I tried below code to make this work change it to suit your needs
SharedPreferences wmbPreference = PreferenceManager.getDefaultSharedPreferences(this);
boolean isFirstRun = wmbPreference.getBoolean("FIRSTRUN", true);
if (isFirstRun)
{
// Code to run once
SharedPreferences.Editor editor = wmbPreference.edit();
editor.putBoolean("FIRSTRUN", false);
//editor.commit();
editor.apply();
}
