Hi @Universal Camera ,I did a test but I couldn't reproduce this problem. You can try to restart you PC and visual studio, and try again.

Thanks for looking...

So I did recent update on both Windows and VS2019. Prior to this I have an old application that is a working application. But after upgrade the old application fail to deploy.

So I created a new App1 with CrossPlatform Xamarin.Forms. Did Nuget Updates which there were none and then deployed to Android 10 Mobile Device. This was successful.

I then installed through Nuget Xam.Plugins.Messaging as a reference in only PCL and Android. Try to deploy it to same device and it failed.

I then deleted both reference (PCL and Android) and tried to deploy to same device and it was successful.

I then tried including various version of Xam. The versions 3.2.1 or lower deploy successfully. But I need higher then 4.0.0 since earlier version does not support Settings().

Thanks

So the outlined steps are for VS2019 Community.

How do I restore VS to previous build?

I really need my App back on my device. Do you have suggestions?

Sorry,I couldn't find the steps you posted.

You can try to delete bin and obj folders, then restart VS and try again .

Could you please post a basic demo to github or onedriver so that we can test on our side?

There is really nothing to post. I am creating a brand new App1 in VS2019 Community 16.9.1.
This new App1 compiles and successfully deploys to Android 11 Phone.
However if I just add a just a reference to Xam.Plugins.Messaging then it compiles but does not Deploy to device with error

The Process cannot access file ...\Plugins.Messaging.pdb because it is being used by another process...

And the nugets in my app is:

Good effort. When I match your GIT I get the same "Busy Process" issue.

However if you use the latest GIT and put VS2019 into Release mode then it deploys. However, Android 11 does not turn on the speakerphone. But, Android 10 does turn on the speakerphone.

I think you have done a good job to show the team that there is a problem in deployment and most importantly in the AudioManager for turning on the speakerphone.

I will look forward to you!

Do you mean you have resolved this problem by putting your app to github and set VS to Release mode,right ? Congrats. For the new problem , we can talk it in another thread: https://learn.microsoft.com/en-us/answers/questions/312067/speakerphone-not-responding-on-android-11-but-resp.html

Sorry for confusion...rather than compiling it under Debug mode in VS2019 where it doesn't deploy I put it into Release mode and now it deploys. This does not allow me to debug the code.

But the biggest problem persist with speaker phone.

Can you recommend another way to turns-on the speakerphone in Android 11. The above code turns-on the Speakerphone in Android 10.

Hi @Universal Camera , if we check link Xam.Plugins.Messaging ,we will find that nuget Xam.Plugins.Messaging hasn't been updated for a long time. So we don't recommend you to use Xam.Plugins.Messaging. And we recommend you use Xamarin.Essentials, which includes the features you need above. You can check it here: https://learn.microsoft.com/en-us/xamarin/essentials/phone-dialer?context=xamarin%2Fandroid&tabs=android

So based on your suggestion Plugin.Messaging is not working. Xamarin.Essential does not have AutoDial=true option while Plugin does therefore it really would be nice to fix Plugin.Messaging library.

I have a production app in the stores this is now happening to as well after upgrading to VS 16.9.2.

Release mode does not fix it either.

Since we now have >1 confirmed report caused can someone from MS suggest a workaround since we have narrowed this down to the VS upgrade?

Upgrading to Xam.Essentials is not an option at the moment for us as well.

Any ideas?

After upgrade AudioManager does not turn on SpeakerPhone on Android 11 phone. However, after the upgrade AudioManager still turn on SpeakerPhone on Android 10.

Only the Xamarin app.

We only have one Xamarin app that uses Plugin.Messaging, but all other projects:

WebAPI

pure desktop & mobile dotNet support libraries

WinForms with and without ADO

straight up .aspx style web apps

apps with Entity Framework (Core and .NET Framework style, Web and Desktop)

All compile and deploy fine.

There is something about the Nuget. I removed the package and commented out all code referencing it. It built and released just fine.

Do you any idea the time line for AudioManager fix. Is there another way to turn-on speakerphone during phone call besides AudioManager.

I have written alternative solution to Xam.Plugin so that issue is not impacting me.

Thank you
