Your code is quite difficult to read on a text editor, because of the crazy naming convention. It's much more time than what I can devote today.
But if this SelectPlayer activity is the one opening in a wrong time, your problem is probably in the other activity, the one that has the startActivityForResult. About singleTop, if the "onCreate" for your SelectPlayer is called anyway, it could mean that it's not launched on the same "task" that the first one, or that the activity on top is not an instance of SelectPlayer, but another activity. It could give you a clue on where the problem could be.
