Android: Remove all the previous activities from the back stack

Question

When i am clicking on Logout button in my Profile Activity i want to take user to Login page, where he needs to use new credentials.

Hence i used this code:

Intent intent = new Intent(ProfileActivity.this,         LoginActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);  intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent); 

in the onButtonClick of the Logout button.

But the problem is when i click device back button on the Login Activity it takes me to the ProfileActivity. I was expecting the application should close when i press device back button on LoginActivity.

What am i doing wrong?

I also added android:launchMode="singleTop" in the manifest for my LoginActivity

Thank You

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.
