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.
