Is this correctly formatted?

Why making it singletop?

[BigBossZhiling, 2016/02/09 01:03:11]

After coming back from advanced ui setting, I want the user to go back to the
exact same custom ui activity that the user was on.

[Ian Wen, 2016/02/10 02:36:06]

If you use startActivityForResult() in CustomUIActivity and and receive result
later. This way you do not need to set this activity to be singleTop.
