期望类型和名称，而不仅仅是'setExtensionCallback'

Question

我正试图为我的应用程序生成签名的apk，但它失败了，返回错误Expecting type and name instead of just 'setExtensionCallback' before '(' in line 326 of file 'pathtofilereleaseconsumer-rules.pro',我不确定是什么原因造成的，也没有任何进一步的信息或任何详细的报告。这是consumer-rules.pro-的第325和326行

-if class androidx.window.layout.SidecarCompat {
public setExtensionCallback(androidx.window.layout.ExtensionInterfaceCompat$ExtensionCallbackInterface);
}

我正在为此使用dexguard。几天前它还在工作，但突然停止了。

这是dexguard-project.txt文件。

Answer 1

此问题现已在最新版本的dex-guard.9.3.3中修复

Answer 2

当我升级到依赖项的版本以下并且启用了pro-guard时，我的项目中也有类似的问题。我尝试了很多方法来解决这个问题，但最终，当启用pro-guard时，这个库的新版本似乎有任何问题。

因此，我必须降低依赖'androidx.preference:preference-ktx:$version'的版本

1.1.1版本对我来说很有效，解决了这个问题。

希望它也能解决你的问题！！

您是否可以尝试使用元数据保留所有类

-keep class androidx.window.layout.SidecarCompat {
*;
}
-keepkotlinmetadata
