Finish All Previous Activities

Finish all previous activities

Use:

Intent intent = new Intent(getApplicationContext(), Home.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);

This will clear all the activities on top of home.

Assuming you are finishing the login screen when the user logs in and home is created and afterward all the screens from 1 to 5 on top of that one. The code I posted will return you to home screen finishing all the other activities. You can add an extra in the intent and read that in the home screen activity and finish it also (maybe launch login screen again from there or something).

I am not sure but you can also try going to login with this flag. I don't know how the activities will be ordered in that case. So don't know if it will clear the ones below the screen you are on including the one you are currently on but it's definitely the way to go.

Finish all previous activities from other activity

try this solution..

Intent i = new Intent(FirstActivity.this, SecondActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
           Intent.FLAG_ACTIVITY_CLEAR_TASK |
           Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);

hope it helps.

Finish all activities at a time

Whenever you wish to exit all open activities, you should press a button which loads the first Activity that runs when your application starts then clear all the other activities, then have the last remaining activity finish.
to do so apply the following code in ur project

Intent intent = new Intent(getApplicationContext(), FirstActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("EXIT", true);
startActivity(intent);

The above code finishes all the activities except for FirstActivity.
Then we need to finish the FirstActivity's
Enter the below code in Firstactivity's oncreate

if (getIntent().getBooleanExtra("EXIT", false)) {
    finish();
}

and you are done....

Finish all activities but keep the first

Try this i.e, if you want to close all activities except MainActivity and open otherActivity from this.

Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |  Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivity(intent);

Destroy All Previous Activities After Specific Activity is Open

Intent intent = new Intent(ActivityC.this, ActivityD.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);

FLAG_ACTIVITY_NEW_TASK

If set, this activity will become the start of a new task on this
history stack. A task (from the activity that started it to the next
task activity) defines an atomic group of activities that the user can
move to. Tasks can be moved to the foreground and background; all of
the activities inside of a particular task always remain in the same
order. See Tasks and Back Stack for more information about tasks.

This flag is generally used by activities that want to present a
"launcher" style behavior: they give the user a list of separate
things that can be done, which otherwise run completely independently
of the activity launching them.

When using this flag, if a task is already running for the activity
you are now starting, then a new activity will not be started;
instead, the current task will simply be brought to the front of the
screen with the state it was last in. See FLAG_ACTIVITY_MULTIPLE_TASK
for a flag to disable this behavior.

This flag can not be used when the caller is requesting a result from
the activity being launched.

FLAG_ACTIVITY_CLEAR_TASK

If set in an Intent passed to Context.startActivity(), this flag will
cause any existing task that would be associated with the activity to
be cleared before the activity is started. That is, the activity
becomes the new root of an otherwise empty task, and any old
activities are finished. This can only be used in conjunction with
FLAG_ACTIVITY_NEW_TASK.

Android: Remove all the previous activities from the back stack

The solution proposed here worked for me:

Java

Intent i = new Intent(OldActivity.this, NewActivity.class);
// set the new task and clear flags
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(i);

Kotlin

val i = Intent(this, NewActivity::class.java)
// set the new task and clear flags
i.flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK
startActivity(i)

However, it requires API level >= 11.
