Using singleTask in launchMode

Question

I added singleTask attribute to MainActivity(A) to avoid loading the activity multiple times. After the other activity(B) is on MainActivity(A->B), if I go back to home screen by pressing home button and re-launch the application, there is no B (A->B->HOME->A)

There IS an answer in here, saying to add FLAG_ACTIVITY_CLEAR_TOP | FLAG_ACTIVITY_SINGLE_TOP every time calling A Activity.

BUT, I have a Intent data scheme in Manifest file, and the application should be launched by the scheme.

Please, help me...

if you want to resume your app..then why you use flags which will clear the activity stack.. — Ranjit, Jul 12 '14 at 17:43

It sounds to me like Android is launching your MainActivity(A) again after you return to the HOME screen. This shouldn't happen, but is a long-standing nasty Android bug. See my answer to this question for more information.
