1. If the Service and Activity classes are in the same package, I believe they should be able to access the same private storage space.

Bundle b = new Bundle();

// see Bundle.putInt, etc.
// Bundle.putSerializable for full Objects (careful there)
b.putXXXXX("key", ITEM);  
intent.putExtras(b);
startActivity(intent);

// -- later, in Activity
Bundle b = this.getIntent().getExtras();
int i = b.getInt("key");
