Proguard 设置错误

Question

我在发布版本中启用 proguard 时遇到了这个问题。

信息：Gradle 任务 [:app:assembleRelease] 警告：com.google.maps.android.kml.KmlRenderer$1：在程序类 com.google.maps.android.R$id 中找不到引用的字段“int window”

警告：对程序类成员有 1 个未解决的引用。

Warning:Exception while processing task java.io.IOException: 请先更正上述警告。 错误：任务“：app：transformClassesAndResourcesWithProguardForRelease”执行失败。 作业失败，请参阅日志了解详细信息 信息：构建失败 信息：总时间：26.457 秒 信息：1个错误 信息：3 个警告 信息：在控制台中查看完整的输出

我的 Proguard 设置规则如下所示。

-keep class butterknife.** { *; }
-dontwarn butterknife.internal.**
-keep class **$$ViewBinder { *; }

-keepclasseswithmembernames class * {
 @butterknife.* <fields>;
 }

-keepclasseswithmembernames class * {
 @butterknife.* <methods>;
 }
-dontwarn io.card.**

Answer 1

看起来 KmlRenderer 类中的内部类试图访问生成的类 com.google.maps.android.R$id 中不存在的字段。使用更新版本的谷歌地图库可能会解决该错误。

您也可以使用

禁用警告

-dontwarn com.google.maps.android.kml.KmlRenderer
