android os bundle,java - android.os.Bundle cannot be resolved in libgdx Android project - Stack Over...

I've just started using Libgdx to practice making games and I used the project creation .jar provided on the site to create the initial projects. However an error shows up in the Android project which says:

android.os.Bundle cannot be resolved.

I am using Eclipse for Java IDE. If I put the cursor over AndroidApplication which is underlined in red, it suggests that I configure the build path. I believe I have the Android SDK installed, because it worked a while back on a different workspace on a simple example project. Does anyone know what I might have done wrong in this new workspace? How can I configure the build path for the AndroidApplication class?

BTW, I believe I'm using Java 1.6 as that's what JAVA_HOME points to, although I've also got Java 1.7 installed. That might not be relevant though...

package com.example.drop;

import android.os.Bundle;

import com.badlogic.gdx.backends.android.AndroidApplication;

import com.badlogic.gdx.backends.android.AndroidApplicationConfiguration;

public class MainActivity extends AndroidApplication {

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

AndroidApplicationConfiguration cfg = new AndroidApplicationConfiguration();

cfg.useGL20 = false;

cfg.useAccelerometer = false;

cfg.useCompass = false;

initialize(new Drop(), cfg);

}

}
