For inter-app communication Intents are a pretty reasonable solution to a complex problem. But inside an app, I would just love to have constructor parameters for my activities. I make do with Intents, but I don't have type safety, I have to deal with partially constucted objects until I've read my Intent Parameters and any time I have to pass something that's not in the default types that a bundle can contain I have to build a Parcelable wrapper for it, or find some other convoluted solution. Overall I just feel like I'm working at the wrong level of abstraction.
As alternatives, do people just end up dumping to an sqlite database and polling it in each Activity? Haha that'd be madness
