xamarin.android - Xamarin.Android 无法使用 proguard 编译

问题描述

我有一个项目可以在 api 29 以下的任何版本中完美运行。

当我尝试在 Android 10 设备中运行时，应用程序在显示启动画面后崩溃。我发现的解决方案之一是将 proguard 与自定义配置一起使用：

-keep class android.support.v7.widget.FitWindowsLinearLayout { *; }
-keep class android.support.v7.widget.** { *; }

现在我尝试使用 proguard 进行编译，但出现错误。

/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.DX.targets(5,5): Error MSB6006: "java" foi encerrado com o código 1. (MSB6006) (Garcom)

  Tarefa em execução pronta "Proguard" -- FALHA.

proguard.cfg 构建操作设置为 ProguardConfiguration。我已经尝试过：

这些都不起作用。
