[FIXED] App login screen prompts user input despite already logging in

Issue

I've made a login screen on Android.

After the client enters their name and password, they are directed to another screen via intent.

However, there is a problem after signing in and then pressing the back button on the phone to leave the app. When opening the application for a second time after doing so, it again returns to the login screen.

How can I prevent this from occurring so it does not repeatedly ask for login information?

Solution

Clear the task when calling the next activity:

Intent intent = new Intent(this, NextActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);

This will clear the backstack and on pressing back, your application will close.
