Solution 1:

you can save list in sharedpreference like this:-

publicclassAppPreferences {
                    privatestaticSharedPreferences mPrefs;
                    privatestaticSharedPreferences.Editor mPrefsEditor;

                    publicstaticSet<String> getName(Context ctx) {
        mPrefs = PreferenceManager.getDefaultSharedPreferences(ctx);
        return mPrefs.getStringSet("nameList", null);
    }

    publicstaticvoidsetName(Context ctx, ArrayList<String> value) {
        mPrefs = PreferenceManager.getDefaultSharedPreferences(ctx);
        mPrefsEditor = mPrefs.edit();
        Set<String> set = newHashSet<>();
        set.addAll(value);
        mPrefsEditor.putStringSet("nameList", set);
        mPrefsEditor.commit();
    }

publicstaticvoidclearNameList(Context ctx) {
       mPrefs = PreferenceManager.getDefaultSharedPreferences(ctx);
        mPrefsEditor = mPrefs.edit();
        Set<String> set = newHashSet<>();
        mPrefsEditor.putStringSet("nameList", set);
        mPrefsEditor.commit();
    }
            }

to set list :-

setCamEval(activity, list);

to get list :-

getCamEval(this);
