android what is wrong with openFileOutput?

by

Your method should be as follows. Takes in an extra Context as a parameter. To this method you can pass your Service or Activity

public static void save(String filename, MyObjectClassArray[] theObjectAr, 
  Context ctx) {
        FileOutputStream fos;
        try {
            fos = ctx.openFileOutput(filename, Context.MODE_PRIVATE);


            ObjectOutputStream oos = new ObjectOutputStream(fos);
            oos.writeObject(theObjectAr); 
            oos.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }catch(IOException e){
            e.printStackTrace();
        }
    }
