I'm a design engineering undergrad and last summer had a job with a startup porting one of their iOS apps to Android. I had Android experience as I built a couple of calculators to be used in class. So my advice is build something small that you can use as a bargaining chip then approach as many startups as you can, telling them you need more experience and you'd like to help out on any projects they have going.
