's ListView 's onItemClickListener to null which will release the reference to the listener an make whatever memory allocated within that listener to be eligible for GC. This way you won't get OOM. It's just a workaround and the real solution.. and can be GCed. But at the same time a new junk needs to be created after the rotation and because of the mem alloc size 10M per junk this will cause OOM. The solution is to break any references to the listener the junk owner in this case..
