Regardless of the API level, Check String arrays and Object arrays in SharedPreferences

SAVE ARRAY

public boolean saveArray(String[] array, String arrayName, Context mContext) {        SharedPreferences prefs = mContext.getSharedPreferences("preferencename", 0);       SharedPreferences.Editor editor = prefs.edit();       editor.putInt(arrayName +"_size", array.length);       for(int i=0;i<array.length;i++)           editor.putString(arrayName + "_" + i, array[i]);       return editor.commit();   }

LOAD ARRAY

public String[] loadArray(String arrayName, Context mContext) {       SharedPreferences prefs = mContext.getSharedPreferences("preferencename", 0);       int size = prefs.getInt(arrayName + "_size", 0);       String array[] = new String[size];       for(int i=0;i<size;i++)           array[i] = prefs.getString(arrayName + "_" + i, null);       return array;   }
