"cannot find symbol return mTitle;"

I'm not sure what is going on...

PictureBook.java 
public class PictureBook {
  String mTitle() {

  return mTitle;

  }
}

The 'cannot find symbol' error is an error about identifiers. In your case the compiler can't identify the variable name of mTitle since you haven't declared it before. Something like this would solve the problem

public class PictureBook {
  String mTitle() {
    String mTitle = "";
    return mTitle;
  }
}

You have not defined mTitle, and as such you are probably getting a NullPointerException.
