I've recently refactored class, package and folder names in my app (it's currently called MyApp) using Eclipse's refactor command, and I'm not getting a ClassNotFoundException. I've made sure there are no more instances of the old name anywhere in the code base. I've also deleted all the class files in \bin\classes and generated Java files in \gen (both of which have regenerated, I've checked). I've also updated the API level from 16 to 17 in an attempt to solve the problem. Here is the stack trace:

Here is my Manifest. I know hardcoding strings is bad style.
<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>
Any ideas on what the problem could be?
android:name="MyApp" in your Manifest means you need to have MyApp.java, declaring the class MyApp extending Application in your com.myapp package.
