How i can create with xamarin shell (android and ios) the Google Map effect (show app in full screen but not hide the status bar). Thx.
For Android i found:
In OnCreate method
Window.SetFlags(WindowManagerFlags.LayoutNoLimits, WindowManagerFlags.LayoutNoLimits);
Window.ClearFlags(WindowManagerFlags.TranslucentStatus);
Window.SetStatusBarColor(Android.Graphics.Color.Transparent);
But I still need to change the color of the icons?
No solution for iOS yet!

For Android:
1.Change the style.xml
You can add the code into the Android styles.xml. This can make the status bar transparent.
2.Adding method in MainActivity.cs.
For ios You can refer to this article .
