Android Status bar and Navigation issues

[Android Central Question]

Recently I used this java code in Main_Activity:

(getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS))
for status Bar Transparent purpose. All went well, but my Android Navigation Bar also went to transparent policy. Now I need only transparent my Status Bar, but not the Navigation Bar.

I've moved this to the Software Development and Hacking forum so it gets seen by more programmers.
