you can try getter setter method for transferring values between two classes. I think that would be best for your project.

For e.g. 

private String myValue; 

public void setValue ( String myValue )
{
     this.myValue = myValue;
}

public String getValue()
{
      return myValue;
}

Make it public static and you will be able to pass your ArrayList to Another Class. But, better way would be to use Serializable or Parcelable to pass it.

UPDATE

Application Class From the Docs.

Base class for those who need to maintain global application state. You can provide your own implementation by specifying its name in your AndroidManifest.xml's tag, which will cause that class to be instantiated for you when the process for your application/package is created

Other Option is you can create a class that extends Application and you can use a getter setter for the ArrayList there in the Application class. Application Class is available to your whole Application and you can get the values everywhere using the Application Context.

This would help u i think.

**page1.java**

    static ArrayList<ArrayList<String>> stringList1; 

    public static ArrayList<ArrayList<String>> getstringList1()
    {
        return stringList1;
    }

**page2.java**

    ArrayList<ArrayList<String>> mystringList1  = page1.getstringList1();
