Declaring Features
Your camera implementation works great now. One more task remains: Tell potential users about it. When your app uses a feature like the camera – or near-field communication, or any other feature that may vary from device to device – it is strongly recommended that you tell Android about it. This allows other apps (like the Google Play Store) to refuse to install your app if it uses a feature the device does not support.
To declare that you use the camera, add a <uses-feature> tag to your AndroidManifest.xml.
