You need to have a reference to the other activity, from which you
would call your second (or third) activity's method to update the
coordinates
For example, your second activity could have a static method to return
the component/widget or entire activity.
SecondActivity.java
----------------------
public static Canvas getCoordinateCanvas() {
return this.myCanvas;
}
FirstActivity.java
--------------------------
private void someMethod() {
Canvas canvasToUpdate = SecondActivity.getCoordinateCanvas();
canvasToUpdate.<your update code>
}
