I installed Xamarin in Visual Studio 2015. Created New Project - Xamarin.Forms (Portable) and get error : A problem was encountered creating the sub project . This project required a Visual Studio update to load . Right-click on the project and chooes "Download Update" .
But there is not any "Download Update" .
How I can solve this problem ?
Open only the project that needs the update (not the solution) with VS. It should prompt you with what it needs and offer to install it.
It seems that you are working with the latest version of Xamarin, which now includes support for UWP apps. You can either install the Windows 10 SDK or simply delete the UWP project in case you are not interested in deploying your app to a Windows 10 device.

so , I am a programmer who is young , but developed some windows apps.
click on this to see my last app i developed.
and I want to learn android programming. i have downloaded the android studio but when i want to open a new project it says "your android SDK is corrupted or not downloaded"
can you solve this?
Go to SDK Manager uninstall and reinstall the SDK tools and platforms
I'm trying to follow this guide to install Visual Studio with the Android SDK manager:
Link to guide: https://learn.microsoft.com/en-us/xamarin/android/get-started/installation/android-emulator/hardware-acceleration?pivots=windows
So I downloaded Visual Studio from here: https://visualstudio.microsoft.com/vs/
After installation, the menu Tools > Android > Android SDK Manager is not available.
What should be done to make the menu available? And be able to open the Android SDK Manager?
using Visual Studio 2019:
You will need to run the "Visual Studio Installer" again. Then click modify, and in the Workloads tab, select:
Mobile development with .NET.
Build cross-platform applications for iOS, Android or Windows using Xamarin
The Android SDK manager will be available after you've installed this workload.
You could try to run VS as an administrator, which resolves almost any issue of the kind you are experiencing right now.
Another free advice before you start: if you find any problem building(even when you start VS as admin), first try to delete your \bin and \obj folders and try again. That is the solution to 99% of the issues.
I downloaded a fresh copy of Visual Studio 2019 Community Edition. For installation, I selected only the Xamarin workload for mobile development. I created a new Xamarin.Forms project and it immediately gives the following error:
When I double click the message, I am prompted to Accept the Android SDK License Agreement. I click accept, and nothing changes, I just keep repeating those steps.
Navigating to the Android SDK Manager shows an empty list with an error:
All the solutions I have found online have not worked for me:
Enable "Auto-Install Android SDKs" in Xamarin options
Run Visual Studio as Administrator
Create custom AndroidSdkManager.exe.config file
Uninstall and re-install Visual Studio
Verified JAVA_HOME variable is set correctly
The only thing that resolved the error (before I uninstalled) was changing the Android SDK Manager repository from Microsoft to Google:
This doesn't seem like a proper solution given the warning message shown so I am wondering what else I can do.
If this issue has not been resolved yet, try to:
Open Visual Studio as an admin because the software might be failing to read the files in your system.
Go to Visual Studio > Tools > Android > Android SDK Manager and go to the tools tab and install Android SDK Command Line tools.
Then now, you can double click on the error and the issue should be resolved.
I'm running VS2022 17.4.2 and the same issue appeared on a new 7.0 Maui Blazor App. Closing VS and Running as Administrator, reopening the project, then clicking on the error gave me a License Acceptance. After accepting, all is well.
I was running on Windows 7. The issue was resolved after upgrading to Windows 10 and the Android SDKs installed correctly.
NOTICE: I found other questions and answers about the same issue, but the answers are for older versions of Android Studio, and I want confirmation if it still can work for the latest version of Android Studio (2.2.3.0 which was released on December 6, 2016)
I'm new to the Android development and I selected the IDE to use wrongly and before thinking and knowing which IDE to use.
So after this mistake, I must use Android Studio now to use the GRADLE libraries as Eclipse doesn't officialy support them (because Eclipse is now discontinued).
The Android Studio is 1.63 GB (including the Android SDK), while Android Studio is 417 MB (without the Android SDK).
I have Android SDK Tools R25.2.3 ( latest ) already downloaded, so I don't want to download the whole Studio + The Android SDK again.
Is it possible to download the Android Studio without the SDK, then link the SDK to the Studio manually?
I'd be very thankful if someone could help!
Yes it is possible , Studio and SDK can been seen as separate components and they can be linked by providing SDK path in the studio IDE or you can configure you SDK path thorough the setting menu shown at the start screen of android studio.
You can download the standalone IDE through Official Android Studio site.
Note : http://tools.android.com/ has dropped the support of providing separate SDK and IDE components but still IDE can be downloaded individually from Android Official Download Link
Steps to configure after download
1.) Download and Extract the IDE
2.) Find studio or studio64 exe and run the appropriate one in your OS
3.) When you start your studio , it will probably ask for SDK location through a prompt screen and provide the location and hit next and next , eventually it will show you a little process for update window and show you finish screen (Must follow the note below)
3.a) If there was no prompt screen shown then you can configure the SDK path using the setting option on the Splash screen of android studio
3.b) It's possible that when you open an old studio project and SDKis still not configured because every project has it's own setting so again you can see the link in error/log window as configure SDK and just click the link and provide path
Note : Disable internet before configuring you studio otherwise it will look for Updates
Helpful points to possible issue
For old project , replace the old dependencies with the one you have in project structure link for Visual representation of steps
Replace the gradle version with the one supported by your new studio and do the same if any other tool is not found.
Definitely. The Android Studio IDE prompts you to specify the path containing the Android SDK tools, if it doesn't detect the SDK automatically.
I just downloaded xamarin studio. I get an error message "disconnected from layout renderer please close the file and try again" whenever i open a axml in the layout folder. I can view the source but can't go to the design tab to add controls. Closing the filed does not work.
I'm not sure how to find what version of xamarin.android i'm using but I just downloaded last night. When I go to the SDK manager it tells me my Android SDK Tools are version 23.0.4.
I found this old thread on the same topic. I tried renaming my tools folder and downgrading but that didnt' work either. It told me I need tools of at least version 22.

I've tried uninstalling Xamarin Studio and reinstalling and that didn't help. I do have Visual Studio 2013 with update 3 installed too. But then I also tried installing Xamarin Studio on another laptop with Visual Studio 2012 and got the exact same problem.
Note: this error displays in both Visual Studio and Xamarin Studio.
I really hope I can get this resolved as i'm evaluating Xamarin for 2 companies. Any help is greatly appreciated.

Only this time, you need to downgrade from 23.0.4 to 23.0.2.
Just found this out the hard way.

Thank you Balint! You made my weekend!!! Here is a direct link to the tools version that works.

I recently had this same issue when trying to open the main.xaml in Xamarin Studio for Mac OS X. Here are the steps I took to resolve the problem:
Open the Android SDK Manager in Xamarin Studio and delete the Android SDK Tools.
Re-download the SDK Tools from [https://developer.android.com/sdk/index.html?hl=i]. Revision 23.0.2
Make sure the downloaded SDK is unzipped in the path /Users/username/Library/Developer/Xamarin/android-sdk-macosx
Then I launched the SDK Manager from the Terminal using cd library/developer/xamarin/android-sdk-macosx/tools ./android
When the SDK launches, make sure the Android SDK Tools is not selected, else it will update it to 23.0.5 which appears to currently be broken.
After the SDK Manager updates and installs all the packages, re-open Xamarin Studio and go to Preferences -> SDK Locations -> Android and chose the path for the Android SDK.
After following these steps I was able to successfully open the main.xaml files for Android on OS X.
