background-size:cover on Android native browser

Problem:
Background image is not full screen on Android native browser by using the following css:
background: url(‘…’) fixed center center / cover;

Solution:
Separate background-image from others and use it inline.

Then use each option separately in css file.
background-size: cover;
background-position: center center;
