Remember selection and act accordingly on next launch

Question

I'm building an application that asks the user to select one option (41 languages) from multiple choices on application launch and in bottom there is a toggle button wich is off by default. If the user sets it on "on" I want my application to remember this selection and go to that language option at launch, ignoring the language selection page.

I'm pretty new to android development, I would appreciate if the answer would include some example code so I can modify it and learn while modifying it.

Thank you.

SharedPreferences is what you need.

// here you get an instance of SharedPreferences for your app
Context context = getActivity();
SharedPreferences sharedPref = context.getSharedPreferences(
        getString(R.string.preference_file_key), Context.MODE_PRIVATE);

// editor is required to apply changes to existing SharedPreferences
SharedPreferences.Editor editor = sharedPref.edit();
editor.putInt(getString(R.string.saved_high_score), newHighScore);
editor.apply();

// this is a way that you take stored values back from the SharedPreferences
int defaultValue = getResources().getInteger(R.string.saved_high_score_default);
long highScore = sharedPref.getInt(getString(R.string.saved_high_score), defaultValue);
