Android MuPDF错误

Question

我想将 MUPDF 源添加到我的项目并在我的应用程序上显示 pdf。

我在下面的链接中完成所有这些步骤

 http://mupdf.blogspot.com/

然后像这里写的那样将类添加到项目中

 http://pastebin.com/YzHUhzE7

现在我想在我的应用程序的活动中显示一个 pdf 文件

    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 得到这些错误

这是我应用的 AndroidManifest.xml 标签：

可能是什么问题？我该如何解决？

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将其声明为活动/修复它。
