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

Accepted Answer

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.
