Android - 重构后的ClassNotFoundException

Question

我最近使用Eclipse的重构命令在我的应用程序(它当前称为MyApp)中重构了类,包和文件夹名称,并且我没有得到ClassNotFoundException.我已经确保在代码库中的任何地方都没有旧名称的实例.我还删除了所有类文件\bin\classes和生成的Java文件\gen(两者都已重新生成,我已经检查过).我还将API级别从16更新到17,以尝试解决问题.这是堆栈跟踪:

这是我的清单.我知道硬编码字符串是糟糕的风格.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.myapp"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />
    <uses-permission 
        android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <application
        android:icon="@drawable/ic_launcher"
        android:name="MyApp"
        android:label="MyApp"
        android:theme="@style/NoActionBar">
        <activity
            android:name=".Otheractivity"
            android:label="Otheractivity">
        </activity>
        <activity 
            android:name=".MainMenu"
            android:label="MainMenu">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

关于问题可能是什么的任何想法？
