How to make an android application run without hiding the status bar?

Question

Android

I installed android 5, I don’t know, maybe it was before, but I noticed only now that Google applications, such as Hangouts and GMail, are launched, as it were, under the status bar, not from below it, without overlapping it, namely under it (or behind them), giving it the background color of the application itself. Those. the status bar turns red for Gmail and green for Hangouts. What needs to be written in the manifest so that the application starts in the same mode?

If you can't open SDK https://developer.android.com/training/material/th...
then you can google "android change status bar color"
