Title bar appeared again after coming back in my application

问题:

In my application, I have applied following theme in my manifest file:

android:theme="@android:style/Theme.NoTitleBar.Fullscreen" 

and it is working fine.
But when I call someone from my app as per application requirement, and come back again in my application after call end, title bar appears in app again. I am not getting that what is the problem. Please help me out.

I don't want a title bar in my application at all.

This looks like a known issue:

Sounds like the following will fix it:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,  WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
