Crash deploying net6.0-android app with android-arm and android-x64 RIDs #7654

Open gkarabin opened 1 year ago

gkarabin commented 1 year ago

Android application type

Android for .NET (net6.0-android, etc.)

Affected platform version

VS 2022 17.4.3

Description

The .net 6 template app will crash if you modify it to limit RID support to android-arm and android-x64 when deploying to an android-arm64 device. I have an app that has 32-bit ARM .so files that I reference, but does not have 64-bit versions of the same files for ARM. I do have 32-bit and 64-bit versions for Intel.

For legacy Xamarin Android I could specify <AndroidSupportedAbis>armeabi-v7a;x86_64</AndroidSupportedAbis>. For net6.0, specifying <RuntimeIdentifiers>android-arm;android-x64</RuntimeIdentifiers> results in an app that crashes with:

Steps to Reproduce

From a command prompt with VS 2022 17.4.3:

  1. dotnet new android
  2. Modify .csproj to target net6.0-android (rather than net7.0-android).
  3. Modify .csproj to contain <RuntimeIdentifiers>android-arm;android-x64</RuntimeIdentifiers>
  4. dotnet build -t:Run -f net6.0-android

I expect the app to launch and display "Hello Android!". Instead, the app launches to a white screen with no text.

Did you find any workaround?

Uninstalling the app from the Android device, then modifying the app to target .net7.0-android works as expected when building and running for net7.0-android.

It is a costly workaround - my app requires quite a bit of work to update to .net7.0 due to Android SDK requirement changes for MAUI.
