Issue with FastRenderer

I got an exception while trying to use Glidex.Forms alongside FastRenderers_Experimental flag in Xamarin.Forms

here is a scenario which bug happens both PageA and PageB contains some images and we have enabled FastRenderer in android.

1. Applications starts in PageA
2. Navigate to PageB
3. Navigate back to PageA
4. Navigate to PageB again. the exception will be thrown here

@raulandresduque, we have no identified the difference or a root cause on how those builds are different. The build scripts looks like this msbuild $AndroidXamarinProjPath -t:UpdateAndroidResources -t:SignAndroidPackage -p:OutputPath=$OutputFolder/ -p:Configuration=Release -p:AndroidKeyStore=true -p:AndroidSigningKeyAlias=Alias -p:AndroidSigningKeyPass=pass -p:AndroidSigningKeyStore=$KeystoreFileNamePath -p:AndroidSigningStorePass=pass

I hope it will help you as well

SignAndroidPackage is the target that creates an .apk file and signs it.

I don’t think there is a reason to ever use UpdateAndroidResources.
