Yonglun Liu (Shanghai Wicresoft Co,.Ltd.) 50,126 Reputation points Microsoft External Staff2022-12-12T05:18:49.597+00:00 This should be caused by incompatibility between
Xamarin.Forms 5.0.0.2012andGoogle.Android.Material version : 1.7.0.1.In my tests, if I was using this version of
Xamarin.Forms 5.0.0.2012and then installingGoogle.Android.Materialversion 1.7.0.1, VS would get a prompt thatXamarin.AndroidX.Core (> = 1.9.0.1)was required.If you update
Xamarin.Formsto the latest version, will this issue still occur? -

2022-12-12T09:22:53.86+00:00 The update of Xamarin.Forms to 5.0.0.2545 and Xamarin.Google.Android.Material 1.4.0.6 leads to this error :
MSBUILD : java error JAVA0000: Error in obj/Debug/lp/211/jl/classes.jar:com/google/android/gms/ads/internal/overlay/zzaa.class:
MSBUILD : java error JAVA0000: Type com.google.android.gms.ads.internal.overlay.zzaa is defined multiple times:Maybe this one occurs the error : com.google.android.gms.ads.internal.overlay.zzaa is defined multiple times ?
If I return the version of Xamarin.Forms to 5.0.0.2012 this error is gone but is showed up the previous error with the ShellItemRenderer -

<PackageReference>elements from yourapp .csprojfile back in a new comment on this item?It would be helpful for us to find the cause of the conflict.
Thanks in advance!
