Take photo in background without UI. Android

Question

i'm looking for code that will take pictures in background and save it to Bitmap. I did some research and found this: https://stackoverflow.com/a/17859926/7391954 it kinda works but it freezes UI even if I call takePicture from worker thread and it cannot take photos faster than like 1/sec (I'd like 3/sec). Can anyone help me at this?

I don't want to display preview, it has to take picture in background without UI. – VIAX Sep 10 '17 at 11:21
I know it, you can overlay your main view on surfaceView, or make surfaceView visibility invisible – Behnam Eskandari Sep 10 '17 at 11:23

Here's camera preview code that worked for me: https://stackoverflow.com/a/33242595/7391954 I overlaid my layout on it and then taking photo was as simple as calling getBitmap() on that View.
