In the login activity when you start intent, immediately include finish(). This kills the present activity as shown below:

Intent intent = new Intent(first.java,second.class);
startActivty(intent);
finish();

You can also try with including android:launchMode="singleInstance" in your android manifest file for the activty as shown below:
