How would you save and retrieve a spinners selection, so when you come back the same item on the spinner is selected? Maybe with shared preferences?

to Save data on the sharedPreferences( put this code on the onItemSelected() method and save the selected value's position of your spinner) :

int userChoice = spinner.getSelectedItemPosition();
SharedPreferences sharedPref = getSharedPreferences("FileName",0);
SharedPreferences.Editor prefEditor = sharedPref.edit();
prefEditor.putInt("userChoiceSpinner",usersChoice);
prefEditor.commit();

To get data from sharedPreferences :

SharedPreferences sharedPref = getSharedPreferences("FileName",MODE_PRIVATE);
int spinnerValue = sharedPref.getInt("userChoiceSpinner",-1);
if(spinnerValue != -1) {
  // set the selected value of the spinner 
  spinner.setSelection(spinnerValue);
}

refer this : set selection in spinner and this : get the position of the selected item in a spinner
