Java – garbage collection in Android (done manually)

I have a strange question I know that garbage collectors have their own limitations If assigned

So my question is, is it a good programming practice to call the mandatory garbage collector (system. GC ()) at the end of each activity?

to update

Everyone is saying, call system GC () does no good at all Then I wonder why it's here DVM will decide when to run the garbage collector What does that method need?

Update 2
