Expected Behavior

The app is built and deployed to the device

Actual Behavior

The app is built but the deployment step fails with FastDeploy.DeployFileWithFastDevTool failure:

So the workaround target does work

Removed Item(s): _ResolvedSymbols=obj\Debug\100\android\assets\Zambezi.dll.mdb

But the format of the command is missing files like Microsoft.IdentityModel.Clients.ActiveDirectory.dll.mdb because of the multiple periods. A new target which handles this scenario is below.

<Target Name="_RemoveMdbFiles" BeforeTargets="_Upload">
    <ItemGroup>
        <_Temp Include="%(_ResolvedSymbols.Identity)" Condition="'%(_ResolvedSymbols.Extension)' == '.mdb'" />
        <_ResolvedSymbols Remove="@(_Temp)"/>
    </ItemGroup>
</Target>

Should be fixed by https://github.com/xamarin/monodroid/pull/1166

Oh good, because I have the same problem with almost every nuget package I use. Your link is not working though?

TomBruyneel on 19 Feb 2021

The link is to a private repo.
The best workaround is to upgrade your nuget package. The reason it happens is there are some old nugets still using the old pdb format. These have to be converted to mdb files for the debugger to use them. All of the new projects should be using the portable pdb format which the native runtime has built in support for. So if you can upgrade the problem packages.

dellis1972 on 19 Feb 2021

I already submitted a PR to Acr.UserDialogs to change PDB to portable and this is already merged. So use last nuget and be happy

This workaround has been replaced with https://github.com/xamarin/xamarin-android/issues/5631#issuecomment-794289675

dellis1972 on 24 Feb 2021

The fix for this was merged and included in this bump https://github.com/xamarin/xamarin-android/pull/5645. It should be in d16-10 P2. Please reopen if you find a case where none of the workarounds work.

dellis1972 on 24 Feb 2021

A workaround for people who cannot get an updated nuget package to fix the issue
<Target Name="_RemoveMdbFiles" BeforeTargets="_Upload">
    <ItemGroup>
        <_ResolvedSymbols Remove="**/*.dll.mdb" />
    </ItemGroup>
</Target>
add this to the bottom of your csproj just above the </Project> element.

Tried this, but still getting the same issue. with Xamarin.Auth.dll.mdb

Tried this, but still getting the same issue. with Xamarin.Auth.dll.mdb

I think this lib is dead. Check if Xamarin.Essentials has the API you need or fork the lib and change debug type on your own

MagicAndre1981 on 9 Mar 2021

@dileep-maxpro do you have a diagnostic build log we can take a look at? The best way to get one is via

msbuild <your Android csproj> /restore /t:Install /bl /p:_FastDeploymentDiagnosticLogging=true

That should produce a msbuild.binlog file. You can then zip this up and attach it to this Issue.

This unfortunately didn't work for me. It apparently compiles but I'm getting this when I attempt to deploy:

Could not find file '<project path>\obj\Debug\100\android\assets\Microsoft.IdentityModel.Clients.ActiveDirectory.dll.mdb'.

Attempting to run the above msbuild command failed with the same error and a build log that I have attached. I'm not directly referencing this package anywhere as far as I can see.

I am having the exact same issue as @louisoftokyo.

@dan-SLT

can you provide the diagnostic output using the command outlined in https://github.com/xamarin/xamarin-android/issues/5631#issuecomment-793708205.

dellis1972 on 9 Mar 2021

@dan-SLT

can you provide the diagnostic output using the command outlined in #5631 (comment).

Running what you requested I get the errors below.

MSBUILD : error MSB1005: Specify a property and its value.
Switch: /p:

MSBUILD : error MSB1008: Only one project can be specified.
Switch: _FastDeploymentDiagnosticLogging=true

dan-SLT on 9 Mar 2021

@dan-SLT

There was a typo in the command there was a space between /p: and _FastDeploymentDiagnosticLogging=true.
The actual command is.

msbuild <your Android csproj> /restore /t:Install /bl /p:_FastDeploymentDiagnosticLogging=true

This now worked for me. Thank you very much.

@dellis1972 Sure shall share when I run again. for now I unchecked the fast deployment and continue working for now.

dileep-maxpro on 10 Mar 2021

I reverted to Visual Studio 16.8.6 and re installed some Android SDK packages and it appears to be working. I was running Visual Studio 16.9.1 previously.

I have same issue as @dan-SLT
