Obviously Leaked Window Exception will come in your code.

You are not supposed to change the Activity while showing the dialogue (Because your context will be get changed).

So , you have to continuously check the current context and if there is any change in your current context you should dismiss the dialogue .

In your case dismiss the dialogue just before you start a new Activity

Update

Normal dialogue will be automatically get cancelled.Here is a tricky way to achieve the Login check. 

alert.setOnShowListener(new DialogInterface.OnShowListener() {
        @Override
        public void onShow(DialogInterface dialog) {
            Button button = alert.getButton(AlertDialog.BUTTON_POSITIVE);
            button.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {

                  // Code to check the login credentials.
                  if(everythingIsOK)
                  {
                   dialogue.dismiss();
                 }
                 else
                 {
                   // Acknowledge the user 
                     }

                }
            });
        }
    });
