Unable to start activity, trouble with my own class

Question

I have a problem with my aplication. I have a class that I put the values correctly and works fine, I think, but when I try to get the values of my class that I have on a bundle, I have this error:

And this error appreas in this line:

points = (Point[]) myBundle.get("puntos");

I use this code to declare my Point array:

Point points[];

And I use this other code to put it on my bundle:

myIntent.putExtra("puntos", points);

I put my Point class code for more explication:

package com.example.en4dis;

public class Point implements java.io.Serializable {

/**
 * 
 */
private static final long serialVersionUID = -4910520794768384111L;


String _id; 
String _comment; 
String _calification; 
String _coords;
int _X;
int _Y;

public Point(String id, String comment, String calification, String coords, int x, int y)
{
    _id = id; 
    _comment = comment; 
    _calification = calification; 
    _coords = coords;
    _X = x;
    _Y = y;     
}

public String getID()
{
    return _id;
}

public String getComment()
{
    return _comment;
}

public String getCalification()
{
    return _calification;
}

public String getCoords()
{
    return _coords;
}

public int getPointX()
{
    return _X;
}

public int getPointY()
{
    return _Y;
}

}

Eclipse throwed an exception and I have to put the "private static final long serialVersionUID = -4910520794768384111L;" line to fix it, I don't know if this line is the problem or what. Can someone help me? Thanks!

Answer 1

Just try,

replace

points = (Point[]) myBundle.get("puntos");

with

Object[] objects = myBundle.get("puntos");
points = Arrays.copyOf(objects ,objects.length, Point[].class);

Let me know what happen.

You need the putSerializable method of the Bundle. Check this http://developer.android.com/reference/android/os/Bundle.html#putSerializable(java.lang.String, java.io.Serializable)
