One of the great things about modern mobile phones is the increasingly good onboard camera. The Android API gives you seamless access to the camera from any other app, giving you plenty of scope to enhance existing apps or create new ones. There are two basic approaches to camera access: you can use an Intent to call the default camera app, or you can use the API to build your own camera Activity. The second is more flexible, but also requires more work to code. Often it's fine just to use the default app, and that's what we'll cover in this tutorial.
