It doesn't work using AppCompat at all - neither setting the properties nor using a custom view. When not using AppCompat both works as expected. The full source code is available here so just run the app if you're curious :) using System.ComponentModel; using Android.App; using Android.Widget; using App1.Droid.Renderers; using Xamarin.Forms; using Xamarin.Forms

问题 I want to link to my app from an e-mail. The Xamarin documentations describes how to link to an app: http://developer.xamarin.com/recipes/cross-platform/app-links/app-links-android/ However, it does that by referring to an additional component (Rivets) and it focuses on linking by code: Rivets.AppLinks.Navigator.Navigate("http://location/of/your/html/file.html"); and it requires to publish a page: Publish this page somewhere on the internet, or at a location your Android app can reach.

问题 I want to store development vs production connection strings and configuration strings in a monodroid project. I would normally store it as app settings in a web.config or an app.config, but how should I do it in monodroid and monotouch projects? I would also like for it to switch configurations automatically between debug and release builds just as visual studio does with *.config files. In an iOS app I could store these in a plist but I'd like a cross platform solution in mono. How would I

问题 I have an app with four pages, and I want it to look similar to my (non-Xamarin) iOS app, so to have toolbar at the bottom. Here is my MainPage.xaml file: <?xml version="1.0" encoding="utf-8" ?> <TabbedPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:local="clr-namespace:XaBLE1" x:Class="XaBLE1.MainPage" Title="Safe-T Sim" HeightRequest="768" WidthRequest="512" BarBackgroundColor="#F1F1F1" BarTextColor="Gray" xmlns:android="clr

问题 We are considering porting our C# .NET application to Android, and I have started reading about Xamarin.Android and the Mono framework. I am just beginning with Android development. I notice on the main http://xamarin.com/android page that it states: Native Code High-performance compiled code with full access to all the native APIs. Does this imply that the generated code will be native code that is more difficult to reverse engineer? We would like to create amongst other things a class

问题 I am working on extending number of supported platforms for my app, it used to support .NET4/Windows Store/Windows Phone, but I hope to also cover Mono for Android and iOS. I've put all business logic, models and view models to portable class libraries (PCL) but it's a big dilemma what subset of platforms I should target. Each combination causes something to fail. Here are the results for 4 platforms that I might use: Profile 78 (NET45+WP8+Store): no problem with TPL,await/async and support
