@regisramillien can you paste the exact error message you're getting? A MSBuild diagnostic log would also help.

We fixed a few issues related to this, which is now available in the VS 15.9 preview. Could you try it and see if the problem goes away? You can install it side-by-side stable.

Same issue here. Happens sometimes and you have to clean, uninstall app on device before it works again.

jonathanpeppers commented 5 years ago

@SamuelDebruyn the build log (or if your willing to zip up/share the contents of your obj directory) would help more that what you are seeing at runtime.

In either case, @SamuelDebruyn do you think it could be related to the VS for Mac issue mentioned here?

Let's say you make a change to your project, in many cases you will see the notification area say Updating Resources.. or the Xamarin.Forms equivalent. (It might say Updating Xaml... or something?)

Currently, if you build (hit the play button) while this operation is happening, two msbuild's run at once, which can corrupt the obj directory. This issue is being worked on/tracked internally. This is not an issue on VS Windows, but hopefully this can be fixed in VS for Mac soon.

If it is random, this sounds like it could be the culprit?

sdebruyn commented 5 years ago

@jonathanpeppers I updated my comment with the buildlog :)

Could be, but not sure. @MaximST92 thinks it's related to actions in git.

MaximST92 commented 5 years ago

I think it has something to do with moving resources from one project to another project in the same solution.

jonathanpeppers commented 5 years ago

@MaximST92 so that sounds like something we should try.

Are you moving them from a Xamarin.Android library project to another library project?

MaximST92 commented 5 years ago

like this example: DroidProjectA resources to DroidProjectShared

sdebruyn commented 5 years ago

This is a mayor annoyance. 1 out of 5 builds fails with these kind of crashes. Sad to see you've marked this as "far future". Means that development with Xamarin.Android will be a PITA until the far future?

sdebruyn commented 5 years ago

@jonathanpeppers If you send me an email with your bitbucket username (sam.debruyn@3factr.be) I can give you access to our repo so that you can experience this yourself.

jonathanpeppers commented 5 years ago

@SamuelDebruyn I believe your issue is related to the VS for Mac issue mentioned here.

They have fixed this in VS for Mac 2019. The change is in a private repo, or I could link to it.

Do you have repro steps for what you are seeing? I can try a File -> New project first with the latest VS for Mac bits.

sdebruyn commented 5 years ago

I'm afraid I don't have a repro for this. I know it happens consistently about 1 out of 5 times on one of the projects I'm working on. Is the change available in the latest public version of VS 2019? I'll try that.

jonathanpeppers commented 5 years ago

Try it and let me know, it might be coming next preview, because they didn't fix it that long ago.

jonathanpeppers commented 5 years ago

@regisramillien / @SamuelDebruyn

Visual Studio for Mac 7.8 preview has a fix for an issue related to this: https://docs.microsoft.com/en-us/visualstudio/releasenotes/vs2017-mac-preview-relnotes#xamarinandroid-1

I've had one developer tell me their problems were solved when updating, let me know if that works for you!

jonathanpeppers commented 5 years ago

We have several fixes that I think address this:

These will be in a future VS 2019 Release (16.1, perhaps?)

Try out the VS 2019 previews and let me know if you folks are still hitting this, thanks!
