static List<ArrayList<String>> mystringList1 = new ArrayList<ArrayList<String>>();
 mystringList1 = page1.stringList1;

    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.
