Inconsistent Deployment Errors

Nathan Sokalski 4,116

I am attempting to create a Xamarin.Android app using Visual Studio 2022 Version 17.1.0. I inconsistently (even if I have not changed any code or configuration) receive the following error:

There were deployment errors. Continue?

The Output window gives no useful information, so I have no idea where to look for more information on the problem. I have not found anything online that seems to help. I am having this problem on the following devices (and I probably would on others as well):

Emulator in Visual Studio 2022
Surface Duo
Samsung Galaxy S10e

What is the problem?

Hi, njsokalski. Try to factory reset the emulators or clean and rebuild the project. This may be a potential issue with the update of VS, it's suggested to report the issue to VS product team. Please see How to report a problem with Visual Studio - Visual Studio | Microsoft Learn

I am pretty sure the problem is not the emulator, because (as I mention above) it happens on my physical devices as well. I have tried cleaning & rebuilding the project, but that does not make any difference. I have not tried doing a factory reset on the emulator, although that is obviously not something I would want to do on my physical devices. I will take a look at reporting the problem, although it seems like a somewhat generic question, since I don't have a lot of detail to give.

Thanks for sharing the details. You could focus on the reporting thread for a solution.

I have reported the problem, and it (extremely recently) has been reported. However, it has a request for more information:

https://developercommunity.visualstudio.com/t/Xamarin-deplyoment-to-android-fails-sile/1672810

However, I have never used the Device Log Tool or Debug Log Tool. I have found the Device Log Tool, but I could not find the Debug Log Tool (is that the same thing?). But I also was not sure how to attach the device log. Is there a file somewhere? I found lots of stuff on how to open the tool, but nothing on how to send the results or where they are saved. Are there any good pages on how to do this? Thanks.

I have the same problem.

Reopen visual studio will temporarily suppress the problem but will reoccur after a while

If I restart visual studio, the problem will not happen for a while, below is the normal deploy output

I've just updated to 17.1.0 and am encountering the same issue. The only difference for me is that I get the deployment error, then I hit cancel and then run it again and it works. So for each build\deployment, I have to run it twice. This project worked successfully on a prior build (I cannot recollect the exact version I had prior to updating but it was something like 17.0.4/5 I believe)

Using VS2022 Enterprise 17.1.1, trying to deploy to Android 12 S emulator (app target and compile is also both Android 12), managed to fix by using Android SDK Command-line Tools (latest) 5.0 inside VS's Android SDKs and Tools window. If you open Android Device Manager in VS though, it will complain about that it can't find the command line tools - DO NOT ACCEPT THE PROMPT TO INSTALL THEM.

Did they solve this in 17.1.2 ? I have the community edition and the error is very annoying!
Nathan Sokalski 4,116 Reputation points

2022-03-23T19:03:55.913+00:00

I'm assuming this was intended to be a comment (not an answer), but either way I will say that I do not believe it is fixed, because I have also installed the 17.1.2 update and am using the Community Edition and still receive the error. If it is fixed (although I do not believe it is), then there is some configuration that is very messed up, and I would like to know what it is & how to fix it. Losing the ability to use certain features (such as Undo) between every debug session makes it very hard to experiment with code.

This really is annoying! VS 2022 Community 17.1.2 ... every time i need debug after some time trow this error.
I need then close and open VS every time.

Any luck by installing only the Android SDK Command-line Tools (latest) 5.0 inside VS's Android SDKs and Tools window?

Could you give more detail on exactly how to do what you suggest? I'm not sure what to do to install/uninstall/modify what you mention. I can obviously deny the request to install the command line tools, but what if they are already installed (I would guess they are, but I don't know for sure)? I don't know the exact details of my Android SDK installation, so I am not sure what I might need to change to solve this problem.

I have 2 command line tools at the SDK window, both are v5 and both are 104MB in size, but one of them is marked as "latest", which one should be ticked ?

Uncheck/uninstall the non latest one

In the menu bar: Tools -> Android -> 'Android SDK Manager', which will bring up a window. In there select the 'Tools' tab, and under 'Android SDK Tools' make sure only 'Android SDK Command-line Tools (latest)' is checked (you may need to expand the 'Name' column to see the full name). The other one needs to be unchecked and uninstalled.

After try, uncheck 5.0 and check 5.0(lastest), the problem persist.

In the output window, debug section, can see this

"Build Error: Xamarin.Android does not support running the previous version. Make sure the solution is compiled before running or debugging it."

Seems to be an issue with <queries> in the Android Manifest for me.

Same issue here as described by @Nathan Sokalski , and I get the same output as @Guanghua Xiong ! I have to restart visual studio for every debug session.

Just started noticing this problem today March 25th 2022, and I use VS everyday.

For me the problem started this morning when I added <queries> to my Android Manifest and added Xamarin.Essentials.Browser to my app.

