LeakCanary not giving enough information to identify leak

I'm using LeakCanary but the heap analysis result doesn't provide enough information to detect any leak. It only mentions that the activity is leaking.

All I know from this trace is SelectActivity is leaking. But I can't figure out why? The activity itself is 1000+ lines and I was hoping if there's any shortcut other than going though every line and checking for a possible leak candidate.

Does the activity register any broadcast receiver? The leaktrace shows LoadedApk.mReceivers which is an ArrayMap of receivers to receiver dispatcher and the activity is the receiver dispatcher.
