title: API usage dilemma for my new Android App
body: <p>I am planning to develop a new Android app with a camera use case in it. Reading the API documentation it seems like Android's 'Camera.hardware' class has been deprecated and new 'android.hardware.camera2' has been introduced. So my question is should which API should I start making my app with? Is it a good idea to start developing my app with the deprecated API, so in that case at least I am not restricted to just Android L? And then later once I get good traction, use the new Camera APIs. Will the old APIs work for Android L too ? What would be a good strategy? </p>
