 Intent intent = new Intent(LoginActivity.this, WelcomeActivity.class);
 intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
 startActivity(intent);
 progressDialog.dismiss();

`CLEAR_TOP` only works if the Activity launch mode is `singleTop`. — EpicPandaForce, Feb 28 '20 at 12:03

Add three flags:

 intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
 intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
 intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);

CLEAR_TOP only work if you have single Top means only one activity So you also need to add Intent. Clear Task and Intent. New Task with your code that look like this in the below code

   intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
    Intent.FLAG_ACTIVITY_CLEAR_TASK |
    Intent.FLAG_ACTIVITY_NEW_TASK);

Sometimes it doesn't work you should add this line in your code

        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |Intent.FLAG_ACTIVITY_NEW_TASK | 
        Intent.FLAG_ACTIVITY_CLEAR_TASK);

It will help you and hopefully your issue will resolve. I've added this line in your code and after adding that line your code will look like this

 Intent intent = new Intent(LoginActivity.this, WelcomeActivity.class);
 intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
    Intent.FLAG_ACTIVITY_CLEAR_TASK |
    Intent.FLAG_ACTIVITY_NEW_TASK);
 startActivity(intent);
 progressDialog.dismiss();

Replace your code with the above code.
