Xamarin - The project is missing Android SDKs required for building - android

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.

Can't install vsix to Visual Studio 2019 - Android Device Manager has a lower version than required by Visual Studio

I have Visual Studio 2019 installed with Xamarin. I'm trying to get Shell to show up in the project templates. I'm following this post as a guide. But when I install the vsix file, it fails with the error message: Installation of Microsoft.VisualStudio.Android.DeviceManager failed. The extension has a lower version than required by Visual Studio. Please install the extension from Visual Studio Installer instead.
Where in the Visual Studio Installer is the Android Device Manager? I've installed all the Mobile Development tools and all updates....
That post is obsolete - it describes something you needed to do in a Preview version of VS 2019.
In VS Installer, select Workload "Mobile development with .NET".
I was unable to find any Microsoft doc that tells you to simply do that!
I don't recall whether you still need to also do this step:
Setting up the Android SDK for Xamarin.Android.
After installing the Workload mentioned above, restart VS. See if the menu item mentioned below is there. If so, try to make a sample app - maybe this "Android SDK" step is no longer needed - the Workload might set everything up.
Then Android Device Manager will be at menu Tools / Android / Android Device Manager.
Menu location documented here.

How to fix android studio first run issues?

I installed android-studio and android-sdk from terminal in Ubuntu groovy gorilla. Now whenever I start android studio it shows an error stating:
"unable to access andrid-sdk add on list"
The changes that I make in set proxy do not work.
So I clicked cancel and then in the welcome page it shows that :
"android studio sdk is missing or corrupted."
Then I when I open the sdk manager, it tells:
"nothing to show"
PS: Android studio worked fine before I reinstalled Ubuntu.
Try installing Android Studio from Official website or JetBrains Toolbox app.
And don't try to install android sdk and other tools like gradle manually. Leave it Android Studio install them for you. If possible don't use proxy. Because it requires you additional settings. But if you use proxy please refer to this link for setting proxy in Android Studio

Unable to update SDK components within Android Studio 2.1.1

So when I opened Android Studio today, there was a notification telling me that there is an update available for the Android Support Repository. I clicked on the update link and I received this warning:
Due to your system configuration and the packages to be installed, it
is likely that the following packages cannot be successfully installed
while Android Studio is running.
Please exit and install the following packages using the standalone
SDK manager:
-Android Support Repository
I went in the Android SDK settings page and it gave me the same result when clicking Apply.
My SDK is in C:\Android\sdk\ so it can't be a problem with rights elevation. I had the SDK installed before I installed Android Studio, however I had some problems with the SDK so I completely flushed and reinstalled it, while Android Studio was installed.
I also used the edit link next to the path (in the Android SDK settings) and I went through the setup, Android Studio found everything and had nothing to do. There was an update for the latest platform which I did through that instead and Android Studio installed it properly without needing the standalone manager.
Is it just that this component must be updated from the standalone manager or is it a problem with my Android Studio and/or the standalone manager?
UPDATE: I have tried to update from the main menu (after closing the active project) and it still asks me to open the standalone.
To be clear: I can update properly from the standalone SDK manager and there is no problem with opening it, however I have seen a clean install on a colleague's computer and he could install additional components directly inside Android Studio without using the standalone manager at all, so I find it quite annoying to close, update and reopen when I shouldn't have to.
Should I risk to attempt the update from Android Studio (as there is a button for it), reinstall or repair Android Studio or do I need to flush absolutely everything and install from scratch?
I'm not totally sure if this will help but - try uninstalling everything to do with android studio (the ide, sdk, etc.). Also delete every file they created on your computer.
Did you download the 1.2 GB android studio all in one? If not, make sure to grab that one.
Also, make sure your Java SDK is also installed and that your Windows environment variable points to the sdk location correctly.
Finally, you do have to exit android studio in order for the sdk standalone to work properly.
Hope this helps, good luck.

Xamarin - disconnected from layout renderer

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.
http://forums.xamarin.com/discussion/14344/disconnected-from-layout-renderer-error-after-updating-android-sdk-tools-to-version-22-6
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.
Cheers
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.

