Android: open activity without save into the stack

Question

I have 2 activities: Main and List.

From Main you can open List; from List you can open Main.

I\'d like it so that every opening of List does not

Answer 1

It seems, if you call finish() on your activity right after you have opened another, the one that is finished is removed from the stack.

for example:

Intent intent = new Intent(this, NextActivity.class);
startActivity(intent);
finish();

Answer 2

Just wanted to add a way to do this in Kotlin:

val i = Intent(this, LogInActivity::class.java)
startActivity(i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK))

Answer 3

add the flag FLAG_ACTIVITY_NEW_TASK to your Intent

http://developer.android.com/reference/android/content/Intent.html#FLAG_ACTIVITY_NEW_TASK

Answer 4

In the manifest file add:

android:noHistory="true" 

to the activity that you don't want to keep on the stack.

Answer 5

Try FLAG_ACTIVITY_CLEAR_TOP if the activity is already running:

Intent intent = new Intent(this, MyActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);

Answer 6

Late answer, but adds some depth to other answers. It all comes down to what do you want to happen with other activities started from that activity

Option 1 - Just this one activity should not have history of calling activity

Then just do:

Intent i = new Intent(...);
i.addFlag(Intent.FLAG_ACTIVITY_NO_HISTORY);
startActivity(i);

Option 2 - All activities started from that specific activity should not have history

Then add in manifest of the calling activity:

android:noHistory="true" 

But if you do want to have history in new activity, then you have to manually remove the flag:

Intent i = new Intent(...);
i.removeFlag(Intent.FLAG_ACTIVITY_NO_HISTORY);
startActivity(i);

Hope that clears up other answers :)
