Answer 1

The problem occurs when your custom class has for property some other class e.g. "Bitmap". What I made is to change the property field from "private Bitmap photo" to "private transient Bitmap photo". However the image is empty after I getIntent() in the receiver activity. Because of this I passed the custom class to the intent and also I've created a byte array from the image and pass it separatly to the intent:

selectedItem is my custom object and getPlacePhoto is his method to get image. I've already set it before and now I just get it first than convert it and pass it separatly:

 Bitmap image = selectedItem.getPlacePhoto();
 image.compress(Bitmap.CompressFormat.PNG, 100, stream);
 byte[] byteArray = stream.toByteArray();
 Intent intent = new Intent(YourPresentActivity.this, 
 TheReceiverActivity.class);
 intent.putExtra("selectedItem", selectedItem);                 
 intent.putExtra("image", byteArray);
 startActivity(intent);            

`

Then in the receiver activity I get my object and the image as byte array, decode the image and set it to my object as photo property.

 Intent intent = getIntent();
 selectedItem = (ListItem) intent.getSerializableExtra("selectedItem");
 byte[] byteArray = getIntent().getByteArrayExtra("image");
 Bitmap image = BitmapFactory.decodeByteArray(byteArray, 0, 
 byteArray.length);
 selectedItem.setPhoto(image);
