I Have a MasterDetailPage on Xamarin.Forms and I switched the flow direction to RightToLeft. It works as expected on UWP and iOS but not on Android. Anyone knows why? On Android it still showing as LeftToRight...
According to Xamarin Documentation Here you should set supportsRtl to true in the application manifest in android project
android:supportsRtl="true"
and if you want to enforce supporting RTL without changing device language you should add this code to your MainActivity.cs in "OnCreate" Method
Window.DecorView.LayoutDirection = LayoutDirection.Rtl;
