Answer 1

I know its an old post.But updating for new comers.

From API21 Camera class is deprecated.Instead we have to use Camera2 class. For gettng connected devices,you have to use something like

private CameraManager mManager;
private String[] mCameraIds;
mManager = (CameraManager)getSystemService(Context.CAMERA_SERVICE);
mCameraIds = mManager.getCameraIdList();

You can find documentation here

Answer 2

That method was not introduced until API Level 9 (Android 2.3). You cannot use it on older versions of Android. Here is a sample project demonstrating how to use it on newer versions of Android while safely avoiding it on older versions of Android.
