Hello,
I try to send my own object to another activity class by using intent.putExtra("ownObject", ownObject);

OwnObject class looks like this:
public class OwnObject implements Serializable
{
private static final long serialVersionUID = 1L;
protected int member1= -1;
protected int member2= -1;
....
}
I send my intent like this:
Intent intent = new Intent(this,Screen2.class);
intent.putExtra("ownObject", ownObject);
startActivity(intent);
in screen2 I want to read the data using Bundle extras = getIntent().getExtras();

If I use for example intent.putExtra("int", new Integer(1234)); it works
What am I doing wrong?
Thanks

Hi Bobby,

it's not possible to send an object through an intent. So you're not doing anything wrong. Maybe there's another solution for your problem. Maybe you can use:

android.os.Parcelable

Interface for classes whose instances can be written to and restored from a Parcel. Class implementing the Parcelable interface must also have a static method "Object createFromParcel(Parcel)" which will be called when unmarshalling.

or

java.io.Serializable

Objects that want to be serialized/deserialized using ObjectOutputStream/ObjectInputStream should implement this interface.

Both can be used with an intent:

Thanks Jodol for your message. I need to find a way to send own objects between 2 or more activity classes, for example I have the main activity class that has some objects, it opens another screen (activity class),using startActivity(intent), the new opened class needs to receive that objects, the only problem is how..

I also tried :
1.
Bundle b = new Bundle();
b.putSerializable("myObject", myObject);
intent.putExtras(b);
2.
intent.putExtra("ownBundle1", b);
3.
intent.putExtra("myObject", myObject);
startActivity(intent);
Nothing worked ..
