Android MuPDF錯誤

Question

我想添加MUPDF來源到我的項目並在我的應用程序顯示PDF文件。

我在下面

http://mupdf.blogspot.com/ 

的鏈接，並添加類到項目像這裏寫

http://pastebin.com/YzHUhzE7 

畢竟這些步驟現在我要顯示在活動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); 

但是我從LogCat中得到這些錯誤

這裏是我的應用程序的AndroidManifest.xml標籤：

<application 
    android:allowBackup="true" 
    android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name"

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

可以採取什麼問題嗎？我該如何解決它？

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? 

仔細檢查清單文件並聲明它的活動/修復它。
