I have a problem in my visual studio for mac, that prevents me from building android apps.
As you can see in the screenshots I can't even select an android SDK.
And my project tells me that Xamarin.Android is not installed.
I already tried reinstalling VisualStudio and Xamarin.Android but didn't helped.
Does anyone knows whether there is a cache or config file or something else that is maybe wrong and not correctly updated?
Launch Visual Studio for Mac and open the Extension Manager (App Menu / Extensions) and make sure that the Android extensions/addins are enabled:
If they are, check the IDE logs for errors related those extensions:
Help / Open Log Directory
AndroidTools.XXXXXXXX.log
and
Ide.XXXXXXXX.log

I built a Xamarin simple app project for android device.
It's compiled and also run on my device, whereas after some times I faced an error.
the error is:
"This project needs to be migrated."
and also I couldn't create new android Xamarin project.
In fact, it's disappeared from new project section.
What can I do??
My issue was that "Mobile development with .NET" was not selected/installed in the Visual Studio Installer for VS2019 (coulda sworn I selected that when I moved from 2017 to 2019, but whatever). Once selected and installed, the migration warnings disappeared and I could run the projects.
I had this issue when running the visual studio in safe mode, suggesting that an extension is disabled/missing.
I cannot hit a breakpoint in VS when debugging any native iOS app through VS2017 Pro. I have trawled the Xamarin/Stack forums and seen this has been a problem in the past and I have tried the suggestions but they relate to a 3.xxx version of Xamarin. Even an out-the-box new project untouched except for placing a breakpoint still does not hit, the build server pops up the simulator and runs as expected. Android is fine
This was working, I have recently downgraded from Enterprise to Pro but think this may be a red herring. I have 2015/13 pro installed with the same problem.
Is this an issue build server side or the windows side? I get the following generated in my bin App.app, App.exe, App.pdb but no app.mdb i do get the referenced dll.mdb files.

See this similar answer: Xamarin iOS debugger not hitting breakpoints
Also, make sure you don't have a firewall blocking Port 10000.
I ran into something similar, and it turns out my debug settings for my physical device had some defaults that prevented debugging from working. This may not fix your issue, but you might want to at least check your project settings for a few things.
Under iOS Build I changed my Linker Behavior from Link All to Link Framework SDKs Only. Also, for some reason in a default debug profile, the Strip native debugging symbols option on that same page was checked. Make sure it's unchecked.
This one was already enabled for me but you should verify anyway: double check that on the page iOS Debug that Enable Debugging is checked.
I faced a similar issue but on Android application: I solved by uncheck the option "Code Optimization" from Project >> Options >> Build and set the DebugType to Full
Same here, windows 10, VS 2017 -> MAC -> iPhone
Somtimes I got Debug-Log and can hit breakpoints but mostly not.
A solution / workaround which at least works for me.
Problem:
Setup: Windows 10 with VS2017, Mac-Book, iPhone connected to Mac-Book.
Debug-Log / Breakpoint-Hitting seams to work sometimes (seldom) / non deterministic.
Solution / workaround:
Verify: In case no Debug-Log occurs (e.g. no "Loaded assembly:..." lines etc.) the "Choose Device" drop-down box in the "Tools >> iOS >> Device Log" window shows TWO times the name of the iOS-device.
Stop the debug and explicitly stop the app on the iOS-device (if necessary also delete it for re-deploy)
Via "Tools >> iOS >> Xamarin Agent" disconnect from your Mac and then reconnect again.
Verify: the "Choose Device" drop-down in the "Tools >> iOS >> Device Log" window now shows only ONE times the name of the iOS-device.
Debug the App - it now should work.

Hope it also works for you.

