You are using watching the reference at the wrong time. You should only call watch(thing) when you are absolutely certain that thing will be garbage collected. For your Activities and Fragments, you will want something like this:

@Override public void onDestroy() {
    super.onDestroy();
    RefWatcher refWatcher = ExampleApplication.getRefWatcher(getActivity());
    refWatcher.watch(this);
}

That is from the LeakCanary FAQ "How do I use it?" section
