Started Blog Reader Project, now Crystal Ball App has errors

Hi folks,

I completed the Crystal Ball App, (yay me!) and moved on to the Blog Reader App.

I downloaded the new development package from Google as instructed in the videos (I had been using the treehouse version that it tells you to use to build the Crystal Ball app) and put my crystal ball into the new workspace.

Now my Crystal Ball has errors. It was fine before I upgraded Eclipse.

In the console it says "Unable to resolve target 'android-16'

And in the file with my random answers it has a bunch of errors, but I don't know what is wrong or how to fix it.

here is the code

package net.johannson.thesuperpredictor;

import java.util.Random;

public class SuperPredictor { //Member variables (properties about the object) public String [] mAnswers = { "Booyah!", "No way", "Maybe", "I'm not going to tell you", "Yes, if you clean your room" };

//Methods (abilities: things the object can do)
public String getAnAnswer() {

    String answer = "";

    //Randomly select one of the answers
    Random randomGenerator = new Random(); //Construct a new Random number generator
    int randomNumber = randomGenerator.nextInt(mAnswers.length);

    answer = mAnswers[randomNumber];  

    return answer;

}

}
