It seems like Xamarin is not using the right theme if the Target SDK is automatically selected by Xamarin Studio.
I created an example project that uses the Material design with DrawerLayout and AppBarLayout and specified the statusBarColor as transparent. No matter what application theme I specify, the status bar of the application remains dark(black background). However, if I specify the target SDK in the project's options or directly in the manifest and override the value to target the API 25, the status bar gets the correct color(based on the colorPrimary / colorAccent etc).
Is this behaviour intended? I would expect having the same behaviour when the value is specified in the options and when the target SDK is chosen automatically(as the select automatically option is showing that the API 25 is the target).
