Answer 1

Haven’t tried this but thought the questions was interesting.. so I went searching

In the Intent documentation there are quite a few different ArrayList type put??extra methods.
Depending on the type of your ArrayList you should use one of them.

ex

ArrayList<String> mGF = new ArrayList<String>();

Intent i = new Intent(mContext, ViewImages.class);
i.putStringArrayListExtra("package prefix"."whateverYouWannaNameIt",mGF);

Then you use getStringArrayListExtra(“package prefix”.”whateverYouWannaNameIt”)

I fell over this when I was looking around for some solutions for your problem that might help.
