我正在尝试在我的应用中实现pdf viewer。
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.ttech"
android:versionCode="1"

<application

<activity

android:label="@string/title_activity_splash_screen"

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity

android:label="@string/app_name" >

android:label="@string/title_activity_audio" >
</activity>
<activity android:name=".PdfViewerActivity"

我得到的错误是: -
E/AndroidRuntime(828): android.content.ActivityNotFoundException: Unable to find explicit activity class {com.example.ttech/net.sf.andpdf.pdfviewer.PdfViewerActivity}; have you declared this activity in your Android manifest
答案 0 :(得分:2)
您将活动声明为
<activity android:name=".PdfViewerActivity"
android:label="@string/title_activity_pdf_viewer" />
由于您定义了package="com.example.ttech"
,因此该活动指向了班级com.example.ttech.PdfViewerActivity
,但您希望改为使用net.sf.andpdf.pdfviewer.PdfViewerActivity
。
因此,您必须使用绝对包名称
定义活动<activity android:name="net.sf.andpdf.pdfviewer.PdfViewerActivity"
android:label="@string/title_activity_pdf_viewer" />
