Question

What is the difference between Intent.FLAG_ACTIVITY_CLEAR_TOP and finish() in Android?

Answer 1

The differerence between these two are as follows:

1.finish() you can use to end the activity in which you are right now present and also it will end one activity at one time.

2.In case of FLAG_ACTIVITY_CLEAR_TOP,It will end all the activities those are on top of the current activities inside the stack.There may be more than one activity.

Answer 2

suppose you are starting activities one after another in the order A-->B-->C-->D,ie activity B started from activity A,activity C started from activity B and so on. Now calling startactivity(A) from activity D with intent flag FLAG_ACTIVITY_CLEAR_TOP finishes all activities in between (here B and C) and starts A.

calling Finish() from your activity closes current activity
