VS2019 16.2 Preview3 - 9.4.0.34 - My app crashes on Startup on Android 4.4

[michaldobrodenka]

Steps to Reproduce

1. Xamarin Android app with support libraries
2. Deploy to Phone/Emulator with Android 4.4 on Release & AOT
3. Crash

Since it seems related to resources, I've tried aapt1/2, Multidex On/Off (before this release Multidex was a must). My app has inherited Application class. On newer android emulators/phones app starts and runs without problems.

Expected Behavior

App start

Actual Behavior

Crash

[Abesoddy]

Same issue...

[jonathanpeppers]

@michaldobrodenka or @Abesoddy can you provide the full adb logcat output?

If it happened on your splash screen, can you make a small sample app I can try to see this?

[jonathanpeppers]

Ok, I was able to reproduce it with a new Xamarin.Forms Master/Detail template and a Android 4.4 / API 19 emulator.

It appears to be something related to aapt2, unchecking this box solved the issue for me:

It could also be related to this React Native issue where they are seeing the exact same error message/same API level: oblador/react-native-vector-icons#457

[cassionandi]

I had this problema even with debug mode. Yesterday I solved by uninstalling all "support" packages anda reinstalling.

[jonathanpeppers]

If you are specifically getting:

android.content.res.Resources$NotFoundException: File res/drawable/abc_vector_test.xml from drawable resource ID #0x7f080058

Then the command-line invocation of aapt/aapt2 needs the --no-version-vectors switch.

To workaround you can either:

• Disable aapt2 (aapt1 seems to work fine)
• Set <AndroidAapt2LinkExtraArgs>--no-version-vectors</AndroidAapt2LinkExtraArgs> in your csproj

I don't how reinstalling NuGet packages would fix it, unless you removed the Xamarin.Android.Support.Vector.Drawable NuGet package.

[cassionandi]

the project don't have Xamarin.Android.Support.Vector.Drawable NuGet package.
