问题 I recently got into Xamarin development. I have a lot of experience in Xcode making iOS apps and the iOS side was very straight forward. Now I'm trying to implement Android. I downloaded a Hello World example to get my bearings. When I run it I have no problems getting the simulator to show up ( MonoForAndroid_API_10 and MonoForAndroid_API_12 ) but the actual application doesn't run, and does not show up anywhere on the simulator. Essentially whenever I use run or run with in Xamarin on

问题 I want to find out if there is any good ideas/tutorials on how to add loading gif to an android layout when processing happens and when a page layout navigates to another page layout. I have tried using this - AndHud But it seems like it doesn't work well with Portal Class Librarys (PCL) and services inside the PCL. I couldn't find a lot of examples with this component. I see android uses a progress dialog for this but I was hoping for a Xamarin version in C# or any other clever way of doing

问题 I want to bind HoloEverywhere in Xamarin. The HoloEverywhere binary is a .aar file. It seems that if I mark it as InputJar, nothing happens in the Java Library binding project. So is there a way to make it work? 回答1: To bind to an .aar , the build action must be LibraryProjectZip . http://docs.xamarin.com/releases/android/xamarin.android_4/xamarin.android_4.7/#Xamarin.Android_4.7.10. 来源： https://stackoverflow.com/questions/23318859/how-to-bind-aar-file-in-xamarin-with-visual-studio-xamarin

问题 I'm building some code with these portable class libraries at present. I'm looking to target full .Net, WinRT Metro, Windows Phone, ... and then MonoTouch and MonoDroid. My experiments today show this can work - http://slodge.blogspot.co.uk/2012/04/experiments-with-portable-class.html However, I have hit a fairly significant problem - MonoTouch and MonoDroid currently support these libraries in that you can consume PCLs as binary assemblies, but they don't allow linking between project files

问题 I want to know how to create a Xamarin.Forms Project that targets minimum version of Android Kitkat (API 19), without using the Shared Project option. .Net Standard Library is not an option since the minimum supported Android version is Nougat. A large percentage of my target users (more than 40%) still uses phones with an Android version lower than Nougat. In Visual Studio 15.5.1 or greater, no PCL option is provided under the Code Sharing Strategy Section in creating a new Xamarin.Forms

问题 Currently working on a project where I want to use AppCompat and have a requirement setting title and subtitle on most of the pages. 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
