Question

我最近看到了proguard的使用，我在我的应用程序中使用谷歌分析服务。

在eclipse中我有 - proguard-project.txt 其中我添加了以下几行：

-keep class android.support.v4.** { *; }   
-dontwarn android.support.v4.**
-keep public class com.google.** {*;}

在项目属性中，我有未注释的行： -

proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

我想在我的项目中实现proguard但是使用以下控制台输出触发了错误代码1：

提前致谢。

Answer 1

您应该针对包含缺少的类android.util.LruCache的目标SDK构建;在这种情况下android-12或更高版本。只需将project.properties文件或build.gradle文件中的构建目标更改为该最新版本。

您仍然可以在minSdkVersion文件中指定其他targetSdkVersion和不同的AndroidManifest.xml。

Answer 2

也许请按照this SO question

中的说明尝试此配置

-keep class com.google.android.gms.analytics.**
-keep class com.google.analytics.tracking.**
-dontwarn com.google.android.gms.analytics.**
-dontwarn com.google.analytics.tracking.**
