Integrated new Google Places API and using directives not being recognized anymore

Question

Integrated new Google Places API and using directives not being recognized anymore

StevenSquires-9060 21

I had a working base of code. I replaced the deprecated Places SDK for Android with the updated new Places API. To do this, I had to uninstall Places SDK related nuget packages with Places API nuget packages. Now my nuget package using directives are not being recognized at all (creating a myriad of errors in my code base). How do I get my using directives to be recognized again?

I have included a screen shot and the Xamarin Diagnostics Debug Log.

Thank you for any help possible in advance!

Hi, StevenSquires-9060. Please check the dependencies of the Places API nuget package and make sure the required dependencies have been added. And try to emtry the bin and obj folder of the project, then clean and rebuild.

This may be a ridiculous question, but how do I check that the dependencies of the Places API have been added? They are not in my .csproj file. Is there somewhere else I should be looking? They also are not in my installed list of nuget packages in nuget package manager. I have uninstalled and reinstalled the nuget packages such as Firebase and Google Places API a bunch of times, deleted the bin and obj folders, cleaned the solution a bunch of times and still the Google Places API and Firebase nugets are not being recognized.

For example, if the nuget requires Xamarin.AndroidX.* packages, please migrate the project to AndroidX. What's the target version of your project? It requires AndroidX library since Android 10.

Could it be because there is no ProjectReference in my .csproj file?

OK JarvanZhang-MSFT - I did what you said and checked and installed every nuget dependency that was not installed when I originally installed the xamarin.google.android.places nuget. That seems to have fixed a lot of the problems except for the: The referenced component 'System.Core, System.Xml, Mono.Android, System.Numerics.Vectors, System.Numerics, System' could not be found (yet they are in my .csproj file). Removing the bin and obj folders and cleaning the solution does not seem to help.

Any other ideas for how to fix this would be helpful and keep my project on track.

Thanks for what you've already helped with though.

Hello,

Welcome to our Microsoft Q&A platform!

The referenced component 'System.Core, System.Xml, Mono.Android, System.Numerics.Vectors, System.Numerics, System' could not be found (yet they are in my .csproj file)

To fix this problem, try to remove these references. Then right click References -> Add Reference to re-install these components.

Best Regards,

Jarvan Zhang

One more question JarvanZhang-MSFT - why does Mono.Android only have 0.0.0.0 for their Version numbers?

JarvanZhang-MSFT - I have installed all of the System References with no change in error messages. The Android and System Namespaces are not being recognized. This is very frustrating. I've been held up by this for weeks. Not your fault of course, but should I just restart the project from the beginning? Is there something else I'm missing?

Hi, when is your project created? If it's created on the VS with very earlier version, there may be some conflits between the references\libraries. Try to create a new blank project and copy the sample code to it for test.

Hi JarvanZhang-MSFT. I've saved multiple instances of my project in Github and now have branches before the addition of the new Google Places API and after the installation of the new Google Places API. I do believe that the installation of the new Google Places API is corrupting something. I have a working app with no errors before the install and 325 errors after the install. This is very frustrating. I have tried all combinations of removing and reinstalling Nuget packages, changing the install order, going through and installing the dependencies individually, etc. Also, I started with a fresh new project today and literally rebuilt everything from scratch. Everything worked fine until the new Google Places API was added. Is there a way to continue to use the deprecated version?

I can send you an invite to look at the before and after branches, if you think you may find something. I am somewhat stumped.

It's suggested to report the issut to the author of the nuget on github to check if there's any workaround to get rid of this.
