android - Is nullifying every views and listeners a good idea in finding or correcting leaks? -

-

i working on project , keep seeing methods nullify views , listeners on every ondestroy(). have seen code navigate rootview , set every listener null.

the original coder told me has done way prevent leaks, think causing more harm vm. think?

in opinion, unnecessary. once activity destroyed (i.e. ondestroy called) views , related listeners qualified garbage collection.

however, make sure not treating static activity and/or bound activity's context (that includes views too).
