How to store login information?

Question

Java

hello, I'm making an app on android studio, did the registration related to firebase, but after logging into the account, in the app, and reloading the app, it asks to login again.
the question is how to fix it, if you need a code, let me know, I’ll say right away, I didn’t do it according to the ready-made android studio template, but through a dialog box.

Answer 1

Give code to loginActivity. In general, something like this should work. I'm writing from the phone, so I wrote an approximate solution!

If(пользователь != null) {
startActivity(new Intent(LoginActivity.this, MainActivity.class));
finish();
}
