Question

What is the best way to pass variable data from an Activty to a non-Activty class? The data is created within the onCreate of the first Acivity I need to pass that data to the second class without the use of Intent. Any code samples would be appreciated.

Since I got it to work like I intended it to post what I have. In my case I already had a Constructor that was an ArrayList and for what I was doing I needed another one of the same type. So here goes:

ClassActivity

public class Polygon extends Overlay {
ArrayList<GeoPoint> geoPoints;

public Polygon(ArrayList<GeoPoint> points){
    geoPoints = points;
}

public class Hex{
    public Hex(ArrayList<String> str) {
        // TODO Auto-generated constructor stub
     Log.i("string",str.toString());
    }
  }

and My main Actvity has

 Polygon main = new Polygon(null);
 Polygon.Hex mMainClass = (main.new Hex(color));

Note that I had to create an instance of the main class before

Polygon.Hex mMainClass = (main.new Hex(color));

Answer 1

If your Class Name is MainClass then Create Constructor for that and pass value as a parameter, below is a example for that.

MainClass.java

public class MainClass {
    public MainClass(int i, String str) {
        // TODO Auto-generated constructor stub

    }
}

Use below code for Pass Value from MainActivity to MainClass, Here i is integer variable and str is a String variable

MainClass mMainClass = new MainClass(i, str);
