Basemap loading stopped working after switch over to TLS.

ITS_JohnColaneri — Tue, 14 May 2019 23:42:41 GMT

I seem to have gotten my Visual Studio 17, Xamarin Android project torqued into some untenable position. When I try to load a Basemap, it throws the following error:

I've used Android device monitor to look for these libraries, and indeed, they are not there on the device. The thing is, everything was *working* before April 16. Anyone have any ideas about how to chase this down? Also, probably relevant that I have another incarnation of the same project that does load the Basemap on the same phone (it has something else broken in it that makes it unusable..)

Hi,

Have you followed the guidelines in https://docs.microsoft.com/en-us/xamarin/android/app-fundamentals/http-stack?tabs=windows ?

It's also possible you just need to uninstall the app from your development/test device before re-deploying.

Cheers

Mike

Hi Mike,

I have already done both of those things, a month ago.

John,

Can you share more information about your Android project settings, minimum/target OS, test device, etc?

This shouldn't be necessary - but have you already tried the load library call in https://community.esri.com/message/762607-re-systemdllnotfoundexception-libruntimecorenet ?

Cheers

John,

There is some additional advice in this thread that might help: https://community.esri.com/message/766794-re-arcgis-runtime-10021-crashes-on-android-80-api-26

Hi Mike,

Minimum Android version is level 21, Target Android version is level 27. I’m usually running on a Samsung Galaxy S8. I’ve also run the same issues on a Samsung Galaxy Tab 4. The NuGets are Esri.ArcGISRuntime.Tookit v100.4.0, and Esri.ArcGISRuntime.Xamarin.Android v100.5.0.

I have not tried loading libraries manually. Might take me a non-trivial expenditure of effort to figure out how to do that in C#. Is that sort of thing not usually done through the Solution Explorer under References?

In any event, I’ve surfed around the file system on the device with Android Device Monitor, and looked in the locations mentioned in the Java error dump from the original post. Indeed the libraries in question are not there..

John,

Have you tried the steps in https://community.esri.com/thread/213518-arcgis-runtime-10021-crashes-on-android-80-api-26 ?

Regarding the load library call, it shouldn't be necessary to make that call manually (programmatically) - but if it works then it may point to an issue in our initialization.

Cheers

Mike

Hmm.. The steps delineated in that post produced the following error output:

This bit:

… in assembly: 'Esri.ArcGISRuntime.dll' ---> Mono.Cecil.ResolutionException: Failed to resolve System.String[] System.String::Split(System.Char,System.StringSplitOptions)…

Looks familiar. The part after “Failed to resolve” is the incomprehensible error output -e.Message- from the Exception thrown during execution..

Hmm.. I don’t think so. I’m set up with Linking: Sdk Assemblies Only. If I’m reading the article correctly, the (GC like) Linker should skip over the Esri libraries. Did I misinterpret what I read? Thanks.

Issue likely due to problems on my local network segment. Thank you.
