发布您的清单文件。 –

我已发布@TheTokenizer –

什么你最有可能忘记。

<activity 
    android:name=".KaranganyarAttractionDetailFragment"> 
    </activity>

将以下代码复制并粘贴到清单中。

    android:targetSdkVersion="18" /> 

<application 
    android:allowBackup="true"

明显？我有很多这样的课程，我必须在清单中做什么？ –

创建新活动时，必须在应用程序的清单中指定 –

，因为应该在应用程序的清单中指定任何活动？ –

导航到您的项目目录中的AndroidManifest.xml文件。将此行放在<application></application>标记之间（应该有类似的东西）。

<activity android:name=".KaranganyarAttractionDetailFragment"></activity>

明显？我有很多这样的课程，我必须在清单中做什么？ –

是的 - 你需要声明清单中的Android应用程序中的每个Activity @YeftaAndrea – krodmannix

非常感谢，我会试试 –

使用此方法只是为应用程序添加名称。

<application 
     android:name="com.yeftaandrea.plesirsolo" 
     android:allowBackup="true" 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name"
