.NET for Android error XA0031

Проблема

The Android SDK platform you are targeting only works with certain versions of Java. If you get this error, it means either:

1. You don't have a Java SDK installed, or
2. Your Java SDK version is too old or is otherwise not compatible with the targeted Android platform.

Решение

Make sure you install a compatible JDK version, such as the Microsoft Build of OpenJDK.

Примечание.

Java SDK 11.0 is required to use $(TargetFrameworkVersion) v12.0 (API-31) and later, and to use $(TargetFramework)=net6.0-android31.0 in .NET 6 and later.

Use of Java SDK 11.0 will break the Android Designer in Visual Studio 16.11 and earlier.
