Answer 1

Well, to keep it short, you can't...Handler implements neithor Serializable nor Parcelable so it cannot be put as an extra...The Object Transported using Intents must follow eithor of those protocols.

Speculation I suppose, there's an alternative that would involve creating a Service to act as a middle man. But that'll require some testing.
