How to restart my android application on settings change?

Question

I am developing a bilingual application. I want it to get fully restarted on language settings change. Here is the code I am using:

Intent restartIntent = getBaseContext().getPackageManager()
                            .getLaunchIntentForPackage(getBaseContext().getPackageName() );
    PendingIntent intent = PendingIntent.getActivity(getBaseContext(), 0, restartIntent,     Intent.FLAG_ACTIVITY_CLEAR_TOP);
    AlarmManager manager = (AlarmManager) getBaseContext().getSystemService(Context.ALARM_SERVICE);
    manager.set(AlarmManager.RTC, System.currentTimeMillis() + 1, intent);
    System.exit(2);

This works fine except that after the app is restarted, I have two main activities (the old one still remains). How can I solve this issue?

Answer 1

Add finish(); to your current Activity

Intent restartIntent = getBaseContext().getPackageManager()
                            .getLaunchIntentForPackage(getBaseContext().getPackageName() );
    PendingIntent intent = PendingIntent.getActivity(getBaseContext(), 0, restartIntent,     Intent.FLAG_ACTIVITY_CLEAR_TOP);
    AlarmManager manager = (AlarmManager) getBaseContext().getSystemService(Context.ALARM_SERVICE);
    manager.set(AlarmManager.RTC, System.currentTimeMillis() + 1, intent);
    finish();
    System.exit(2);
