I used to create my apps using visual studio 2019 but for some reason I had to downgrade to vs 2017. my apps used to work properly and I had no problem compiling them on my physical device that has android 10 on it. now i'm getting an error when I open my old apps using vs 2017 that target framework version 9 is not supported. and when I try to create new apps, they won't run on my phone. I tried to change my target framework version but there is only versions up till android 6. i'm trying to install version 9 using the sdk manager but it's not working. I would like to know how to solve this issue. should I reinstall vs 2019. thanks in advance.
I attached a photo to show you what i'm doing to install api 29.
What is Xamarin version? I suspect that your version of Xamarin.Android is 6.x which means that you won't be able to target Android 7.0 or 7.1 even if they are installed through the SDK manager.
You can check the version from Help > About Microsoft Visual Studio.
If you're using Visual Studio 2017 or newer, Xamarin updates are delivered as part of Visual Studio updates. To manually check for updates, go to Tools > Extensions and Updates... In the left hand menu, open Updates and select Product Updates. If there are updates available, they will be shown on this list.
I have recently installed Win10, VS2017 Community and Xamarin Studio on my computer. My project is written in VS2017, and when I compile and run it on the device from VS2017 it all works fine, but when I open it in Xamarin studio, I get error "this project type requires Xamarin.Android to be installed". I installed monodevelop, gtk sharp, build tools fool. In Android SDK Manager I installed all I needed. Also, when I press "New solution" in Xamarin studio, it does not offer "Android project". None of the answers I found doesn't works for me. All of the above mentioned worked perfectly on Win7, except that that project was written in VS2015 Community! Need help. Thanks in advance!
I ran into this issue as well. I had been developing in Visual Studio 2017 and wanted to switch to Xamarin Studio for working on layouts, since the designer and AXML intellisense is so much better.
What I discovered is that I needed to install a seperate Xamarin.Android package. I downloaded it from this link https://store.xamarin.com/account/my/subscription/downloads. The universal installer didn't work for me; it only offered to install a remote iOS emulator, Xamarin Profiler, and Xamarin Workbooks, so I downloaded the separate installer and it cleared the issue up.
I came across this same error, and the search results brought me here. Unfortunately, the solutions above are now out of date.
I eventually solved my problem, by going to Preferences -> Projects -> SDK Locations -> Android. Where it immediately showed a popup "SDK needs repair". I had to leave it to download the necessary components.
FYI, Xamarin Studio is now Visual Studio for Mac.
I've started developing an IOS app with Xamarin. This is a screen of a scenelist in the storyboard in Xamarin studio. Can I also display this in Visualstudio 2015?:
thanks for help
The equivalent in Visual Studio is the WPF Tree Visualizer.
You can read more about how to use this here: https://blogs.msdn.microsoft.com/zainnab/2010/01/29/using-the-wpf-tree-visualizer/
I have windows 7 installed in my computer. I am trying to develop android application using visual studio community 2015 and xamarin.
But I am Getting an error while deploying.
I want to Know system requirements for developing android aaplication using visual studio 2015 community and xamarin.
Error while deploying is as below:-
Mono.AndroidTools.InstallFailedException: Failure [INSTALL_FAILED_NO_MATCHING_ABIS]
1> at Mono.AndroidTools.Internal.AdbOutputParsing.CheckInstallSuccess(String output, String packageName)
1> at Mono.AndroidTools.AndroidDevice.<>c__DisplayClass90_0.b__0(Task`1 t)
This error means that you're trying to install an application on a device which uses an architecture that isn't supported by a part of the application.
If you're using a very obscure device, Xamarin bundles several native libraries in every Xamarin.Android app and it's possible that one of those isn't compatible with your device.
Another possiblity is that you're using an emulator that uses "Intel" architecture. This might not be compatible with libraries designed for devices using the "ARM" architecture, most commonly found in phones and tablets. If that's the case, try using a different emulator.
I loaded Visual Studio Professional 2015
Version 14.0.25123.00 Update 2
Xamarin 4.0.3.214 (0dd817c)
Xamarin.Android 6.0.3.5 (a94a03b)
Xamarin.iOS 9.6.1.8 (3a25bf1)
However, when I bring up Visual Studio, the Tools/iOS menus items are disabled. The Android menu items ARE enabled.
Do you have installed Xamarin on a Mac and paired it to your Windows machine
Requirements & Installation
There are a few requirements that must be adhered to when developing for iOS in Visual Studio. As briefly mentioned in the overview, a Mac is required to compile IPA files, and applications cannot be deployed to a device without Apple’s certificates and code-signing tools. Also, the iOS simulator can be used only on a Mac.
Introduction to Xamarin.iOS for Visual Studio
Patience is a virtue. Eventually, the menu enabled itself while I was looking at a training video.
I got the same issue. When I installed Visual Studio 2017, first thing I did was to download an existing Xamarin project. When I checked the 'iOS' menu item in Tools it was all disabled.
After a restart of the system, I tried to create a new Cross Platform App (Xamarin). Once the solution is created, I got the following message and the iOS menu has Mac Agent option enabled.
