I've just refactored an app into a framework library and an application, but now when I try and start the app in the emulator I get the following error stack trace:

Usually this means that the
manifest file is wrong in some way, but I've double checked everything I can think of.
Here is my activity class:
package com.matthewrathbone.eastersays;
import
android.os.Bundle;
import com.rathboma.simonsays.Assets.Season;
import com.rathboma.simonsays.SeasonPicker;
import com.rathboma.simonsays.SimonSaysActivity;
public class EasterSimonSaysActivity extends SimonSaysActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
}
@Override
public SeasonPicker getSeasonPicker() {
return new SeasonPicker(){
@Override
public Season getSeason() {
// TODO Auto-generated method stub
return Season.EASTER;
}
};
}
}
As you can see, it's listed correctly in the manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.
android.com/apk/res/android"
package="com.matthewrathbone.eastersays"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="7" android:targetSdkVersion="15" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:name=".EasterSimonSaysActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="
android.intent.action.MAIN" />
<category android:name="
android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
I have no idea how to fix this, and would appreciate any help. I've scanned many similar questions on SO without seeing this particular behavior.
More info:
I've checked inside the generated APK and the class has an entry in
the classes.dex file
I've tried cleaning/building the project in
eclipse
I've tried using a totally new device image that doesn't have
a copy of the APK on it already
I've changed the library project into
a regular java, then changed back into an
android project, no
difference
