Android and Iphone Applications

Hi, I'm looking for enterprise level sample applications code for Android and Iphone for my practice. You need to explain me the code base. I don't need basic applications. It would be nice to use features like bluetooth, camera api and web services etc ... more complicated the application better it is. I just learned to code in these platforms so I need to practice more advance features in a real time scenario. The code base will be used only for learning purpose. If you did certain projects you can mix around the code and provide me. Thanks
