As a developer aspiring to be a mobile developer, I have published one Android app, working on a second, but this is slow going as it is outside of my day job. A question I don't have the answer to is, how do I know when enough is enough to start calling myself experienced? I can launch intents, activities, use SQLite, get to the GPS, Accelerometers, and more, but I have a hard time getting apps to market that prove all of this, since an app is more then just a technical checklist of features. How can I effectively demonstrate to a potential employer I have the technical chops? PS. I can relocate if you were wondering =)