If I remove those changes the app starts deploying fine again.

My manifest is pretty much lifted from the docs open-browser:

<?xml version="1.0" encoding="utf-8"?>  
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="25" android:versionName="3.1.4" package="com.foo.bar" android:installLocation="auto">  
	<queries>  
		<intent>  
			<action android:name="android.intent.action.VIEW" />  
			<data android:scheme="http"/>  
		</intent>  
		<intent>  
			<action android:name="android.intent.action.VIEW" />  
			<data android:scheme="https"/>  
		</intent>  
	</queries>  
	<uses-sdk android:minSdkVersion="23" android:targetSdkVersion="31" />  
	<application android:label="FOOBAR" android:allowBackup="false" android:extractNativeLibs="true"></application>  
	<uses-permission android:name="android.permission.CAMERA" />  
	<uses-permission ... et cetera  
</manifest>

Side note:
@Guanghua Xiong s project says BlueWifi. My project uses Bluetooth and Wifi. Is that the root of the problem?

I doubt that's my problem, because the only elements in my manifest file are uses-sdk & application (my app does not connect to the internet or use anything that requires special permissions like the camera or bluetooth).

I'm having the same issue with VS 17.1.2.
I have tried everything on-line and like the rest of the contributors here find myself having to restart VS. Some times it fails to go into debug mode as well :(

I was getting the same issues. I stopped the emulator and then factory reset it, then started it up. Then restarted the phone(not stopping the emulator, actual phone restart). Then I was able to deploy just fine

Why no official developer reply to this issue ? I have tried all the solutions posted here without any success, I have to close visual studio every 1 or 2 builds to be able to deploy!

@Max Payne , there is no official developer reply here because Q&A is not a bug reporting site and isn't watched by the development team.

You'll get the best results by reporting bugs via the official reporting paths. See How to report a problem with Visual Studio - Visual Studio | Microsoft Learn

Doing so will let you get notice of updates and provide more details on your specific issue. Often times when people post symptoms on forums instead of in the feedback site multiple issues get jumbled together and lost - you might have a similar symptom to somebody else's problem, but with a different cause so the fix to the original problem doesn't apply and your unreported problem doesn't get addressed. Note that multiple people on this thread have reported different symptoms and so may not all be running into the same problem.

From the Q&A How to write a quality question FAQ:
Don't use this site to report product bugs or feature requests .

This is a site for support, so please use the right site to requests new feature requests about a Microsoft product or report any bugs. This will ensure that the experts can focus on resolving user's problems instead of having to redirect you to the right site.

What is LTSC? Also, are you suggesting downgrading to the versions you mention?

Apparently is this, you can download specific version for enterprise y professional, community dont have.

Long term support version. Yes, until they fix bug. Better this than closing and reopening VS after every deployment (or cleaning bin and obj directories).
Here's the link about VS release rhythm: https://learn.microsoft.com/en-us/visualstudio/productinfo/release-rhythm.

Then downgrade to version it wokrs fine. I suggest you try 17.0.6 - February 8, 2022 - 17.0.32126.317

17.1.0 has the same bug

MJMC 6 Reputation points

2022-03-30T17:08:04.11+00:00

Its the best fix for now, but for me that i use Community version, LTSC don't work :( You say delete bin and obj folder work?

Dalibor Markovic 6 Reputation points

2022-03-31T05:15:11.463+00:00

you don't need to install LTSC, try with versions below 17.1.0 - I think 17.0.6 would work. Yes, deleting obj and bin helped me (in both Shared and Project), but the problem is that you need to delete them a couple of times because VS creates it just after you delete them. Since I have no time to waste I started with downgrading version until I found the one that works. I hope MAUI will have less bugs...

Nathan Sokalski 4,116 Reputation points

2022-03-31T15:58:09.473+00:00

you need to delete them a couple of times

How many times is "a couple of times"? If it recreates them just after you delete them, won't that just put you right back where you started from?

Dalibor Markovic 6 Reputation points

2022-04-01T05:34:16.01+00:00

no, it just recreates some of the files, but I suggest you downgrade VS to version that works, below 17.1.0

I have found the Device Log Tool, but I could not find the Debug Log Tool (is that the same thing?). But I also was not sure how to attach the device log.

Hi, njsokalski. Device Log is just the tool to get the log. For how to obtain the log, you could refer to the following doc:

I looked at that, but the post at

https://developercommunity.visualstudio.com/t/Xamarin-deplyoment-to-android-fails-sile/1672810#T-N1677097

says "attach the debug logs". What does that mean? The page you mention tells how to view the log in VS, but I don't know how to attach that. Is there some file? Is there some tool for attaching it?

You could create a text file. Then click Control + A to copy all the logs and paste the log to the created text file.
