仔细检查清单文件并声明它的活动/修复它。