No Android SDK found - Android Studio

I have a problem with Android 0.4.2 Studio, when creating a new application, it tells me there is a problem with the rendering and shows me the following problem:
Renderering Problems
No Android SDK found. Please configure an Android SDK.
My setup SDK and JDK is this: Android SDK location: C:\adt-bundle-windows\sdk, I put the path I use in Eclipse SDK, or there may be the problem, if someone has happened and what has been fixed, I'd like to give me the solution, thank you very much.
I just encountered and solve a similar problem.
First you should check the directory like other threads described. Then you can check whether the Build tool version matches your SDK version.
(e.g. for my project, in build.gradle file, you have:)
android {
compileSdkVersion 21
buildToolsVersion "21.1.1" }
and then open you SDK manager, make sure you have the same version of sdk(21.1.1) installed in the selected directoriy:
If not, install it and restart Android Studio. It works for me.
I've also seen other guys saying run Android Studio as administrator would also help:
https://teamtreehouse.com/forum/i-am-getting-this-warning-message-rendering-problems-no-android-sdk-found-please-configure-an-android-sdk
I got the same "No Android SDK Found" error message... plus no rendering for Design window, no little cellphone screen.
My SDK path was correct, pointing to where the (downloaded during setup) SDK lives.
During Setup of the SDK Mgr, I didn't download the latest "preview edition (version 20)"...(I thought it better to use the next most recent version (19)) Later I found, there was no dropdown choice in the AVD Manager to pick Version 19, only the default value of the preview, 20.
I thought "Maybe the rendering was based on a version that wasn't present yet." So, I downloaded all the "preview edition's (version 20)" SDK Platform (2) and system images (4)...
Once download/install completed,
RESTARTED Android Studio and Viola! success... error message gone, rendering ok.
From the File menu, choose Project Structure (if you're running 0.4.4 there's a bug and the menu item doesn't have a title, but it still works), and choose the Android SDK item. You should see something like this where you can set up your JDK and SDK.
After setting it, quit Android Studio and relaunch it for good measure.
i have just discovered, android studio 3.0.1 has no sdk during the installation. because during the installation, it doesn't give sdk as part of install able unlike in recent versions of android studio.
Don't worry just change the
build.gradle
ext.kotlin_version = '1.2.41'
to previous version.
It worked for me hope it works for you too.
Happy coding.
According to the Android Studio download page, the SDK comes bundled with Android Studio. It has its own copy when you install Android Studio.
ADT is a plugin for Eclipse. Try reading through that webpage to see if there is something that got missed when installing.
Here is the wording from the site, regarding ADT:
Similar to Eclipse with the ADT Plugin, Android Studio provides integrated Android developer tools for development and debugging.
I wanted to share a part of the issue I had because it is the first google result.
I installed Android Studio, when I tried to install my first SDK from the SDK Management windows I got the error that I didn't have any SDK installed.
I tried to look on the internet to manually download the .zip,manualy create the folder, no luck what so ever.
When I tried to run the Android Studio as an administrator it detected I didn't have any SDK and prompt me right away at startup to download a SDK.
Do following steps
a) Change minSdkVersion and sync gradle
b) Revert back your minSdkVersion and sync gradle again
It will be resolved.
These days, Android Studio setup do not provide SDK as the part of original package.
In the context of windows, when you start Android Studio 1.3.1, you see the error message saying no sdk found. You just have to proceed and provide the path where sdk can be downloaded. And you are done.
Here is the solution just copy your SDK Manager.exe file at the root folder of your android studio's installation, Sync your project and cheers... here is the link for details.
running Android Studio on Windows 7 fails, no Android SDK found
Try make New Project, and then choose same android version that you've installed sdk verions on "Target Android Device" dialog.
In my case, error message gone.
I had the same problem, Android Studio just could not identify the android-sdk folder. All I did was to uninstall and reinstall android studio, and this time it actually identified the folder. Hope it also works out for you.
Download android sdk through this sdk manager https://dl.google.com/android/repository/tools_r25.2.3-macosx.zip
(note this link is for mac)
open android studio, click next, open where it ask to add path where u downloaded sdk..... add it... click next, it will downloaad updates..... and it done
Right now, the last version of Android Studio bundled (Windows IDE bundle with SDK (64-bit)) with Android SDK is version 2.3.3:
https://developer.android.com/studio/archive.html#android-studio-2-3-3
which size is about 2GB.
You can use it and then upgrade to the latest version of Android Studio.
I am on Mac Os. In my case, my host file was black. I added following entries (these entries should be there by default, but they weren't).
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
After re-running android studio, it prompted the sdk download.
I fixed this bug changing the proxy configuration:
No proxy → Auto-detect proxy settings
