In my android app, i am using this line of code:
SharedPreferences myPrefs = getSharedPreferences("myPrefs", MODE_PRIVATE);
Set<String> set = myPrefs.getStringSet("list", new HashSet<String>());
but i am getting following error:
The method getStringSet(String, HashSet) is undefined for the
type SharedPreferences
Why am i getting this error? Thanks in advance.
getStringSet is available from API Level 11 (Android 3 Honeycomb).
Check which Android version you defined in the project.