I've installed Xamarin and tried in Visual Studio to start with a small app and test the web view with this. So for this, I've installed the JDK, the Android SDK and Android NDK on my computer. I'm working throught a tutorial for a web view and I have the problem, when I run the Main.axml, it shows me the error, that my Android SDK could not be found (look at the first attachement). When I check my location paths for the JDK, SDK and NDK, it shows me the correct path and a green tick, so the path and files are correct (look at the second attachement). But my app don't recognize it. What's the problem here? I found some threads on stackoverflow for the same problem, but nothing helped me.
1. Attachement
2. Attachement
OS: Windows 8.1
IDE: MS Visual Studio 14.0.23
Xamarin: 4.2.0
EDIT:
I also tried to open my Android SDK Manager, but this one is disabled in my visual studio. I've installed Xamarin, so it should work:
Any ideas? Thanks.
I tried so many things and finally I have the solution for my problem:
Possible reason for the problem: I just installed the Xamarin, which installes also the JDK, Android SKD and Android NDK in it's wizzard, so I thought this should be the correct versions. After installing Xamarin, I opened my Visual Studio and checked the paths (Tool - Options - Xamarin - Android seetings) for my JDK, SDK and NDK. The paths show on the versions, which were installed by Xamarin. My Android SDK Manager was disabled.
Solution: Then I uninstall everything - the JDK, SDK and NDK and also the whole Xamarin and my old Android Studio. After that, I decided to install the newest JDK from the Java website, the newes Android SDK/NDK from the Android Studio website and a plane xamarin without the sdk/jdk installation. So I could be sure, that I have the correct versions. After the installation, I again opened Visual Studio - Tool - Options - Android seetings and set the paths to the new versions. Than I checked my Android SDK Manager and it was finally enabled and so I installed also the newest Android SDK Tools. After that I cleaned and builded my solution, start it and my android emulator opens my webview page. So I think, the best way is to install the required programms from their website and not automaticlly with xamarin. Now it works. Cheers.
Apparently this is not a problem and someone proposed a solution that apparently works on Windows, this issue still exists on Mac.
Although the SDK installed by Android Studio on its default path (/Users/user/Library/Android) exists, Xamarin installer still wants to download a "private copy of android sdk":
Does anybody know a workaround?
I had this same issue. You can either add the path to the downloaded SDK by clicking the + button, or create folders in the default Xamarin location and then copy the sdk there.
Even though I tried this, a new Android SDK had just been released. The Xamarin installer was intent on downloading the latest version though, and I eventually ended up leaving it to complete.
I was able to change the Android SDK Location in Xamarin Studio to use what was already installed on my mac:
Xamarin Studio top right menu
Xamarin Studio Community
Preferences
SDK Locations
Android
Android SDK Location : Browse and choose the location of your android install; it's usually at the following location on a mac -> user/Library/Android/sdk
I am 100% new to Xamarin seem to have done something wrong in Visual Studio 2015. I am just trying to view my Main.axml file however the designer is giving me the following error:
A valid Android SDK could not be found. An existing SDK with platform tool and at least one platform needs to be registered with the IDE.
Do I need to do soemthing specific to fix this?
As you can see I am targeting Android 4.1 API 16.
Another weird issue is that the Android SDK Manager is disabled is this normal?
visual studio -> tools ->options:
To launch Android SDK Manager I have to launch Android studio and click on Android SDK Manager :
I had same issue with my sdk on visual studio. I could not open sdk manager from visual studio and xamarin designer could not open even though i pointed to an sdk location. however, other things worked correctly. Updating sdk from android studio and upgrading jdk to 1.8.0_102. solved my problem.
While the Xamarin is updating, that error can see.
Solved is found the tools zip file:
C:\Users\User Name\AppData\Local\Android\android-sdk\temp\tools_r25.2.4-windows (or your active last tools, doesnt matter. for ex. tools_r23.0.1)
-> Open that zip and unzip in "tools" folder.
-> Cut that folder and, paste parent folder (C:\Users\User Name\AppData\Local\Android\android-sdk)
Delete files from this path:
C:\Users\ ++ Your Windows Account Here ++ \AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache\
