CWAC camera autofocus() and flashmodes issue

Question

I am using a Xiaomi RedMi running Android 4.4.4. I am using the demo project as a reference for my DemoCameraFragment. When the camera starts up the first time, isAutofocusAvailable() returns false. After taking the first pic in SingleShotMode, I click on my "take next pic button" in which I call restartPreview(). For some reason, isAutofocusAvailable() now returns true and I can call autofocus successfully.

Now when I call getFlashMode(), when my app starts I get a Null Pointer Exception(Which I think occurs on the camera object). However, after I take the first pic and click on the "take next pic" button"( I call restartPreview() here), getFlashMode() no longer gives me a null pointer exception.

What exactly am I missing out setup-wise? I am using Android Annotations so my first call to both autofocus and getFlashMode is in @AfterViews annotated function. Why are Autofocus and getFlashMode not working for the first call?
