运行时异常无法在模拟器中运行应用程序

Question

我无法在模拟器中运行我的应用程序。

我的 androidManifest.xml 文件是

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="ch.adiuvaris.enigma"android:versionCode="1" android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<application android:icon="@drawable/icon" android:label="@string/appName" >
    <activity   android:label="@string/appName" android:name=".EnigmaPuzzle" >
        <intent-filter >
            <action android:name="android.intent.action.MAIN" />
         <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:label="Enigma Settings android:name=".GamePrefs" >
    </activity>
    <activity android:label="Enigma Help" android:name=".GameHelp" >
    </activity>
    <supports-screens android:anyDensity="true" android:largeScreens="true" android:normalScreens="true" android:resizeable="true" android:smallScreens="true">
    </supports-screens>
    </application>
    </manifest>'}

如果您使用的是 Eclipse，请尝试清理项目。您的清单尚未刷新，这就是为什么它抱怨在 com.example.enigme 中找不到类
