Android: First run popup dialog

Question

I am trying to make a popup dialog that only shows after the app\'s first run that will alert users of the new changes in the app. So I have a dialog popup like this:

<

Answer 1

 loginPreferences = getSharedPreferences("loginPrefs", MODE_PRIVATE);
 loginPrefsEditor = loginPreferences.edit();
 doFirstRun();

 private void doFirstRun() {
        SharedPreferences settings = getSharedPreferences("PREFERENCE", MODE_PRIVATE);
        if (settings.getBoolean("isFirstRun", true)) {
            loginPrefsEditor.clear();
            loginPrefsEditor.commit();
            SharedPreferences.Editor editor = settings.edit();
            editor.putBoolean("isFirstRun", false);
            editor.commit();
        }
    }

I used this code to ensure that its the first time someone runs the application. The loginPrefsEditor is cleared from data because i have a "Remember Me" Button which stores the data to the sd card. Hope it helps !
