Android: unique memory exception. How to check objects?

Here's the setting:

  • I have an activity with a list of elements (updated from the server, represented by a simple Java class). Elements are displayed through a custom BaseAdapter and a custom view for each row.
  • Elements are implemented by Parcelable, so when the screen is rotated, the elements are saved as a ParcelableArrayList and then restored without returning to the server.

This is still a fairly simple setup, but I want to transfer one of these elements to another activity. The bundle has a pubExtra (String, Parcelable) method that I wanted to use to place the object there and then pass it using intent. When I did this, the device began to receive power due to an OutOfMemoryException. It seems, trying to parallelize the object, it asks for ~ 30mb (!)

It seems that the object should contain references to something else, since the object itself contains only a few int / float / String fields and the methods associated with them. I was not able to track this by looking at the code inspector or debugging, and I don't know how to use the heap viewer effectively.

Any suggestions?
