No, sqlite is not needed.

Local application settings such as night mode preference are typically stored in SharedPreferences.

You can just save a variable in the SharedPreferences of the app for the preferred user settings and set theme on launch. Go through the documentation to know more .SharedPreferences

Rule of thumb - provide a link rather than the "Go through the documentation". Have a happy contributing! – RevakoOA May 28 '20 at 14:16

Please, check Shared Preferences. This is key-value storage and it's exactly suited for such needs.

As general practice - create some SharedPrefManager and move all logic with shared preferences there. Like in this answer.

Write this code on the first page that runs

 SharedPreferences pref = getApplicationContext().getSharedPreferences("nightMode", 0);
    if(pref.getBoolean("mode",false)){
        // code change ui to night
    }

and Write this code on the night mode switch

    SharedPreferences pref = getApplicationContext().getSharedPreferences("nightMode", 0);

    pref.edit().putBoolean("mode",true).apply();

Just as easily
