How can I close my previous

Answer 1

you can add a List in Application that save every activity you created. and when you exit, you just need to finish all activity in the list.

you can use this
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

from this question answer How to exit from the application and show the home screen?

Answer 3

put this line of code in your application System.exit(2);

Answer 4

Intent intent = new Intent(this, LoginActivity.class);
ComponentName cn = intent.getComponent();
Intent mainIntent = IntentCompat.makeRestartActivityTask(cn);
startActivity(mainIntent);

Description:

public static Intent makeRestartActivityTask (ComponentName mainActivity)

Make an Intent that can be used to re-launch an application's task in its base state. This is like makeMainActivity(ComponentName), but also sets the flags FLAG_ACTIVITY_NEW_TASK and FLAG_ACTIVITY_CLEAR_TASK.

1) Activity lifecycle

2) Shutting down Activity and managing Activities lifecycle
