Can we use takePicture() in android without camera preview? I need to take a picture secretly for security purposes

I tried few codes from here :

How to capture an image in background without using the camera application

and this

Android Camera API Tutorial.

This question may seem duplicated, but I really want to know that can this be done over API level 21?

Thanks in advance.

According to android.developer.com, no.

https://developer.android.com/reference/android/hardware/Camera.html

"Important: Call startPreview() to start updating the preview surface. Preview must be started before you can take a picture."
