Did you try the continuous autofocus mode FOCUS_MODE_CONTINUOUS_VIDEO (starting from API level 9)? In this mode, focus is automatically adjusted permanently (it worked well for me)

See the documentation at http://developer.android.com:

  • On my samsung note3(KitKat) FOCUS_MODE_CONTINOUS_VIDEO seems to work better than FOCUS_MODE_CONTINOUS_PICTURE. – ChinLoong Jun 07 '16 at 08:22
