Question

Is it possible to save an entire array (or even ArrayList) to the android app data?

As far as I know you can only do stuff like putInt, putBoolean or putString….
But what about more complex data-types?
Is there a way to do that?

Or do I have to convert the whole array to a String first, and then parse it to an array again on load?

Answer 1

for complex data-types use

            Bundle bundle = new Bundle();
            bundle.putSerializable("key", object);
            intent.putExtra("bundle", bundle);

EDit: or for Arrays use

   putStringArray(key,value);
